Rockstar🎓
Top SchoolStephen Altamirano is a versatile senior software engineer with 15 years' experience building backend systems and developer tools from startups to scale-ups in the Bay Area. He has shipped services at Square and led engineering at Patreon, combining hands-on coding in Python, JavaScript, PHP, Lua and Haskell with production experience across MySQL, Redis, MongoDB and AWS. A practical polyglot, he contributes to notable open-source tooling like mitmproxy—adding content-encoding support and UX improvements for inspecting compressed HTTP traffic. His background in physics (Stanford) and an early research stint in nanophotonics reflect a curiosity for low-level systems and complex problem solving. Colleagues rely on him to bridge engineering leadership and deep technical execution, especially when systems require careful protocol handling and performance-minded design.
