🤩
RockstarDaniel Black is a Chief Innovation Officer with 16 years of experience specializing in databases, DevOps automation, and cross-platform reliability, currently leading innovation at the MariaDB Foundation from Canberra. He combines hands-on backend engineering with infrastructure and CI/CD expertise, contributing to high-profile open-source projects like MariaDB Docker images, RocksDB, SQLAlchemy, and Compiler Explorer. His work spans database internals, connector compatibility (including Solaris/FreeBSD fixes), authentication enhancements in PyMySQL, and performance-focused tooling such as MySQLTuner. Daniel has a strong track record of improving build pipelines, multi-architecture Docker deployments, and test automation to make complex systems more robust and portable. Colleagues rely on him to refactor brittle startup/config flows and remove subtle runtime issues—skills he honed earlier as a POWER performance engineer at IBM. He’s a serial (and occasionally parallel) open-source coder who prefers practical fixes that prevent future headaches rather than flashy one-off features.
