Summary
👤
Senior🎓
Top SchoolKrzysztof Ksiazek is an expert MySQL/MariaDB consultant and founder with over a decade of hands-on experience designing high-availability database architectures, running remote DBA services, and performing deep performance audits. He has led support and professional services teams at Severalnines and provided DB expertise to high-profile customers through roles at Blackbird.io and PalominoDB, translating complex replication and clustering challenges into reliable production systems. Comfortable with proxy tiers (ProxySQL, MaxScale, HAProxy) and cluster technologies (Galera, Percona XtraDB), he blends architecture design with practical day-to-day operations and POC delivery. Based in Madeira, Portugal, he pairs formal engineering training with a long history of compiling custom MySQL distributions and troubleshooting subtle, hard-to-reproduce issues—an indicator of both low-level technical depth and operational pragmatism.
