Full-Stack Software Engineer

Leading full-stack engineering for a marketing and sales technology suite, owning everything from database design to production deployment.

• Built the backend for a proxy infrastructure reselling service (NestJS, GraphQL, PostgreSQL) with supplier API integration and sticky-session IP routing.
• Delivered a privacy-focused multi-profile browser app with isolated fingerprints and encrypted session storage.

Built fintech and backend systems for a fully remote, distributed engineering team spanning multiple time zones.

• Delivered fintech payment integrations for bKash, Nagad, and Rocket processing 10k+ monthly transactions, automating reconciliation and removing manual finance-team work.
• Architected modular backend services for healthcare and rental-management products, isolating API boundaries so each product could evolve independently.
• Containerized applications with Docker and deployed to AWS EC2, automating releases through CI/CD and replacing manual, multi-step deployments with a single repeatable pipeline.
• Collaborated async across a distributed, Agile team through structured code review and written documentation instead of real-time meetings.

Built backend APIs and real-time features for a production enterprise application.

• Delivered REST and GraphQL APIs in NestJS with authentication and validation layers, strengthening reliability for a live enterprise application.
• Engineered Socket.IO-based real-time communication features, enabling low-latency updates for interactive product experiences.

Built and optimized React.js/Next.js applications early in my full-stack career.
• Built and maintained React.js/Next.js applications, establishing a reusable component library that cut duplicate UI code across features.
• Optimized frontend performance through code-splitting and lazy loading, measurably improving page-load speed and user experience.
