Senior🎓
Top SchoolJohn Jensen is a Principal Software Developer in Seattle with eight years of experience leading full-stack teams to deliver high-performance consumer products spanning AAA games, mobile hits, and AI-powered web and native apps. He excels at marrying product thinking with agentic coding—building automation and tooling that shrink response times and boost team velocity, such as an LLM-driven sales harness that cut median response time from 72 to 12 hours. Comfortable across stacks (Next.js/React, React Native, Node, PostgreSQL) and platforms, he architects type-safe, end-to-end systems and performance-optimized UIs targeting 60 FPS. A hands-on leader, he manages cross-discipline teams, maintains CI/test infrastructure, and translates client needs into shipping features under shifting deadlines. His background in game systems and graphics gives him a pragmatic edge for performance and tooling, enabling fast iteration in product-focused environments.
