About

I'm a Computer Science undergraduate at SRM University AP (Class of 2028) focused on software engineering, backend systems, full-stack development, and system design.

I recently completed a Product Engineering Internship at CCC Digital, gaining hands-on experience building software around Agentic AI and LLM-powered workflows.

My primary focus is building reliable, maintainable software — from designing APIs and data models to developing full-stack applications, optimizing performance, and deploying production-oriented systems.

I enjoy solving engineering problems involving data structures and algorithms, backend architecture, distributed systems, databases, APIs, concurrency, performance optimization, and developer tooling.

Alongside core software engineering, I work with LLMs, AI agents, RAG pipelines, and MCP to explore how AI can be integrated into real-world software systems.
