Software engineer in Dhaka, Bangladesh (UTC+6), open to remote. 3.5+ years building reactive, signals-first interfaces in Angular and React — and the .NET / Node behind them, down to the database and the monitoring that watches it.
Four enterprise ERP platforms, a multi-tenant SaaS, and 6+ products live, across three companies since 2023 — each running behind its own self-hosted observability stack. Modules shipped: access control, accounting, HR, production, inventory on the ERP side; deviation, checklist, handbook, compliance, settings on the QMS side. I work AI-native — Claude, Cursor, Ollama and OpenCode as a force multiplier, not a shortcut.
