Python Developer and AI Engineer with 2+ years of combined experience in AI/ML engineering and teaching. I build production AI systems around LLMs, RAG, NLP, and multilingual AI — reducing inference latency, fine-tuning with LoRA, and crafting scalable Python backends.
I've mentored 100+ students in data science and ML, and now I ship AI at M7 Corporation — optimizing models, deploying RAG pipelines, and building multilingual chatbots for real-world impact.
End-to-end Tamil/English complaint-management chatbot using RAG, vector search, and LLMs with location validation, voice input, and live-agent fallback.
AI image QC pipeline (SQS → Lambda → Gemini) scoring blur/darkness/quality, and automated donor-deliverable generation on Lambda + Cloudflare R2.
LightGBM quantile-regression model (P50/P80) predicting photo-delivery time across 66 categories on ~950K records with leakage-safe features.
Custom Tamil tokenizer and fine-tuned generative audio models for regional-language music generation using LoRA.
Python CLI to connect, send, and automate WhatsApp messaging with pluggable providers, event/storage layers, media handling, and AI skills.
Extracted structured text from scanned PDFs, handwritten content, and non-standard fonts for downstream AI processing.
Python CLI that turns a YAML spec into a populated SQLite/PostgreSQL database and auto-generates a FastAPI CRUD server with pagination, filtering, sorting, and relation resolution — plus a bottom-up schema-validation layer and pluggable database backends (factory pattern).
