Web platforms that stay maintainable after launch
From 2015 I help companies and teams when a WordPress site, Craft CMS build, online store or Linux environment starts limiting further work. I combine application code, caching, integrations and infrastructure to find the source of a problem and implement a change that remains maintainable.
Most of my work involves stabilising existing platforms, performance, e-commerce development and focused plugins or automation.

These case studies show work on real constraints: production caching, document generation, asset versioning, image optimisation and e-commerce. Each one explains the problem, scope and technical approach.

A Few Things I Have Learned Along the Way
💠 I've been programming for over 11 Years . I started with websites, PHP, and JavaScript. Over time, I've added online stores, Craft CMS, WordPress, Linux servers, and DevOps.
💠 I enjoy projects that require me to delve deeper than just the website's appearance. Sometimes the problem lies in the code, sometimes in the database, cache, integration, or server configuration.
💠 After hours, I also develop open-source projects related to Craft CMS and Android. It's from these projects that I gain the most practical knowledge.
Notes from technical work
I publish practical notes from WordPress, Craft CMS, Varnish, cache and infrastructure work, including diagnosis, limitations and verification steps.
