Summary
👤
Senior🎓
Top SchoolJohn Kernke is a seasoned web developer with 13 years of experience building fast, pragmatic front- and back-end solutions using PHP, JavaScript, CSS and MySQL, and a growing interest in Node.js and Python. He has a track record of taking concepts to working prototypes quickly and improving performance at scale—examples include speeding WordPress and bespoke datacenter systems from painfully slow to sub-second responses. His background spans startups, freelance engagements and in-house systems for a 3,000-client datacenter, where he contributed to a million-line management codebase and built shopping carts, rack management and custom tooling. Equally comfortable in server configuration (Apache, IIS), caching strategies and client-side polishing, he blends practical engineering with product-minded consulting for CEOs and small teams. Based in Brisbane, he brings both hands-on execution and a history of measurable impact—350k+ downloads from early Messenger extensions and notable page-speed gains—showing a focus on user experience and operational efficiency.
