Senior Full Stack Engineer with 12 years of experience building scalable web products end-to-end. I ship production software in spec-driven environments, collaborate closely with product and engineering teams, and focus on infrastructure optimization and reliable remote delivery. I build product features, backend services, and platform improvements across React/Next.js, Node.js, and Python, and I leverage AI-assisted development workflows (e.g., Claude Code/Cursor/Codex) to increase speed and quality. I’m also comfortable developing complex client-side experiences like in-browser video manipulation and AI-generated UI.…Senior Full Stack Engineer with 12 years of experience building scalable web products end-to-end.
