What I build

Practical software for real operations

These are not cookie-cutter templates with the labels changed. Each application is built around the way a business actually works — the people, the data, the steps, and the decisions that happen every day.

Applications

Custom business applications

Line-of-business apps shaped to your process instead of forcing your team into someone else's software.

Platforms

Hosted SaaS-style platforms

Multi-user, multi-tenant web platforms with their own accounts, roles, and billing-ready structure.

Workflow

CRM & workflow systems

Contacts, deals, tasks, and pipelines wired to the actual stages your business moves work through.

Growth

Lead generation & enrichment platforms

Business discovery, contact intelligence, and data enrichment feeding a clean sales pipeline.

Visibility

Monitoring & remote probe platforms

Uptime, service, and device monitoring with local and remote probes and sensible alerting.

Security

Security & threat intelligence tools

Vulnerability awareness, email security, and threat-intelligence tooling built from MSP experience.

Internal

Internal dashboards & admin portals

Internal control panels that pull scattered data into one place your team can actually use.

Automation

Automation & scraping systems

Scheduled jobs, scraping, and enrichment that remove repetitive manual work and keep data fresh.

Integration

API integrations

Connect existing software, databases, email, billing, phone, and monitoring systems so they work as one.

Portals

Business-specific portals

Customer, client, vendor, and employee portals built for the exact way each group needs to interact.

Reporting

Reporting & analytics tools

Dashboards and reports on top of your own data — searchable, exportable, and built around the numbers you actually track.

Infrastructure

Infrastructure-backed web applications

Apps designed with hosting, uptime, backups, and recovery in mind from the first line of code.

Why custom applications matter

Most businesses don't need more software subscriptions

They need the right software — built around the way they already work, with room to improve. A custom app fits the business instead of asking the business to bend around generic tools.

  • Built around your workflow instead of forcing you to adapt to generic software.
  • Eliminates repetitive manual work and re-keying between disconnected tools.
  • Combines several scattered systems into one place your team actually uses.
  • Gives the business real ownership and the flexibility to change as you change.
  • Integrates with existing software, APIs, databases, email, CRMs, billing, phones, and reporting.
  • Supports role-based access, admin and customer portals, dashboards, automation, and alerts.
  • Avoids paying for bloated SaaS full of features you don't need and never asked for.
  • Makes your data easier to search, report on, export, protect, and back up.
  • Turns real-world processes into repeatable, dependable software workflows.
The whole application lifecycle

More than development — built, hosted, maintained, and improved

I don't just hand over code and disappear. I can build the app, host it, secure it, monitor it, back it up, update it, and keep improving it as the business grows.

01 Design & build

Workflow mapping, database design, application development, user roles and permissions, dashboards, and admin tooling — shaped around how the work really flows.

02 Host & secure

Hosting setup, server configuration, security hardening, and SSL/TLS handled cleanly in front by Nginx Proxy Manager while the app stays simple and locked down internally.

03 Protect & monitor

Backups for files and databases, monitoring for uptime and health, performance tuning, and deployment/rollback planning so changes are safe to ship.

04 Maintain & improve

Patching, updates, dependency review, bug fixes, feature improvements, and ongoing infrastructure support — the part most "we built it and left" projects skip.

Security, hosting, backups & maintenance

Security from real operations, not a checklist

My security experience comes from years of protecting real client systems in the MSP world — patching, monitoring, backups, firewalls, access control, and incident prevention — not from a certification binder.

  • Applications hosted in a professional datacenter environment.
  • Public HTTPS handled cleanly in front by Nginx Proxy Manager, while the backend stays simple and locked down internally.
  • Firewall rules, least-privilege access, hardened server configuration, and separation of public and private services.
  • Restricted, protected admin areas that are not publicly exposed unless intentionally designed to be.
  • Backups for application files, databases, and server-level recovery.
  • Updates and patching handled as part of ongoing maintenance.
  • Monitoring for uptime, performance, storage, services, application health, and SSL expiration at the proxy.
  • Secure authentication with two-factor authentication (2FA), role-based access, and a security-focused architecture from the first design decisions.
  • Brute-force and abuse protection with fail2ban, rate limiting, and GeoIP filtering built into the apps.
  • Maintenance includes patching, dependency review, server monitoring, backup validation, and operational support.
  • Built by someone who has answered the support calls when security and uptime actually mattered.

Datacenter compliance & assurance standards

PCI DSSSOC 1 Type IISOC 2 Type IISOC 3HIPAAISO 27001SSAE 18HITRUST

The datacenter environment used for hosted applications maintains major compliance and assurance standards including PCI DSS, SOC 1 Type II, SOC 2 Type II, SOC 3, HIPAA, ISO 27001, SSAE 18, and HITRUST. Application-level compliance depends on the app, its data, users, policies, and the controls each project requires — but the hosting foundation starts with a compliant datacenter environment.

