About

I am an engineer with 13+ years building Python and distributed systems across fintech, smart city, and property management platforms, now focused on AI. I work in two directions: building AI and LLM systems end to end — RAG services, transcription pipelines, and multi-model generation workflows — and AI-assisted development, using agentic coding and workflow automation to design, build, and ship software faster and more reliably. Currently Senior Technical Lead at Fcode Labs; open to senior and architecture roles, and available for freelance AI and backend engineering.

Selected projects

• Lecture Transcription & Exam Prep Platform — 100+ recorded lectures turned into an interactive study site, powered by a Modal + faster-whisper pipeline. See projects.
• Domain Q&A Service (RAG) — a FastAPI RAG service over a multilingual, LLM-translated corpus, powering Q&A inside a mobile app. See projects.
• Adaptive Tamil Literacy Tutor — an offline-first PWA that models what a learner knows (Bayesian Knowledge Tracing + spaced repetition) and adapts every session. See projects.
• AI Cartoon Generator — a multi-model pipeline turning characters and a theme into an 8–10 minute animated video. See projects.
• Self-Hosted Health Ledger — a private health tracker with vision-model food-photo estimation and LLM lab-report ingestion. See projects.
• DSA Coach — a zero-dependency spaced-repetition practice scheduler running as a private systemd service. See projects.
