About

Full-stack developer in Waterloo, Ontario. Seven years in POS, payment and accounting integrations, now building in TypeScript, React, Node and Python. I shipped TetherPOS, an offline-first React point-of-sale used by a paying retail client, and a Python IMAP service that exposes LLM-assisted extraction over MCP for a second client. I write SQL for reporting, document what I build, and hand over code with usage instructions. I study Computer Programming at Conestoga College, so I take fixed-scope projects with agreed milestones.
