I’m a Backend Developer with hands-on experience building and maintaining scalable REST APIs using Node.js, Express.js, NestJS, TypeScript, and PostgreSQL. I focus on production-grade reliability for logistics and fintech platforms, with strong fundamentals in authentication and authorization and database design.

At Naql Logistics, I developed REST APIs and worked in a monorepo architecture supporting backend, web, and mobile applications. I designed and optimized PostgreSQL queries, implemented authentication, authorization, validation, and error handling, and added pagination, filtering, and sorting for role-scoped endpoints—plus bid module APIs with paginated response shaping and route-level fixes.

At ThankioPay, I single-handedly designed and developed the admin dashboard frontend, building reusable UI components with a component-based architecture. I used MUI and Tailwind CSS with responsive layouts, integrated the frontend with backend APIs, and extended into backend work with NestJS and TypeScript—helping design and implement a wallet ledger system to ensure accurate transaction tracking and balance management.

I’ve also contributed to other builds, including backend bug fixes in an Order Management System using NestJS, MedusaJS APIs for a cake customization platform, and bug fixes in a Murshedd Chrome Extension project. My academic foundation includes a thesis on a Paper Submission System (PHP + MySQL).
