I spent 5 years as a scientist at Regeneron Pharmaceuticals. Now I build full-stack MVPs and SaaS products for founders who need software that works on day one, not day ninety. My stack is Next.js, React, Node.js, and Python, with AI integrations baked into most of what I ship. Here's what that looks like in practice: - SaaS platforms with auth, Stripe payments, and admin dashboards - AI-powered products: document extraction, email classification, voice agents using OpenAI and ElevenLabs - CRM and lead management systems with automation rules - Marketplace and e-commerce builds with vendor management - Healthcare, fintech, and construction ops tools - React Native mobile apps The R&D background isn't a footnote. When your code runs in a research environment, you don't get to ship something that "mostly works." That discipline stuck. I think about edge cases before they become production bugs, and I'm already considering what saves you money three months from now. I've shipped 24+ projects across 15 industries. My portfolio below has live deployed demos, not screenshots. Click around. My Upwork track record is still early. But every contract so far is 5-star with 100% Job Success. The work history outside this platform is where the depth is. Portfolio and GitHub show it. Message me with a quick description of what you're building. I'll respond within a few hours with whether it's a fit and a rough scope estimate. -- Humam
