Backend architect with 20+ years of experience working with PHP, APIs, and high-load systems. I focus on real-world performance, system architecture, and fixing problems that show up only in production - slow APIs, scaling issues, unstable integrations, and legacy code that blocks growth. A big part of my work is WordPress at scale, custom backend systems, and building lightweight, efficient solutions (including my own PHP framework). Here I write about performance, architecture, and practical problem-solving - no theory, just things that actually matter when systems are under load.
