What I'm looking for

I'm looking to build recommendation systems and NLP products where I can improve measurable online and offline metrics, automate ML workflows, and run A/B tests.

At Tevenix, I built and developed ML services, ranking algorithms, and multi-stage recommendation systems for e-commerce and marketing.

I reduced influencer selection from 2–3 days to 15 minutes using CatBoost scoring, FAISS retrieval, and CatBoost LTR re-ranking. The system increased advertising integration conversion by 18% and automated up to 75% of inbound blogger-manager responses.

I also built recommendation modules for an online retailer and RAG assistant, raising CTR by 23% and add-to-cart conversion by 15% in A/B tests. I work primarily with Python, PyTorch, CatBoost, BERT, FAISS, FastAPI, ClickHouse, and PostgreSQL.
