I build complex WordPress and WooCommerce platforms that go far beyond basic theme setup. My focus is custom WordPress development, WooCommerce architecture, custom plugins, API integrations, Stripe payments, ERP integrations, booking systems, e-learning platforms, AI-powered features, and internal workflow automation. I can help you with: • Custom WooCommerce stores and large product catalogs • WooCommerce checkout, payment, delivery, and order logic • Stripe, Apple Pay, Google Pay, and custom payment flows • Custom WordPress plugin development • ACF-based WordPress architecture • REST API integrations with third-party services • ERP, delivery, marketplace, and CRM integrations • Custom admin panels and internal workflow automation • Booking systems, user dashboards, and client portals • E-learning platforms and subscription-based platforms • AI-powered search, translation, and automation features • REST APIs for mobile apps and external websites • Performance optimization and production fixes Recent WordPress projects I worked on include: • A WooCommerce store with 5,000+ SKUs, payment integrations, delivery APIs, ERP sync, B2B automation, marketplace synchronization, and AI-powered product search • A custom WordPress learning platform with user accounts, lesson scheduling, Stripe subscriptions, custom admin tools, AI translations, text-to-speech, pronunciation scoring, video lesson integrations, and mobile API • A custom booking platform with Stripe payments, flight tracking, holiday-based pricing logic, user dashboard, admin management tools, and external API for connecting other websites My core stack includes WordPress, WooCommerce, PHP, ACF, JavaScript, REST API, Stripe, PostgreSQL, MySQL, React, Next.js, Node.js, Cloudflare, Vercel, and Linux-based deployment environments. What makes me different is that I do not just install themes and plugins. I build custom business logic, integrations, admin workflows, and production-ready systems that are stable, maintainable, and designed for real operations. I can take ownership of the full development process: planning, architecture, backend logic, frontend implementation, API integrations, testing, deployment, and post-launch fixes. If you need a WordPress/WooCommerce developer who can handle complex functionality, custom integrations, and production-level development, I can help you build it properly.

Payment bugs and failed webhooks cost you real revenue. I build and fix payment flows that reconcile to the cent: Stripe integrations, subscriptions and billing, invoicing, card processing, bank APIs. 10+ years of backend engineering (Node.js, TypeScript, PostgreSQL), currently a team lead at a fintech company processing millions of transactions. $100K+ earned on Upwork, 100% Job Success, including two 6-year contracts with the same clients Senior full-stack engineer with $100K+ earned on Upwork, 4,300+ hours, and a 100% Job Success Score. I ship and stabilize production web systems—from urgent Vue/Nuxt/React frontend work to Node.js APIs, PostgreSQL, payment flows, and AI integrations. I’m a strong fit when you need: • a production bug fixed without destabilizing an existing codebase • a responsive landing page or frontend implemented from Figma • a Node.js/TypeScript API or third-party integration • payment, transaction, invoicing, or fintech business logic • an n8n or OpenAI/Claude workflow engineered with retries, validation, and safe failure handling My Upwork history includes long-running full-stack products, complex frontend animation, and quick delivery on focused frontend tasks. Clients have specifically highlighted speed, reliability, and the ability to get difficult UI work right the first time. Core stack: Node.js, TypeScript, JavaScript, PostgreSQL, Vue.js, Nuxt, React, NestJS, REST APIs, Docker, payment integrations, n8n, and OpenAI/Claude APIs. Send me the current codebase, design, or production issue, and I’ll give you a direct assessment of the solution, risks, and realistic delivery time.
