Jacob Heijligers is a contract software engineer with a master's from TU Delft and 11 years of hands-on experience shipping high-complexity systems end-to-end. He specializes in fast, autonomous delivery across backend, infrastructure, and mobile/web stacks—recently tackling advanced Rust challenges for RL research at a stealth AI startup. Jacob has a track record of solving adversarial and scaling problems, from a distributed, Kubernetes-backed chatbot used by millions to a Rust-powered data pipeline that modernized a real estate platform while working part-time. Comfortable both as a solo engineer and a collaborator, he prioritizes clarity, speed, and maintainable architecture to turn ambiguous problems into production systems. Outside client work he prototypes tools to explore new ideas or improve daily life, reflecting a bias toward creative, pragmatic engineering.
