What I'm looking for

I'm looking to build backend, real-time, cloud-native, and AI/LLM-integrated products where I can own end-to-end delivery and solve production-scale problems.

I've built and maintained scalable healthcare, fitness, travel, booking, and e-commerce applications at Praxus, Beeline / Brevity Software, Misha Technologies, and MetaTree Pvt. Ltd. My work includes high-performance REST APIs, AWS serverless solutions, secure PayPal and SagePay integrations, and production environment support.

I also build hands-on AI and real-time systems, including a live GitHub-event RAG platform that achieved 26.6ms average latency across 5,130 queries, a self-hosted multimodal document assistant, and messaging platforms in both ASP.NET Core/SignalR and Flask/Socket.IO.
