Pavlo S.

I've built and maintained WooCommerce stores doing $2M+/month and helped build a platform that grew from $0 to $80M a year. I'm a WordPress and WooCommerce developer and technical architect, and I fix the setups that hold growing stores back. Growth is usually a technical problem in disguise. Most of my clients don't need a freelancer to knock out a task. They need someone who can see the whole system and own the result. What I work on: — Custom WooCommerce development: checkout, subscriptions, pricing logic, and custom plugins, including the things off-the-shelf plugins can't do. — Speed optimization and performance: caching, database queries, and server tuning that keep a store fast on its busiest day. — Scaling beyond WordPress: moving heavy logic like inventory, pricing, and order processing into dedicated Node.js/NestJS services, so WooCommerce stays the storefront. — Fixes and rescues: downtime, hacks, malware, and sites that fall over under traffic. — Tracking: GTM, GA4, Meta, and Triple Whale, set up so the numbers are right. — Technical leadership: acting as a de facto CTO by leading dev teams, reviewing code, and owning architecture. Results: — A profitable store kept going down and getting hacked. I cleaned up the server, closed the security holes, and got Core Web Vitals into the green. Once the site was stable, marketing could finally work, and revenue grew 60% that year. — A high-risk US merchant needed features WooCommerce didn't have. I built a multi-step checkout, upsells and bundles, custom inventory and forecasting, a custom ERP, and high-risk payment gateways with failed-order recovery. They became the largest store in their niche. — A venture-backed company's site crashed at about 100 concurrent users. The problem wasn't traffic but missing caching and a misconfigured server. I rebuilt it to hold up under real load. Stack: PHP, JavaScript, React, Next.js, Node.js, NestJS, and the full WordPress/WooCommerce ecosystem. For larger builds, I work with a small team of engineers I've partnered with since 2015, and I take on a few clients at a time. If your store is slow, breaking, or outgrowing WordPress, or you want a technical partner who owns the outcome, let's talk.
