I've built backend systems for DoubtSolve, a real-time academic Q&A platform, owning business logic, data models, and 47 REST API endpoints with Node.js, PostgreSQL, and Prisma.
I designed its six-container Docker Compose architecture and Kafka event pipeline for real-time notifications, while implementing Redis rate limiting, JWT blacklisting, RBAC checks, search, and image-upload validation.
For a Flight Data Management Service, I developed a C++17 REST microservice that consumes the OpenSky Network API and exposes six custom HTTP endpoints. I separated API integration, business logic, and server layers using object-oriented design, design patterns, and SOA principles.
I've also engineered DreamHome, a multi-role rental management platform, and solved 350+ data structures and algorithms problems across LeetCode and CodeChef.
