Your AI SaaS works in the demo, then breaks the moment real users hit it. I build the version that doesn't, the kind running in production right now, moving 10,000+ clinical messages a day at 99% delivery and saving one client $400K a year. RAG that doesn't hallucinate, agents that survive edge cases, multi-tenant data that stays sealed. And where it matters most, in regulated healthcare and fintech, that's the work I'm known for. WHAT MAKES ME DIFFERENT Most developers build exactly what you spec. You get someone who tells you what the business actually needs first, before you spend the budget, then builds it to last. Five plus years leading architecture, making build-versus-buy calls, and operating as fractional CTO for founders without a full-time technical hire. The rare part: shipped HIPAA-compliant healthcare systems and SEC-compliant fintech infrastructure to US standards, where audit trails and reliability are non-negotiable. Few AI developers can claim that honestly. PROVEN IN PRODUCTION The VP of Enterprise Solutions at Fukuda Denshi USA endorsed an HL7 gateway I built for their HealthMosaic platform, now moving 10,000+ clinical messages a day from 200+ hospital monitors at a 99% delivery rate, saving an estimated $400K a year. For a US fintech startup, a SEC Reg CF compliant backend with 248 passing tests and zero production bugs. What clients say: "He thinks like a product owner, not just a developer, and delivered production-ready work ahead of schedule." Justin R., VP of Enterprise Solutions, Fukuda Denshi USA "By far the best developer I've worked with. If you need someone who delivers, hire him." Carmen M., Business Consultant "Clean, well thought out design, finished weeks ahead of schedule." Jett S., Founder, NxtSzn If you're building in AI, healthcare, fintech, or any SaaS where it has to work the first time, send me what you're building. You'll hear back within a day on whether I'm the right fit, and I'll tell you straight if I'm not.
