Sergio Pérez is a pragmatic Head of Engineering with 10 years of experience spanning startups to multinationals, blending deep frontend roots with fullstack and backend fluency. He leads product-oriented teams as a Team Lead and Engineering Manager, applying eXtreme Programming and Lean build-measure-learn principles to accelerate delivery and maximize impact. A relentless feedback seeker, he leverages TDD, CI, monitoring, user metrics and structured 1:1s to continuously improve code, systems and team health. Sergio partners closely with PMs and PDs to translate product goals into achievable plans, balancing “how, who and when” with strong context on implementation trade-offs. Known for moving fast without sacrificing quality, he also brings a curious, data-minded streak—treating both product experiments and his own fitness as iterative systems to optimize.
