At Retouch4me & 3D LUT Creator (RELU OÜ), I built a mask refinement model using Uformer and global context to turn coarse segmentation masks into high-resolution masks with fine details and clean boundaries. Trained on real and synthetic data with weighted SWA, it reached Boundary IoU 0.9816.
I also implemented computer vision models from papers end to end in PyTorch and exported them to ONNX for ONNX Runtime inference.
As a freelance AI Engineer, I designed and built a Telegram AI assistant for a lighting manufacturer so staff could get luminaire specifications without asking engineers. It used the OpenAI Responses API for multi-step tool calling over structured product data, with source-row citations and Google Sheets syncing to SQLite.
At AI Strategy, I built and maintained APIs and Telegram bots with LLM and RAG integration. I shipped marketplace automation for Wildberries and Ozon sellers and a feedback bot for Territoriya Fitnessa, and implemented and trained AlphaGAN for natural image matting as a personal project.
