ABOUT

The Builder
Behind the Code.

I'm an AI Engineer currently at Entropik Technologies in Chennai, where I lead the backend development of real-time agentic AI moderation platforms. My work sits at the intersection of LLM orchestration, scalable Python backends, and production-grade AWS infrastructure.

Before Entropik, I built a full RAG platform at Infoware India — ingesting 10,000+ enterprise documents, integrating WhatsApp and voice-based LLM agents, and implementing memory layers for conversational continuity. I graduated from KIIT University, Bhubaneswar with a B.Tech in Computer Science.

Outside of work, I write about GenAI and backend systems on Hashnode, and I led Enactus KIIT as president — a 250-member entrepreneurship team that won India's National Cup and represented India at the World Cup in Kazakhstan. I'm a builder who writes, and a writer who builds.
