I build production software, web applications, and mobile products end to end: from requirements and architecture through implementation, deployment (DevOps), and ongoing improvement.
Six years shipping real-time, AI-powered, and queue-driven systems for teams and clients.
I'm a full-stack product engineer based in Dhaka with six years of experience building production web, mobile, and automation systems. I work across the full product lifecycle, from requirements and architecture to implementation, deployment, and ongoing improvement.
I take ownership of complete workflows rather than isolated tickets. My work spans user-facing applications, backend services, real-time communication, background processing, data systems, and production infrastructure.
I focus on systems that remain reliable under real workloads. That means designing for failure recovery, observable background jobs, maintainable architecture, and practical delivery instead of unnecessary complexity.
Clear tradeoffs, reliable delivery, and software teams can maintain after launch.
The core capabilities I use to take products from interface and application logic to distributed processing and production infrastructure.
Production web interfaces and cross-platform mobile applications built around real product workflows.
APIs, business logic, integrations, and background services designed for maintainability and failure recovery.
Queue-driven processing, real-time communication, and data stores supporting high-volume production workloads.
Repeatable deployments, cloud infrastructure, and Linux operations from provisioning through monitoring.
What I built, the decisions behind it, and how each system works in production
