During my time at Google, I worked as a Tech Lead / Manager on the Ranklab Machine Learning Platform, helping teams across Alphabet solve complex machine learning challenges and build scalable, production-ready ML solutions.
Ranklab evolved from an internal machine learning platform within Google Search into an end-to-end solution supporting data analysis, rapid experimentation, model training, evaluation, and production serving.
My work focused on leading ML engagements, collaborating with engineering and product teams, and developing models that balanced predictive performance with interpretability, maintainability, and long-term reliability.
The platform enabled teams to accelerate model development, streamline experimentation, and integrate machine learning capabilities into their products more efficiently.
Key areas: Machine Learning, Python, Model Training, Feature Engineering, Distributed Systems, ML Infrastructure, Model Serving, and MLOps.
