Senior🎓
Top SchoolMatthew Stevens is a freelance software engineer based in Berlin with 12 years of experience delivering full-stack and distributed systems for startups and enterprise clients. He specializes in RESTful APIs, Dockerized microservices, database design, React web clients, and CI/CD plus pragmatic DevOps for cloud deployment and monitoring. Matthew has deep hands-on experience in blockchain tooling and smart contract ecosystems—designing audited contracts, on-chain indexing and monitoring, and integrating NFT marketplaces and preventative/reactive safety services. He regularly joins early-stage teams to turn prototypes into production-ready platforms, having led architecture, data modeling, and surge-ready systems for projects like Zalando’s loyalty service and multiple crypto-native products. Comfortable both on-site in Berlin and remote, he also mentors engineers on secure smart contract practices and scalable engineering patterns. Beyond code, he tends to build tooling that bridges services (e.g., auto-generated clients, Kafka validation libraries, and indexing services) that make complex systems auditable and maintainable.
