WordPress Engineer & Tech Lead
I'm Valerii — a senior WordPress engineer and technology leader based in Valencia, Spain. I help companies ship robust custom plugins, high-performance WooCommerce stores, scalable WordPress architectures, and AI-powered workflows that stand up in production.
Featured Work
A selection of projects across enterprise, open source, and agency work.
Open Source
A WordPress plugin that introduces a structured Abilities API for registering, categorizing, and exposing application capabilities via a REST endpoint. Designed for use in complex plugin ecosystems needing fine-grained permission introspection.
Enterprise
Built an advanced WooCommerce-based e-commerce platform for AWTG Ltd incorporating gamification mechanics — loyalty points, badges, and achievement systems — to drive user engagement and repeat purchases.
Performance
Led research and development of deep WordPress compatibility improvements for NitroPack's performance optimization plugin, focusing on caching layers, lazy loading, and server-side rendering strategies.
Client Reviews
4.96 average across 273 client reviews on Codeable.
Great communication, customer service skills and professional ability
Valeriy was prompt and thorough in responding to queries and completing the work
Valeriy delivered outstanding work on a highly complex WordPress performance project for us. Our website suffered from severe performance issues that several developers were unable to identify or resolve. Valeriy not only found the root causes within a very short time, he also implemented targeted optimizations that resulted in a dramatic performance improvement across all metrics, including LCP, TTFB and overall loading stability. What really stands out is his analytical approach and his ability to explain technical matters clearly. He documented every step, worked methodically, and always kept us up to date. The solutions he implemented were clean, scalable and fully in line with best practices. Communication was excellent. He responds quickly, works transparently and is extremely reliable. Even under time pressure he stayed focused and delivered above expectations. We will continue working with him on further performance fine tuning, structural optimizations and a security audit, because we trust his expertise completely. If you are looking for a developer who is both technically brilliant and highly professional in communication and execution, we can recommend Valeriy without reservation.
