About

A bit about me

Frontend-focused engineer with 3+ years of experience shipping products people rely on daily — fintech apps, ERPs, CRMs and internal tools. The focus: interfaces that feel fast, look polished, and remain easy for the next developer to change.

Most of the work sits where the frontend meets real constraints: field teams using an app all day, several clients on one codebase, or a migration that can't break a live product. Comfortable owning the architecture — and going down to native code or the backend when a feature needs it.

Up to date with AI-assisted engineering: coding agents such as Claude Code, reusable agent skills and project instructions (AGENTS.md, CLAUDE.md), and LLM APIs — used to move faster while keeping review and quality in human hands.
