Summary
👤
Senior🎓
Top SchoolViacheslav Kovalev is a Machine Learning Engineer with 11 years of engineering experience who blends production-grade backend skills (Python, FastAPI, Docker, Postgres) with strong applied ML expertise (CatBoost, LightGBM, PyTorch, transformers). He has shipped recommender systems and RAG/S2T knowledge pipelines—building a FastAPI-based post recommendation service that leverages DistilBERT embeddings and A/B testing to drive measurable improvements. At Carlsberg he boosted forecast accuracy by 15% through time-series modeling and SQL optimization, and at UPlineSoft he engineered asynchronous VK bots, Prometheus metrics, and S3-integrated pipelines for real-world deployment. He also contributes to open-source tooling, improving profile management and dependency handling in the widely used Erlang rebar3 project. Comfortable moving between feature engineering, model tuning (Optuna) and infra concerns, he brings a pragmatic, data-oriented approach shaped by both ML internships and earlier engineering roles in petrochemical process optimization.
