I'm Paul — a WooCommerce engineer and technical architect with 10+ years building the systems behind serious e-commerce businesses. I've scaled a health startup from $0 to $80M in annual revenue and maintained a WooCommerce platform doing $2M/month — not by hacking things together, but by building infrastructure that actually holds under pressure. Most of my clients aren't looking for a freelancer to knock out a task. They need someone who can look at the whole picture: the architecture, the integrations, the team, the roadmap — and make good decisions across all of it. That's the role I step into. WooCommerce is often where the conversation starts. Custom checkout flows, subscription systems, complex pricing logic, performance that doesn't fall apart under load — that's table stakes for me. But the more interesting work tends to be the layer underneath: internal tools, automation pipelines, bespoke business logic, and the kind of custom engineering that doesn't fit neatly into a plugin. What I actually work on: — WooCommerce architecture, custom plugin development, and platform builds that go well beyond off-the-shelf solutions. For high-traffic stores, that sometimes means the right call is moving critical logic — inventory, pricing, order processing — out of WordPress entirely and into dedicated NestJS microservices. WooCommerce stays as the storefront; the heavy lifting happens elsewhere. That's the kind of decision I'm here to make — Internal systems and business automation: tools your team actually uses, workflows that eliminate manual overhead, integrations that connect the dots between your stack — Performance engineering — not just PageSpeed scores, but the database queries, caching strategy, and infrastructure decisions that make a platform resilient at scale — Technical leadership: stepping in as a de facto CTO or architect, leading dev teams, reviewing code, and keeping complex projects on track — AI-powered features where they add real leverage — not as a buzzword, but built into the product where it genuinely matters My stack: PHP, JavaScript, React, Node.js, NestJS, and the full WooCommerce/WordPress ecosystem — plus whatever the problem actually calls for. I work with a small number of clients at a time. If you're building something that needs to last and you want a technical partner who's done this before at scale — let's talk.
