AI, ML & Web Application Developer
B.Tech Artificial Intelligence & Machine Learning student building AI-powered applications end to end: retrieval pipelines, model integration, async APIs, database design, and containerized deployment.
Built a full-stack RAG assistant and a reliability auditor for AI agent workflows, both covered by automated tests in CI.
Eager to contribute to live AI, data, and automation projects.
Coimbatore, Tamil Nadu, India
A full-stack assistant answering programming questions from official documentation and indexed GitHub repositories. Answers cite their exact source to reduce hallucinations.
LangChain, sentence-transformer embeddings, and FAISS/ChromaDB storage power hybrid dense + BM25 retrieval. A cross-encoder reranker supports semantic code search and stack-trace debugging.
Async FastAPI backend with PostgreSQL, Redis, API-key authentication, rate limiting, and health probes. Next.js + TypeScript UI, Docker Compose deployment, and CI gates.
Tools: Python, FastAPI, LangChain, FAISS/ChromaDB, PostgreSQL, Redis, Next.js, TypeScript, Docker, GitHub Actions
A zero-dependency Python CLI that crash-tests AI agent workflows performing real side effects. Records intent before execution and reconciles against external truth to report duplicate or lost effects.
SQLite WAL and synchronous=FULL underpin idempotency and recovery, with cross-process leases, dead-holder reclamation, three replay policies, and process-death fault injection.
Property-based and concurrency tests across Python 3.11-3.13 on Linux, macOS, and Windows in GitHub Actions. Maintained 90%+ coverage with strict mypy and ruff gates.
Tools: Python, SQLite, CLI tooling, pytest, Hypothesis, mypy, GitHub Actions
Python computer vision that automatically detects and tracks vehicles in aerial footage to analyze traffic flow.
Built and tested deep-learning object detection in reusable detection, tracking, and reporting modules. Automated the workflow to surface vehicle-flow insights for real-time decisions.
Detection workflows use RF-DETR and YOLOv8.
