AI Engineer at Tata Consultancy Services, Chennai, India.

I build AI application components for production enterprise RAG and backend integrations. My RAG work covers retrieval, prompts, grounding checks, guardrails and evaluation using LangChain, Gemini and Vertex AI Vector Search. My contribution is the AI application layer, not cloud infrastructure or operations ownership.

I also build Java and Spring Boot modules with Kafka for production data migration and synchronization, and work on regression validation for migration releases. My ticket-assistance work is a prototype, with classification, similar-case retrieval and human review.

A local data investigation workbench with tool-calling agents, schema inspection, validated read-only SQL, evidence-backed charts and dashboards. Built with Python, FastAPI, Next.js and MCP. Uses step and tool-call limits and explicit approval before MCP calls. The current README records 30 Python tests. Test counts do not establish SQL accuracy, agent task success or adoption.

A Python runtime that executes eligible read-only tool calls while generation streams, then replays the final script from a fresh namespace and reuses exact cache hits. A local simulated benchmark on independent calls measured 764 ms to 368 ms median latency, a 51.8% reduction. This is not a production performance claim.

Snapshot: 5 Oct 2026. GitHub language-byte shares are normalized inside each public, non-fork repository with detected code, then averaged with equal repository weight (23 repos). Repositories without detected code are excluded. This chart describes code composition, not skill or proficiency. Other includes HTML, JavaScript and Shell. Bars are static until regenerated.
