Senior🎓
Top SchoolMark Hofmann is a seasoned Java and Kotlin backend developer, architect, and consultant with over two decades of professional experience and 11 years focused on modern backend architectures. He has co-founded multiple startups and served as CTO, repeatedly bridging product needs and scalable technical designs—from monolith refactors to microservice, Kubernetes and AWS-based systems. Comfortable in both small creative agencies and larger teams, he favors remote, location-independent engagements and is open to early-stage technical consulting or interim CTO/co-founder roles. His hands-on toolkit spans Spring, Vert.x, RxJava, JOOQ, PostgreSQL, MongoDB, Elasticsearch, Terraform, and CI/CD automation, reflecting deep operational experience running production services. Notably, he has built domain-specific products (e.g., veterinary diagnostic apps and transport routing microservices) and enjoys working with experimental stacks like Scrypto. Based in Berlin with long European and SEA ties, he combines pragmatic engineering with startup hustle and a willingness to work with constrained budgets.