Why choose me

Decades of experience — and someone who also runs the infrastructure

This is different from a front-end-only developer, a generic web designer, or a SaaS reseller. I build the software and operate the systems it runs on — backed by decades of development, MSP ownership, security, and business operations.

My experience goes back to programming in machine language in the 1980s. Since then, I have spent decades building, supporting, securing, hosting, and troubleshooting real business systems. From 1999 until 2023, I owned and operated an MSP, which means I was not just writing code — I was supporting clients, solving operational problems, maintaining infrastructure, securing environments, handling backups, managing vendors, and understanding how businesses actually run.

That background matters. A custom application is not just screens and buttons. It is workflow, data, security, uptime, backups, support, permissions, reporting, and long-term maintainability. The goal is software that fits the business and keeps working after it goes live.

“Custom software is better when the person building it understands the whole environment around it — the users, the workflow, the servers, the security risks, the backups, the support calls, and the business pressure behind the request.”

  • 1980s Machine-language beginnings Started programming close to the metal — decades of hands-on technical depth, not just recent web work.
  • 1999 – 2023 Owned & operated an MSP Client support and helpdesk, security, servers, networks, firewalls, virtualization, email systems, backups, monitoring, and business continuity — for years, for real clients.
  • 1999 – 2023 Built applications for real operations During my MSP years I developed several internal and client applications — including a debt collections application — to solve actual operational problems, not as demos.
  • Infrastructure Datacenter & hosted systems Datacenter builds, hosted environments, networking, storage, firewalling, backups, monitoring, and client environments.
  • Operations Owned and operated, end to end Sales, billing, employees, service delivery, customer expectations, escalations, emergencies, vendors, and the operational friction software is supposed to remove.
  • Today Custom hosted applications Development, infrastructure, security, support, and business operations — applied together to build apps that are practical, supportable, and useful in the real world.

What sets this apart

  • I build software and operate infrastructure. Hosting, networking, security, backups, monitoring, and support are part of the same job.
  • I can build the app and keep it running. Not a hand-off — a long-term, maintained system.
  • Designed around exact workflows. Features added over time as the business changes.
  • Integrated with your existing tools. APIs, databases, email, billing, and reporting.
  • Security & maintenance are part of the process. Access control, patching, hardening, and risk reduction considered early.
  • Practical software, not vanity websites. Tools that do operational work every day.
  • MSP ownership means I understand the pressure. Client expectations, support load, recurring issues, vendors, and billing.
What makes these apps different

Security-focused, owned by you, and never outsourced

The difference isn't a longer feature list — it's who builds the software, how it's built, and what happens after it ships. These apps are engineered the way I protected client systems for two decades.

Security first

Security built in, not bolted on

Access control, least-privilege, hardening, and a clear public/private separation are design decisions made on day one — not patches added after something goes wrong.

No outsourcing

Built by me, start to finish

Your application is not farmed out to an offshore team or a rotating cast of contractors. One accountable builder designs it, writes it, hosts it, and maintains it.

Accountability

One person who answers the phone

The person who wrote the code is the person who fixes it. No support tier to escalate through, no "that was a different team" — direct answers from someone who knows the system.

Ownership

You own your app and your data

No per-user taxes, no feature lockouts, no forced cloud, no losing access to your own data. Export it, back it up, integrate it, and keep using it.

Operations

Designed to be run, not just shipped

Backups, monitoring, updates, and recovery are part of the build — because an app that can't be operated reliably isn't finished, no matter how it demos.

Longevity

Built to be maintained for years

Clean, supportable architecture and ongoing maintenance, so the app keeps working — and keeps improving — long after it goes live.

Selected work

Open-source work and commercial applications

Some projects are commercial. Some are built because they should exist. The open-source work is a way to give something back, share useful tools, and show real development in public — the same practical approach used in the commercial projects.

Prototype

Build a practical first version quickly enough to test with real users and adjust early.

Build

Develop the application, database, permissions, dashboards, integrations, and admin tools.

Host & secure

Deploy internally behind NPM / Nginx Proxy Manager with hardened config, firewalling, backups, and monitoring.

Maintain & improve

Ownership, not lock-in

Your software should work for you — not trap you

No per-user taxes. No endpoint taxes. No artificial feature lockouts. No forced cloud hosting. No enterprise-only bait and switch. No losing access to your own data.

Why pay simply for permission?

