What I'm looking for

I'm looking to build and deploy end-to-end AI solutions in computer vision, OCR, RAG, and LLM integration, with opportunities to work on real-time edge inference and scalable backend systems.

At TFRENZY Private Limited, I build real-time computer vision applications for PPE compliance, ANPR, and intelligent surveillance using YOLOv8, PyTorch, and OpenCV. I’ve optimized models with ONNX for efficient edge inference on NVIDIA Jetson Orin.

I built a RAG pipeline over a 4,300+ page medical corpus using PDF parsing, semantic chunking, FAISS, and LLM integration for contextual Q&A. I also collected and labelled a handwriting dataset, fine-tuned TrOCR, and developed an OCR-based visiting card digitization platform.

I work across AI delivery, from model training and video pipelines to Node.js REST APIs, MongoDB integration, and local speech transcription with whisper.cpp.
