🚀 I build production-ready AI products, SaaS platforms, payment systems, and full-stack web apps. If your product is half-built, technically messy, or needs someone who can own more than just tickets, I can help turn it into something real, reliable, and shipped. I’ve built AI agent platforms, embeddable widgets, SDKs, dashboards, data integrations, and payment flows used in real businesses. ━━━━━━━━━━━━━━━━━━━━ ⚡ Proof in one line Built AI agent infrastructure, shipped 385+ PRs across 10+ repos, helped improve onboarding conversion from 3% to 8%, owned payment systems growing from ~$420K/day to ~$625K/day, and worked on a platform that later crossed ~$4M/day in transaction volume. ━━━━━━━━━━━━━━━━━━━━ 🧠 What I build • AI agents, generative UI, LLM apps, and data-connected assistants • Full-stack SaaS products with React, TypeScript, Node.js, NestJS, and PostgreSQL • Dashboards, internal tools, customer portals, admin panels, and workflow systems • Payment integrations, gateway flows, SDKs, widgets, APIs, and automation • Production cleanup for products that need speed, reliability, and better architecture ━━━━━━━━━━━━━━━━━━━━ 🏗️ Recent work • Built major parts of Thesys Agent Builder, a no-code platform for creating and deploying AI agents with interactive UI • Architected 9 data integrations including PostgreSQL, MongoDB, MySQL, Snowflake, ClickHouse, Databricks, Neon, MotherDuck, and file uploads • Built an embeddable AI agent widget with tray, fullscreen, chatbar, theming, session handling, and white-label support • Shipped Claude-powered onboarding that helped lift conversion from 3% to 8% • Owned payment systems processing hundreds of thousands of dollars per day • Reduced a payment authentication frontend from ~10 MB to ~200 KB with no functionality loss • Improved a scraper by 1150% and made it horizontally scalable ━━━━━━━━━━━━━━━━━━━━ 🤝 How I work I ask the right questions early, map the simplest reliable path, and then ship. You get clear communication, practical tradeoffs, clean implementation, and someone who can think across product, frontend, backend, data, infrastructure, and UX. No endless handoffs. No vague engineering fog. Just thoughtful execution and a product that moves forward.
