Senior Full-Stack Engineer

I build web products with React, TypeScript and Node, mostly in fintech and payments.

My daily setup includes Cursor, Claude Code, Codex and Grok Bot.

How I work

I use Cursor, Claude Code and Codex for coding, reviews and tests, and Grok Bot agents to automate my day-to-day tasks. I review everything before it's merged.

  • Frontend first, comfortable across the backend.
