Who you would actually be working with

I’ve been the end user, the IT specialist handling the implementation, and the developer writing the code. That unique combination gives me perspective from every side of a project.

What I build

End to end development, from the first sketch to a shipped, supported product.

Mobile apps

Native and cross-platform iOS and Android applications.

Web applications

Responsive web apps, portals, and internal tools.

.NET / IIS systems

Windows-hosted line-of-business apps, services, and APIs.

Integration & modernization

Connecting systems and bringing legacy software up to date.

We Go Deep

I have spent years inside Defense Health Agency (DHA) and Med-COI environments, so I understand the constraints and compliance rules most developers never see. I build to fit how these systems actually work, not how a demo pretends they do.

  • HIPAA compliance
  • CAC and PIV authentication
  • ATO and RMF processes
  • IIS and SQL Server on Windows Server
  • REST API design and integration
  • Reporting and data migration

How we can work together

For agencies & primes

Federal

  • Available as a subcontractor to established primes.
  • Comfortable with the ATO, RMF, and federal procurement process.
  • Available for staff augmentation or defined-scope deliverables.
  • Capability statement available on request.
For businesses & direct clients

Commercial

  • Fixed-scope projects or ongoing development.
  • Discovery, build, launch, and long-term support.
  • Clear scope and pricing agreed up front.
  • Direct access to the developer, no layers or handoffs.
