Raja Aman Ullah — Freelance WordPress Developer
WordPress & WooCommerce specialist with 8+ years of experience building custom plugins, eCommerce stores, and LearnDash LMS platforms for clients worldwide.
WordPress Developer with 8+ Years of Hands-On Experience
I'm Raja Aman Ullah, a freelance WordPress developer based in Pakistan, working with clients across the US, UK, Europe, and Australia. I started writing PHP in 2017 and have spent the years since specialising deeply in WordPress — not as a generalist, but as a developer who builds serious, production-grade solutions.
As a WordPress plugin developer, my focus is on the hard problems: custom WooCommerce plugin development, LearnDash LMS platforms with complex group registration and course logic, WordPress performance optimisation, and ongoing maintenance for sites that can't afford downtime. I've built 120+ plugins professionally — including extensions sold on the WooCommerce Extension Store and Envato Market with over 100,000 active installs.
On Upwork I've maintained a 5.0 rating across all contracts, earned 40K+, and worked with clients including Crewfare, WP Centric, Learningiscreated.org, and Science Safety. Every project is delivered with clean, documented code — no shortcuts, no black boxes.
I work directly with you — no outsourcing, no junior handoffs. When you hire me, I'm the developer writing your code, answering your questions, and accountable for every deliverable. That's the difference between a freelancer and an agency, and it's why clients come back.
WordPress Development Expertise
Eight years of focused WordPress development across four core specialisations
WordPress Plugin Development
I build custom WordPress plugins from scratch — following WordPress coding standards, writing update-safe code, and delivering full inline documentation. 120+ plugins built professionally for the WooCommerce Extension Store, Envato Market, and private clients. Plugins range from simple admin tools to complex multi-thousand-line extensions with REST APIs, custom post types, and React-powered settings interfaces.
WooCommerce Development & Customisation
Deep WooCommerce expertise covering custom plugin development, payment gateway integrations, marketplace extensions (WCFM, Dokan, Mirakl), product variation logic, checkout customisation, and subscription workflows. I've built eCommerce extensions with 50,000+ active installs and integrated online stores with third-party platforms including Mirakl and custom ERPs. See my WooCommerce development service.
LearnDash LMS Development
As a LearnDash developer, I specialise in building and customising LearnDash LMS platforms — group registration systems for B2B course sales, custom quiz logic, certificate generation, drip content, and full LMS-eCommerce integration. I've built and maintained LMS platforms for e-learning businesses including Science Safety and Learningiscreated.org. See my LearnDash development service.
WordPress Performance & Security
Comprehensive WordPress performance optimisation targeting Core Web Vitals — LCP under 2.5s, CLS under 0.1, and TTI under 3.8s. Work includes server-level tuning, caching strategy, image optimisation, database cleanup, CDN configuration, and code-level fixes. Security work covers hardening, malware removal, and ongoing site monitoring. Typical result: 40–60% faster load times. See my performance optimisation service.

Full Documentation
Every project is delivered with clear code documentation and handover notes. You always know what was built and how it works — even if you never work with me again.
