About

High-agency software engineer with experience shipping production SaaS products, AI/RAG workflows, billing systems, and third-party integrations in fast-moving startup environments.

Strong ownership across frontend, backend, API integrations, and LLM-powered data retrieval. I learn any stack fast and ship under pressure.

How I Work

Most of my building now runs through agentic coding tools like Claude Code, Cursor, Codex, and opencode. I usually have a few agents working at once on different parts of a problem, so my real job is less typing and more deciding: scoping the work, reviewing every diff, and keeping the architecture coherent.

I keep agents on-rails with project conventions like AGENTS.md and SKILL.md, watch for prompt-injection and bad assumptions, and verify before anything ships. The tooling changed how fast I move, not who's accountable for the result.
