Senior Full-Stack AI SaaS Architect · Next.js · Node.js · TypeScript · AI Agents
I architect and ship production AI-native SaaS platforms — orchestrating AI as an engineering team instead of typing every line myself.

15+ years building for the web — now a senior architect running a mature, production-grade AI-native workflow. I treat AI as a team of ~7 specialized Claude Code sub-agents and act as architect/supervisor: scoping, reviewing, integrating. Result: features that used to take 16 hours ship in ~1 hour, at production quality, with ~70% less operational overhead.

I help SaaS founders and product teams go from idea to a shipped, fast, maintainable platform — and turn slow manual ops into automated pipelines.

I build full-stack web apps across the niches where I have deep, shipped experience:

• AI SaaS & AI-agent platforms — Next.js AI SaaS, multi-tenant Node.js SaaS, AI-agent & LLM features, RAG, AI model integration
• FinTech web apps — React + Node.js fintech platforms, trading algorithms, technical-analysis & TradingView UIs, real-time WebSocket data
• E-commerce engineering — Next.js & React storefronts, Shopify / headless commerce, Stripe & payment-gateway integration
• Adobe Commerce / Magento 2 frontend (Adobe Certified Expert) — Hyvä Themes (Alpine.js + Tailwind), PHP, Knockout.js / Luma, RequireJS, XML layout, GraphQL headless, performance & technical SEO
• Analytics dashboards — Next.js & React dashboards, data visualization, Node.js analytics platforms
• B2B APIs & backend — NestJS / Node.js REST & GraphQL APIs, PostgreSQL & Supabase, microservices, FastAPI
