What I'm looking for

I'm based in Dhaka and available for full-time onsite work.

At Celloscope, I developed Angular and TypeScript features for enterprise banking applications, then built secure APIs with JWT authentication and role-based access control for portals including ABS Portal, Ampere Portal and SMS Alert.

I also built a Maker-Checker approval workflow for merchant account operations and developed REST APIs with Spring Boot connected to Angular frontends. In my projects, I’ve worked on systems ranging from import management and agricultural accounting to retail POS and health platforms.
