What I'm looking for

I'm seeking a Software Engineer role focused on backend engineering, system design, or full-stack and mobile application development, where I can build scalable services and production-ready applications.

At GearON, I owned end-to-end delivery of a two-sided automotive service platform for car owners, mechanics, and administrators. I designed secure role-based REST APIs for service bookings, job management, inventory, and purchasing and sales workflows.

I reduced API response time by 35% through query optimization and database indexing, and deployed and maintained the platform on a Linux VPS. It scaled to 300+ concurrent users and supported growth to 2,000+ active users in the Dhaka market.

At RubizCode, I built and maintained EdTech products including TopperOn, Testiphy, and BP Dream School. I implemented real-time features with Socket.io and worked on API integration and database management.

At Wevloper IT, I developed and maintained web applications and EdTech platforms, including backend services, RESTful APIs, and database management. My projects also include GoBNS, an online car marketplace, and a Twitter sentiment analysis project using NLP.
