Full-stack developer at JMT Network Services building internal systems people use every day — web admin panels, Node.js APIs and a Flutter field app. 1,818 commits across 8 production systems since October 2024. I use Claude Code as a structured part of the team workflow, and verify every release with Playwright E2E tests and SQL migrations with rollback.
