I'm building and enhancing enterprise web applications at Kent RO Systems using C#, ASP.NET Core, Node.js, Express.js, React.js, and React Native. My work spans REST APIs, backend modules, database integrations, business logic, and responsive frontend components.

I've built JashanTantra, a scalable event-management backend using NestJS microservices, PostgreSQL, and RabbitMQ-based asynchronous communication. I also developed a production-oriented URL shortener with JWT authentication, Redis rate limiting, and deployment on AWS EC2 with Nginx and PM2.

For Aethal Financial AI, I created a financial information assistant using Python, FastAPI, RAG, Qdrant, LangChain, semantic search, vector retrieval, and embedding models.

My project work also includes PollFirst, a political survey and analytics platform with secure REST APIs, interactive dashboards, and automated news and election data collection.
