B.Tech Computer Science student at VIT Chennai (CGPA: 8.71) specializing in software engineering, backend systems, machine learning, and Generative AI. Experienced in building scalable REST APIs, vector search pipelines, and cloud solutions.
Building intelligent systems,
not just interfaces.
I am a B.Tech Computer Science student at VIT Chennai with a passion for building production-grade software and AI systems. My experience bridges backend API engineering, vector search algorithms, and machine learning research.
During my internship at MentorKart, I optimized the AI Interview Portal by tuning prompt evaluation thresholds and developing scalable REST modules. Through Microsoft Elevate, I engineered cloud solutions on Microsoft Azure while deepening my focus on cloud security and AI infrastructure.
Whether designing zero-dependency semantic caches from first principles or engineering hybrid RAG search engines to eliminate LLM hallucinations, I approach engineering with a rigor for performance, reliability, and precision.

Semantic Search Analyzer
Vector Embeddings, GMM Clustering & First-Principles Semantic Caching
Built a scalable semantic search system over the 20 Newsgroups corpus using vector embeddings and GMM-based clustering, featuring a custom first-principles semantic cache.
Standard keyword search fails to capture contextual intent, while traditional in-memory caching solutions like Redis/Memcached require external dependency management and lack semantic similarity awareness.
Designed and deployed REST APIs using FastAPI for an end-to-end embedding → clustering → indexing pipeline, accompanied by a custom zero-dependency semantic cache built from first principles.
Hybrid Search RAG with Citation Verification
Built a hybrid RAG pipeline combining dense vector retrieval, BM25 sparse keyword search, cross-encoder reranking, and automated citation verification to reduce hallucinations.
