About Me

Full-stack engineer passionate about building AI systems that solve real problems

Professional Journey

I'm a full-stack engineer with expertise across the entire technology stack. My career spans from high-frequency fintech systems to real-time video streaming, enterprise CRM/ERP solutions, and now cutting-edge AI/agentic platforms.

At Light & Wonder, I architect AI Harness Studio—an internal platform for testing and versioning LLM-powered features. I design and implement MCP (Model Context Protocol) server integrations for intelligent browser automation and system control.

I'm building an independent consulting practice targeting ₹80–120k/month revenue, developing MCP products with ambitions for 1,000+ users by Jan 2027.
