I independently built Violet Feathers, an AI-native learning management system with multi-agent tutoring, secure code execution, role-based learning workflows, and production deployment.

I designed Tutor, Hint, Explain, Debug, and Code Evaluation agents using intent routing, contextual prompts, RAG, multi-model fallbacks, retries, and rate-limit handling. I also engineered an asynchronous coding-assessment pipeline with FastAPI, Redis, Celery, and isolated Docker execution.

I'm building the Cognitive Knowledge Platform, a provenance-first Cognitive RAG system for grounded, syllabus-aligned MCQ assessments from Tamil Nadu State Board textbooks. Its backend uses FastAPI, PostgreSQL, Redis, Alembic, Docker Compose, vector retrieval, and automated tests.

Previously, I built AI assistant, semantic recommendation, and RAG pipelines at KAT Enterprise LLC, and AWS image-recognition workflows at Mukesh and Associates. I bring Python, FastAPI, Next.js, PostgreSQL, Redis, Docker, cloud deployment, and a systems-first focus on reliability, safety, evaluation, and latency.
