Frontend-focused Fullstack Developer with 5+ years of commercial experience building complex, enterprise-scale web applications.
My main stack is React, Next.js and TypeScript, with solid backend experience in Python / Django and Node.js / Express. I apply AI deliberately across the delivery process — spec-driven development and agent-driven implementation as disciplined engineering practices, not novelty.
Frontend: React · Next.js · TypeScript · JavaScript · Vue.js · Tailwind CSS
Backend: Node.js · Express · Python · Django · Django REST Framework · PostgreSQL
AI & Automation: OpenAI API · LangGraph · LangChain · Claude · AI Agents · Prompt Engineering
Tools: Docker · Git · CI/CD · Claude Code · Cursor · Figma
I build production features on top of LLMs — OpenAI API, LangGraph and LangChain — and use spec-driven and agent-driven workflows to ship faster without sacrificing quality.
