Rockstar🎓
Top SchoolJesse Gumm is a pragmatic software engineer and founder with 15+ years building web products, from bootstrapped startups to an acquisition by SportsEngine. He’s the creator of BracketPal and owner of Sigma Star Systems, and has deep backend expertise in Erlang—contributing to notable open-source projects like Nitrogen, ChicagoBoss, and BossDB. Comfortable shipping solo, Jesse pairs hands-on development with product ownership, having managed BracketPal’s roadmap and implementation post-acquisition. His background includes long experience with PHP and JavaScript, database work across MySQL/Postgres, and practical cross-platform build tooling. Colleagues would note his knack for “scratching programming itches”: finding targeted, stability-focused fixes in core frameworks rather than flashy rewrites.
