Senior Software Engineer @ PayPal | Go · Java · FastAPI · MCP · RAG · Distributed Systems

About

Currently Senior Software Engineer at PayPal with total 8 years of experience, working in Go, Java and BigQuery on distributed payment systems. These days most of my attention goes to the other side of the same problem — agentic AI in production. MCP servers, RAG pipelines, LLM workflows on FastAPI. Built with distributed-systems, because that's what they are: retries, idempotency, observability, graceful degradation. An agent that fails silently is more dangerous than one that fails loudly.
