🧭 About Me

"I build systems that are correct, secure, and pleasant to maintain — then teach them to think."

I'm a backend-focused engineer who enjoys turning complex problems into clean, scalable systems — and increasingly, into systems that reason. My core stack is Java and Spring Boot, but I spend just as much time in the AI/LLM space: building retrieval-augmented pipelines, working with vector databases, and running local inference so intelligence doesn't have to come at the cost of privacy or cloud spend.


🎓 Education B.E. Computer Engineering, SPPU — 4th Year · CGPA 8.59
💼 Focus Java · Spring Boot · REST APIs · Distributed Systems
🧠 Also into RAG pipelines · pgvector · Local LLM inference (Ollama)
📌 Status Actively seeking SDE / Java Backend Developer internships

🎯 Currently Building

+ Local-first AI/RAG systems (Spring Boot + pgvector)
+ Secure, JWT-protected multi-tenant REST APIs
+ Backend systems modeled on real financial workflows

📚 Currently Learning

! Spring Security — deep dive
! Docker & containerized deployments
! System Design at scale
