About Me

I'm a Module Lead at Mphasis, previously a Technical Lead at Wipro on Bank of America engagements, with 11+ years of experience designing and building enterprise applications across banking, telecom, travel and hardware domains.

My core is Java backend engineering — Spring Boot, microservices, Hibernate, RESTful APIs — backed by CI/CD with Jenkins, Docker and Kubernetes, and solid database work on Oracle, MySQL and PostgreSQL.

Today I combine that foundation with Generative AI: building agentic workflows with LangGraph, LangChain and CrewAI, RAG pipelines over enterprise data, and AI-driven apps with OpenAI, FastAPI and Streamlit.

AI-Powered Weekly Review & Meeting Governance Platform

An enterprise AI-assisted review platform that replaces manual Excel verification in weekly team meetings with a single, auditable, AI-driven workflow.

RAG over Excel

Data intelligence layer that retrieves the right information from multi-tab Excel files for the current review period.

One-click AI verdict

Validates all weekly requirements and returns a clear call: Good to Proceed or Pending Items Detected.

LangGraph workflows

Step-by-step validation with human-in-the-loop decision gates for critical missing data.

Governance & audit

Lead override with mandatory feedback — accountability without blocking the meeting.

Prompt-as-configuration

Full CRUD for prompts so admins can change validation logic without code changes.

Automated reports

End-to-end meeting reports with validation summaries, pending items, lead comments and action plans.
