Full-Stack Software Engineer

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

I architected a marketing attribution and tracking platform using RabbitMQ for event-based data collection, campaign-source 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 fintech payment integrations for bKash, Nagad, and Rocket, processing more than 10,000 monthly transactions. These integrations automated reconciliation processes and removed the need for manual finance-team intervention.

I architected modular backend services for healthcare and rental-management products, creating isolated API boundaries that allowed products to evolve independently. I containerized applications with Docker, deployed them to AWS EC2 through CI/CD automation, and collaborated with a distributed Agile team through code reviews, pull requests, and written documentation.

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

I automated Google Analytics 4 tracking across the product funnel, providing visibility into user behavior and drop-off points. This data enabled the team to make more informed product and conversion optimization decisions.

I built and maintained React.js and Next.js applications, creating reusable components and a component library that reduced duplicate UI code across product features. My work supported more consistent user interfaces and faster feature delivery.

I improved frontend performance through code splitting and lazy loading. These optimizations improved page-load speed and strengthened the overall user experience.
