Hello!
I am Logesh Kumar Umapathi , a Machine learning Engineer at Blackbox.ai. My work focuses on building agentic systems and models that help in automating software development and improve developer productivity. My interests include Code generation LLMs , Synthetic data generation with LLMs and Alighnment of code LLMs to Human preferences.
Previously, I was a Lead Maching learning Engineer at Saama Technologies. Leading machine learning efforts for a product focused on accelerating clinical trials and time to market of drugs.
I have been part of notable Code LLM research including Starcoder , Santacoder and Bigcode Evaluation harness.
When I’m not in front of a computer screen , I would love to speak at ML events. I also love reading books and photography.
