Summary
👤
Senior🎓
Top SchoolAlex K is a Senior Software Engineer with 16 years’ experience building full-stack web applications, currently shaping developer experiences at StackBlitz after a senior backend tenure at GitLab. He moves fluidly between languages and layers—from Haskell microservices and REST APIs to client-side single-page apps—and has repeatedly engineered features that became key product differentiators. Notable contributions include performance-focused core work on the InterMine data warehouse and enhancements to the widely used GitLab Go SDK and GitLab CE codebase. He brings a pragmatic blend of API design, data-processing optimization, and testing discipline, and has a track record of delivering both deeply technical refactors and user-facing improvements. Based in Portland, Maine, he pairs an uncommon humanities background (MSt, Classics) with rigorous engineering, lending him strong design sensibilities and clear technical communication.
