Senior🎓
Top SchoolMarcin Kosecki is a Senior Data Scientist and machine learning engineer with nearly eight years of hands-on experience building production-grade NLP and TTS systems, from dialogue managers and voice cloning to image synthesis and storytelling pipelines. He has led and grown teams at AI startups, managing up to seven engineers while still contributing deep technical work—designing information extraction for financial docs, building RAG-enabled services, and deploying vocoders and inference APIs. His background includes enterprise-scale projects at Samsung, where he developed noise-robust dialog managers and multilingual keyboard models with CI/CD for model validation. Marcin blends research-minded experimentation (exploring autoregressive speech token methods and transformer variants) with pragmatic MLOps and distributed systems skills across Python, PyTorch, Hugging Face, AWS, and message-queue architectures. Based in Warsaw, he is a quick learner who pairs technical leadership with hands-on model development and a track record of turning POCs into deployable services.
