About

CSE undergrad at SRM University AP ('28), working at the intersection of backend systems, AI agent infrastructure, and scalable architecture. Currently independent — actively building projects, exploring system design in depth, and open to internship and collaboration opportunities.

My work gravitates toward:

  • Designing backend systems with attention to scalability, observability, and clean API contracts
  • Building AI-native tooling — agents, MCP servers, LLM inference pipelines
  • Exploring distributed systems patterns: event-driven design, concurrency, and fault tolerance
  • Writing production-quality code with emphasis on maintainability and architectural clarity
  • Balancing active DSA practice alongside development — strengthening the algorithmic foundation that underpins good system design

Tech Stack

Languages

C C++ Python JavaScript TypeScript

System Design Focus

Areas I actively study and build toward:

  • API Design — REST conventions, versioning, contract-first development
  • Distributed Systems — consistency models, event-driven patterns, message queues
  • Database Architecture — schema design, indexing strategies, query optimization
  • AI Agent Infrastructure — tool-use pipelines, MCP protocol, LLM orchestration
  • Observability — logging, tracing, and monitoring in production systems

Open to internships and collaboration — reach out via email or LinkedIn.
