Profile: https://flows.cv/jenniferuvia

Applied ML engineer with 10+ years of engineering experience, including search and ranking systems (Pinterest, Thumbtack). I’ve worked on end-to-end model updates (including GBDT and neural network retraining) with a focus on evaluation rigor, ML fairness efforts, and production reliability.

I’m known for raising quality bars, improving on-call and engineering processes, and bringing calm, structured leadership to high-stakes environments. I care deeply about building teams where clarity, trust, and psychological safety enable strong technical outcomes.
