• Backend ownership: Own server‐side development for multi‐tenant data platforms serving 4 partner organizations in Bangladesh, India, and Timor‐Leste — Django/DRF APIs, PostgreSQL schema design, and Redis caching for large payloads consumed by both web and mobile clients, — including the official Abohawa app of the Bangladesh Meteorological Department.

• Built and maintained Node.js/Express backends and Angular admin dashboards for e‐commerce and event‐management platforms, covering inventory, order, and content workflows. • Refactored API layers across multiple projects, reducing server response latency by 35% and measurably improving maintainability for the team that inherited them.

• Developed Angular‐based ERP system as part of a product team, streamlining finance, inventory, and HR workflows — driving up to 40% improvement in data accuracy.

• Worked fully remote with a US team across a 10‐hour offset, building Django REST APIs for digital service autho‐ rizations, automated result delivery, and corporate invoicing on an occupational‐health SaaS platform.

• Contributed to a Shariah‐compliant core banking platform through testing, debugging, and issue tracking, and modernized legacy internal UI modules in Angular — first exposure to systems where a wrong number is a real financial consequence.
