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.

Most developers build features. I build systems that handle real users, real payments, and real scale. I specialize in backend-heavy SaaS platforms where things break if not designed properly — payments, real-time flows, multi-tenant logic, and high-traffic systems. ⚡ What I bring → 7+ years of production experience → Strong system design mindset (not just feature delivery) → Backend architecture using NestJS (Node.js) + FastAPI (Python) based on best-fit → Real-time systems (WebSockets, concurrency handling) → Payment systems (Stripe, webhooks, subscriptions) → Multi-tenant SaaS platforms 🔥 Proven Work → Multi-tenant system → AI-powered ticketing system (secure backend AI + automation workflows) → AI document generation system (FastAPI-based backend) → Noloco + Airtable + Stripe-based lead marketplace → High-traffic eCommerce platforms (4k+ daily users) → Streaming platform (real-time video using Agora) → Blockchain systems (ICO, NFT marketplace, crypto wallet) 🧠 How I think Before coding, I identify: → Where your system can break (webhooks, race conditions, scaling issues) → What needs strict consistency vs flexibility → Whether NestJS or FastAPI is the better choice 🛠 Tech Stack → Node.js, NestJS, TypeScript → Python, FastAPI → Next.js, React → PostgreSQL, MongoDB → Stripe, WebSockets → AWS, Vercel, Railway → Airtable, Noloco, Zapier, Perspective ⚡ Working Style → Fast, clear communication → Clean, maintainable code → Works within your system (no unnecessary rewrites) → Focus on long-term scalability If you're building a serious SaaS, AI system, or payment-driven platform — I can help you build it right from the start.

I build and ship AI-powered SaaS, and I have a live one to prove it. Founders hire me to take an idea to a working, paid product. My own SaaS, Outshipper, runs in production today: a multi-stage AI pipeline that pulls live data from the web, runs it through a chain of language-model steps, and returns answers backed by real citations instead of made-up ones. It handles its own payments and runs lean on cost. I built the whole thing. What I do for clients: Full-stack SaaS on Next.js, React, Supabase, and TypeScript AI features that ground their answers in your real data (RAG), not guesswork Payments and subscriptions (Stripe), login/auth, and multi-tenant data security Workflow automation with n8n to take the manual busywork out of your operation Where I'm different: before AI, I spent close to a decade in SEO and marketing. So I don't just build the product, I think about whether people will find it and buy it. If your tool needs to rank, convert, or pull competitive intel, that's an edge most developers can't offer. How I work: I'm honest about trade-offs, I ship in small working pieces you can see along the way, and I don't go quiet. You'll always know where things stand. If you're a founder with an idea, or you have a half-built product that stalled, send me the details and I'll tell you straight how I'd take it the rest of the way.
