I build scalable data platforms, OpenSearch systems, and AI agents that cut costs and improve retention.
BangladeshWhat I'm looking for
At Goava Sales Intelligence, I build production data platforms, search infrastructure, and AI-powered workflows at scale.
I re-architected an OpenSearch cluster to cut AWS costs by 43%, reduced sync time by 200 ms, and lowered storage costs by 22% through LLM-based false-positive news detection.
I built an LLM-based profile enrichment system that added 15+ dimensions per profile, helped lift customer retention by 7%, and improved contact coverage from 75% to 95%. I also built an MCP server for querying and actioning company data from Claude and ChatGPT, reducing manual effort by 98%.
Previously, I architected an indexing pipeline processing 10M+ records daily across 300M+ OpenSearch documents and built data-collection spiders handling 25k job postings per day.
