Machine & Deep Learning

Training and deploying ML/DL models with PyTorch and Hugging Face for real applications.

👁️

Computer Vision

Object detection & recognition — YOLO, ST-GCN, OpenCV on both server and edge devices.

💬

LLM & RAG Systems

Retrieval-augmented chatbots and agents with LangChain, Gemini API, MongoDB and Chroma vector DB.

What I Do

My Awesome Services

I focus on turning AI research into products that work in the real world — from data preprocessing and model training to deployment on servers and embedded hardware.

Comfortable across the stack: Python, C++, C#, PyTorch, Hugging Face, OpenCV, Streamlit, LangChain, MongoDB and Microsoft SQL.
