👤
SeniorMartijn De Haan is a pragmatic full-stack engineer and founder with 12+ years of experience building scalable microservices, snappy front-ends and native mobile apps for clients like Tommy Hilfiger, Heineken, Randstad and South Pole. He blends hands-on coding (Node.js, TypeScript, Java, Go, React/React Native, Swift/Objective‑C) with cloud-native infrastructure expertise across AWS and GCP, Terraform and event-driven architectures. Martijn helps teams adopt lean development, feature flagging and SRE practices to deliver measurable value in days rather than quarters. He has founded and led multiple product and platform efforts—from a feature-toggle service to proptech ventures—and regularly performs technical due diligence. Based in Amsterdam, he’s soon available for new engagements and often pairs pragmatic engineering with product intuition to de-risk early experiments.
