Philip Stanislaus is a founder and technical leader with a decade of hands-on experience building secure, blockchain and backend systems from prototype to production. Based in Germany, he has held roles from blockchain architect at Snowfork to managing director of Oak Security and recently founded Causa Prima, blending deep security research with applied blockchain engineering. His open-source contributions include meaningful backend work on prominent projects like Flow (onflow/flow-go) and the Go Substrate RPC client, where he focused on performance, codec implementations, testing and metrics. Comfortable moving between low-level protocol work and product-facing startups, he pairs an economics and finance-informed Cambridge/TUM background with practical full-stack engineering and a track record of founding and scaling technical ventures.
