About Me
I'm a Full-Stack Developer & DevOps Engineer based in Dhaka, Bangladesh, building and shipping web and mobile products since 2014 — as a Senior Software Engineer full-time, and as an independent freelancer for long-term client partners. Over the years I've shipped everything from real-time chat apps to fleet-management systems, always focused on clean architecture and dependable delivery.
My work spans the full stack: JavaScript/TypeScript (Node.js, React, Next.js, Angular, Vue, Express), PHP (Laravel, CodeIgniter) and Python (Django, Flask) on the backend; MySQL, PostgreSQL, MongoDB and Oracle for data; and cross-platform mobile with React Native, Flutter, Ionic, Swift and Java. On the infrastructure side, I containerize and deploy with Docker and Kubernetes, build CI/CD pipelines, and manage cloud infrastructure on AWS/GCP — so apps don't just work locally, they ship, scale and stay up. Beyond typical web development, I regularly take on specialized work — secure messaging systems, web scraping and data-extraction pipelines, AI/LLM-powered features, and security audits of servers and codebases — the kind of problems clients bring me when they need someone who can go deeper than a surface-level build.
Whether I'm brought in for a single feature or a long-term retainer, I care about clear communication, realistic timelines and code that's still easy to maintain a year later — an approach that's earned top ratings across nearly every completed project on Upwork and a track record of long-term client relationships.
