Frontend Engineer @ PipeTech Software
Full-stack product engineer — React & Next.js on the front;
NestJS, MongoDB, and AWS in production at PipeTech.
📍 Grand Haven, Michigan · Personal: JamesWJager · Work: James-Jager
I'm driven by clean code, clever systems, and hard problems worth solving.
I care about type-safe contracts (Zod, DTOs), polished React/Next.js UIs, and full-stack delivery
where design meets solid NestJS APIs and MongoDB data layers.
