Partners Online (Bangladesh & UK) — Operation Manager, Web & App Development
March 2026 – Present · Dhaka, Bangladesh (Remote · part-time) · No Borders IT / Partners Online BD & UK Ltd
- Own the platform behind Partners.com.bd — Bangladesh's marketplace + business-social platform expanding into the UK — end to end: backend architecture, database, cloud infrastructure, deployment, scalability, and security across BD and UK operations.
- Cut detail-page round trips from 3–4 to 1 (~70% fewer) by leading the legacy MVC → API strangler migration to a Clean Architecture .NET API — retiring the monolith with zero downtime while three Flutter apps (General, Executive, City) ship on top of it.
- Closed the double-settlement money-loss path by construction: one generic payment ledger serving every paid feature, a vendor-agnostic gateway abstraction with country-aware resolution, and a self-healing settlement coordinator backstopped by Hangfire reconciliation.
- Made background work crash-safe — no job silently lost or double-run — with a transactional SQL outbox, a dedicated Hangfire worker under a least-privilege SQL principal, a dead-letter queue, and idempotency keys.
- Bounded CDN storage cost structurally: an async image pipeline whose server-owned
lifecycle guarantees every orphaned upload is swept without client cooperation; also
open-sourced the team's document-driven agent workflow as the
d3Claude Code skill.
