Message

At vThink Global, I own backend services for production multi-agent AI platforms, including orchestrators for Investment Readiness and Investment Council. I migrated agent services from AutoGen to LangChain and LangGraph, built production RAG on PostgreSQL with pgvector, and created a read-only MCP server for Databricks lakehouse data.

At Tata Consultancy Services, I spent six years as Lead Analytics Engineer for Kongsberg Maritime, building a Snowflake telemetry platform for autonomous-vessel development. I developed ETL pipelines and dbt models, orchestrated workflows with Airflow on Kubernetes in AWS, and built data marts and governance capabilities. Earlier, I built a C#/.NET automation tool with estimated annual savings of USD 110K.
