Senior software engineer building scalable secure full-stack web apps.
BangladeshWhat I'm looking for
I’m a Senior Software Engineer with 7+ years designing and building scalable full-stack web applications with JavaScript and TypeScript. I focus on modern frontend and backend systems—turning robust architecture, testing, and automation into better reliability, faster deployments, and higher engineering productivity.
In my recent work at Cefalo Bangladesh Ltd., I contributed to full-stack development, infrastructure, database design, and architecture for the Cefalo Payroll Application. I engineered onboarding and personalization features that increased user retention by 23% and grew subscribed users by 5%, while also improving quality through 89% unit test coverage with Jest and reducing migration effort via automation scripts. I’m also a strong advocate of secure coding practices, with hands-on expertise aligned to OWASP standards, and I’ve built cloud-backed solutions using AWS services like Lambda, API Gateway, CloudFront, and CI/CD pipelines.
