Top SchoolMike Nelson is a seasoned engineering leader with 11 years of experience building and scaling product and platform teams, currently focused on retirement engineering at Gusto after a decade as CTO at Guideline where he helped build a full-featured, low-cost 401(k) stack. He combines hands-on backend expertise—evidenced by refactoring and performance work on Instacart’s makara read-write DB proxy—with product-minded architecture from roles at TaskRabbit and earlier startups he helped found or sell. Based in Portland, Maine, he’s comfortable across the stack and lifecycle: shipping mobile apps, web services, and developer-facing libraries while leading teams. A pragmatic problem-solver and lifelong tinkerer, he brings entrepreneurial instincts and a mechanical-engineering-rooted attention to systems and reliability.
