Full-Stack Software Engineer

I own the end-to-end architecture and delivery of an Order Management System supporting more than 120 daily orders. The platform covers lead capture, order lifecycle management, role-based workflows, and a real-time duty-session and location-tracking module for over 35 employees, replacing manual coordination with a unified production system.

I architected a marketing attribution and tracking platform using RabbitMQ for event-driven collection, campaign attribution, and conversion measurement. I also integrated backend services for a proxy infrastructure reselling platform using NestJS, GraphQL, PostgreSQL, supplier APIs, sticky-session IP routing, and Stripe billing, and delivered a privacy-focused multi-profile browser application with encrypted session storage and Playwright end-to-end coverage.

I delivered bKash, Nagad, and Rocket fintech payment integrations that processed more than 10,000 monthly transactions. These integrations automated reconciliation workflows and reduced the need for manual intervention by finance teams.

I architected modular backend services for healthcare and rental-management products, with clear API boundaries that enabled independent product evolution. I containerized applications with Docker, deployed them on AWS EC2 through CI/CD pipelines, and collaborated with a distributed Agile team using code reviews, pull requests, and written documentation.

I developed REST and GraphQL APIs using NestJS, including authentication and validation layers that improved reliability for a live enterprise application. I also engineered Socket.IO-based real-time communication features to support low-latency, interactive product experiences.

I automated GA4 analytics tracking across the product funnel, giving the team actionable visibility into user behavior and drop-off points. This data supported product decisions and helped identify opportunities to improve conversion flows.

I built and maintained React.js and Next.js applications, creating a reusable component library that reduced duplicate user-interface code across product features. I contributed to consistent, maintainable frontend implementation across the application.

I improved frontend performance through code splitting and lazy loading, helping reduce page-load time and improve user experience. I worked on delivering responsive interfaces and reusable frontend architecture.
