What I'm looking for

I am looking for a dynamic work environment that fosters innovation and offers opportunities for professional growth, particularly in backend development and cloud technologies.

I am a dedicated software engineer with a strong foundation in computer science, holding a Bachelor's degree from the Islamic University of Technology. My professional journey began at Robi Axiata Limited, where I developed innovative solutions for mobile applications, significantly enhancing user experience and operational efficiency. I successfully implemented a QR-based recharge module that handled 70 million requests per day and optimized API response times by 20% through meticulous query and service enhancements.

Currently, I am contributing to bKash Limited, focusing on developing a recurring payment platform. My work involves migrating Java middleware to Go, which has streamlined our service architecture and halved hosting costs. I thrive on challenges and continuously seek to improve system performance and user satisfaction through effective backend solutions and cutting-edge technologies.
