I'm a senior full-stack engineer and systems architect with 24 years building infrastructure and platforms at Microsoft, Amazon, Oracle, and ServiceNow. I bring that depth to focused, well-scoped client work and deliver it at startup speed: well-defined projects in days, not weeks. Most recently I designed and built a complete HIPAA-compliant healthcare platform from zero to production, solo. That included multi-tenant architecture, role-based access control, insurance claims processing (EDI 837P and 835 ERA plus real-time eligibility), telehealth video, automated clinical workflows, and a full client portal. The range there, from data modeling to third-party API integration to security hardening, is the range I bring to your project. Where I do my best work: Well-specified builds: API and systems integrations, dashboards, internal tools, and complete small to mid-sized applications Connecting systems that were never meant to talk to each other (payment processors, clearinghouses, CRMs, and third-party APIs) Python and Django backends, AWS infrastructure, and the full stack around them Taking a clear spec and returning working, tested software quickly How I work: I prefer fixed-price engagements, so you know the cost up front and pay for the delivered result rather than logged hours. I ask the questions that matter before I start, communicate clearly throughout, and hand off tested code. I take on projects where the requirements are well-defined, because that is where I move fastest and where you get the most value for your budget. If you have a defined build and want it delivered correctly and quickly by an engineer who has operated at a principal level, send it over and let's talk through it.
