What I'm looking for

I’m looking to build and scale React/Next.js products with reusable components and strong performance. I want a team where I can own features end to end and ship reliable updates through Agile sprints.

I’m a Frontend Engineer with 1.5 years of hands-on experience delivering production-grade web applications. I focus on scalable UI systems, clean architecture, and reusable components that make teams faster and products more reliable.

At Mir Info Systems, I built an enterprise Service Request (ESR) dashboard to improve internal order processing workflows and delivered a Cockpit real-time order tracking application for better operational visibility. I also implemented Jest-based unit testing to reduce UI regression issues and increase reliability.

I’ve worked across authentication and API-heavy workflows, including integrating SSO authentication using Bkash and third-party secure login systems. I’m comfortable refactoring legacy frontend modules to reduce technical debt, improving maintainability, and resolving critical production bugs in telecom ecosystem applications.

On the product side, I’ve developed responsive dashboards and e-commerce experiences using React and Next.js, optimized rendering to reduce unnecessary re-renders, and collaborated in Agile/Scrum teams to ship end-to-end features. I also enjoy building user-focused systems like role-based access dashboards, real-time parcel tracking, and polished booking/search flows.