Why pay just for permission to use software, or to access your own data? Custom and open work means you can self-host it, control it, back it up, modify it, integrate it, and keep using it.

Revenue from real value

The value is in real services — support, hosted deployments, priority assistance, integrations, security work, custom development, sponsored development, migration, and onboarding — not in locking you out of what you already paid for.

FAQ

Common questions

How projects run, how they're priced, where AI fits, and exactly how your application and its data are protected.

How does the process work?

It starts with a conversation, not a contract. I learn how your business actually operates — the workflow, the people, the pain points, and what "done" looks like — then map that into screens, roles, data, and reports. From there I build a practical first version, refine it with real users, then handle hosting, security, backups, and monitoring before it goes live. After launch I keep patching, improving, and adding features as the business changes.

The short version: discovery → workflow mapping → prototype → build → host & secure → maintain & improve. You're involved at every step, and nothing ships that you haven't seen working.

How do you quote projects?

Every quote follows a short discovery and workflow-mapping step, because an honest number depends on what the application actually has to do — the screens, the data, the integrations, the user roles, and the hosting and security requirements. Once the scope is clear, you get a written estimate tied to that scope.

Larger builds are usually broken into phases so you can see working software early and spread the work out, rather than paying for one large all-at-once delivery. Ongoing hosting, maintenance, and support are quoted separately so you always know what's a one-time build cost and what's recurring. No surprise line items, and no charging you for access to your own software later.

Do you use AI to build the applications?

Yes — but as a helper, not the author. AI is used to speed up and automate repetitive work: boilerplate, refactoring, test scaffolding, documentation, and research. The decisions that matter — the layout, the design, how the application actually works, and the security review — are done by a human who understands the whole environment around the app.

AI accelerates the busywork so more time goes into the parts that determine whether the software is actually good: the workflow fit, the data model, the edge cases, and the security posture.

How do you check the security of the code?

Every application is checked with my own security scanning product, ExploitHound — the same tooling sold commercially is used to vet the code I ship. It's a full-stack check, not just a quick lint of the application code:

  • Application code checked against known CVEs, zero-day patterns, and common exploit classes (injection, auth bypass, insecure deserialization, and similar).
  • Dependencies and libraries reviewed for known vulnerabilities and kept patched, so a flaw in a third-party package doesn't become a flaw in your app.
  • The underlying platform — operating system, runtime, web server, and database — scanned and hardened, because most real-world breaches happen below the application layer.
  • Threat intelligence and prioritization so the issues that are actually being exploited in the wild get fixed first, instead of drowning in low-risk noise.

Security isn't a box ticked at the end — it's checked from the first design decisions through every update.

How are the applications protected once they're live?

Security is built into how each application is hosted and run, not bolted on afterward. Depending on the app, the protections layered in include:

  • fail2ban — watches authentication and service logs and automatically bans IP addresses that show malicious patterns (repeated failed logins, probing, abuse), so attacks are stopped at the firewall instead of hammering the app.
  • Brute-force protection — rate limiting, throttling, and lockouts on login and sensitive endpoints, so password-guessing and credential-stuffing attempts are slowed to a crawl and blocked.
  • GeoIP filtering — traffic from regions that have no legitimate reason to reach your app can be restricted or blocked, shrinking the attack surface to where your real users actually are.
  • HTTPS everywhere — public TLS is terminated cleanly in front by Nginx Proxy Manager, while the backend stays simple and locked down on a private network.
  • Least-privilege & hardening — firewall rules, restricted admin areas, hardened server and service configuration, and a clear separation between public and private services.
  • Secure authentication — strong password handling, optional two-factor authentication, role-based access control, and session protections.
  • Monitoring & patching — uptime, health, and security monitoring with ongoing OS, dependency, and application updates as part of maintenance.

Which layers apply depends on the application and its risk profile, but the goal is always the same: make the easy attacks fail and the rest expensive.

How are backups handled?

Backups cover application files, databases, and server-level recovery. They're stored on a dedicated backup server I operate, then replicated to additional backup servers so a single failure — hardware, location, or otherwise — doesn't put your data at risk. Backups are validated as part of ongoing maintenance, because a backup you've never restored is just a hope, not a recovery plan.

Do I own the application and my data?

Yes. We can structure the agreement so you own the application outright and can take it — and your data — with you anytime you choose to leave. No per-user taxes, no feature lockouts, no forced cloud, and no losing access to what's yours.

Or you can keep it hosted with us, where security scanning, backups, and uptime are all automated and handled for you. Either way the choice is yours, and it's yours to change later — the value is in the real services around the software, not in trapping you behind recurring access fees.
