Backend & Infrastructure Architect | Scalable systems, API ecosystems & high-load platforms

About
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.
Available for
Available for backend and system-level work, including CMS and WordPress development (custom plugins, themes, and large-scale implementations), API design and integrations, authentication flows (SSO), and performance optimization. Experienced with complex integrations and services such as CDN setups, email automation platforms (InfusionSoft, aWeber, MailChimp), and communication systems (Twilio). Focus is on building stable, efficient, and production-ready systems.
