What I'm looking for

I’m looking for a team where I can build scalable event-driven backends, reliable data/search pipelines, and practical AI retrieval features—shipping measurable performance and reliability improvements in cloud environments.

I’m a Senior Software Engineer (SDE-2) at VISA Inc., where I architect event-driven, high-throughput payment and search systems. I decoupled payment processing from downstream search services using Kafka, eliminated backpressure, and delivered throughput up to 7,000 TPS, while serving 2.5M daily requests with sub-second retrieval.

I focus on reliability, scalability, and measurable impact—streaming transactions into MSSQL and Cassandra/Elasticsearch, enforcing consistency with proactive cache invalidation, and ensuring zero data loss via Dead Letter Topics and Avro schemas. I also build AI transaction search using multi-agent workflows with MCP, vector embeddings, and RAG-style retrieval so users can map ambiguous queries to precise transaction filters.
