Summary
👤
SeniorAlfredo Sumosa is a San Francisco–based software engineer with 8 years of experience building user-focused web applications across the full stack, from React and D3-driven front ends to Ruby on Rails and Node.js back ends. A former Electronics Engineer turned developer, he brings a hardware-minded attention to detail and systems thinking to software design and debugging. Alfredo is comfortable shipping under pressure, collaborating across teams, and maintaining data-driven interfaces using PostgreSQL, MongoDB, and RESTful APIs. He pairs practical product instincts with a love of clean UX, and maintains a public portfolio and GitHub with demos that showcase his penchant for interactive visualizations and polished web experiences. When not coding he’s exploring the city, sampling burgers, or reading—activities that feed his curiosity and keep his designs grounded in real-world use.
