What I'm looking for

I'm looking for Backend Engineer or SDE-2 opportunities focused on scalable systems, distributed architectures, and challenging backend problems.

At VCBay, I build search and retrieval workflows across 2.7M+ startups and 3M+ investors, combining structured filters, Pinecone semantic search, and MongoDB profile retrieval. I also create Redis- and BullMQ-powered background workflows and caching for high-traffic APIs.

Previously at ZFIN TECH, I shipped 10+ RESTful APIs, improved critical endpoint latency by 20%, optimized database queries with indexing and profiling, and integrated payment, KYC, and SMS services with retry logic.
