If your app is broken, behind schedule, or stuck with bugs you can’t diagnose, I can help. I’m a senior full-stack developer with 30+ years of experience fixing, stabilizing, and finishing production systems—especially React, Node.js, APIs, and databases. I’m often brought in when: • A project is partially built but stuck • A previous developer disappeared • Bugs are blocking launch • APIs or integrations aren’t working My focus is fast diagnosis, clear communication, and shipping fixes—not rewrites. I’m a hands-on developer with 35 years of experience delivering production software across web, backend, and infrastructure systems. In recent work, I’ve been building and fixing applications using React, Node.js, MongoDB, and modern cloud environments. I also work with Web3 systems when needed, including Ethereum and Solana smart contracts, token integrations, and wallet-based workflows. With experience across many languages and platforms, I adapt quickly to the problem at hand and focus on getting things working reliably. Common fixes I handle: • API integrations that fail, timeout, or return incorrect data • Third-party API auth, webhooks, and data sync issues • React rendering, state, and performance issues • Node.js / Express backend errors and crashes • MongoDB schema, query, and data issues • Finishing half-built MVPs I’m available for short-term fixes or ongoing support.

SHOPIFY & WOOCOMMERCE ARCHITECT | CUSTOM LIQUID & PHP ENGINEERING Most e-commerce stores operate at a fraction of their potential because they are weighed down by "app bloat" and conflicting plugins. Whether you are on Shopify or WooCommerce, relying on high-fee third-party apps that don't communicate leads to slow load times, security vulnerabilities, and lost profit. I bridge this gap by combining Custom Liquid Development and WooCommerce PHP Engineering to turn standard storefronts into high-performance, automated revenue engines. I don’t just "install themes." I build the features and backend logic that power them. From architecting private Shopify Apps to developing custom WooCommerce hooks and functions, I weave your store into production-ready workflows using tools like n8n, Make, and Shopify Flow. Whether you need a headless commerce solution, a specialized subscription portal, or a complex multi-vendor integration, I build the technical infrastructure that lets you scale your GMV without adding operational headcount. CUSTOM THEMES & HEADLESS DEVELOPMENT I provide end-to-end development for Shopify Plus and WooCommerce. This isn’t just a "skin"; it’s a mobile-first, high-performance storefront built for your specific brand logic. Shopify: 2.0 Theme migrations, custom Section blocks, and Headless Commerce using Hydrogen/Oxygen. WooCommerce: Custom child themes, specialized product builders, and REST API integrations to keep your site lean and lightning-fast. I specialize in bypassing heavy builders like Elementor or Divi to create clean, coded layouts that rank better on Google. E-COMMERCE AUTOMATION & BACKEND ARCHITECTURE I build advanced logic to handle tasks that standard settings cannot. This includes custom API integrations between your store and your ERP/CRM, complex JSON data parsing for inventory, and automated database management using Airtable or SQL. If you need to sync high-volume data with external warehouses or reduce Zapier costs through self-hosted n8n, I architect the entire pipeline. API INTEGRATIONS & THIRD-PARTY SYNCING I specialize in creating seamless connections between your store and the tools that run your business. Whether it’s connecting Shopify to a custom fulfillment center or syncing WooCommerce with specialized accounting software, I handle the heavy lifting of API documentation and data mapping. I ensure that your customer data, inventory levels, and order statuses are updated in real-time across all platforms, eliminating manual entry and reducing the risk of overselling or data silos. SUSTAINABLE GROWTH & SCALABILITY Building a store is one thing; building a store that can handle a 500% spike in traffic during a Black Friday sale or a viral TikTok launch is another. I audit your server environment (for WooCommerce) and liquid logic (for Shopify) to ensure your architecture is "stress-test" ready. By optimizing database queries and utilizing edge delivery networks, I ensure that your site remains stable and fast regardless of volume, providing a consistent experience for every customer. SPEED & CONVERSION OPTIMIZATION (CRO) I transform slow, low-converting sites into high-velocity machines. By fixing Core Web Vitals, optimizing image delivery, and minifying scripts, I ensure sub-2-second load times. From Shopify Checkout Extensibility to custom WooCommerce checkout flows and one-page checkouts, I eliminate friction to drive higher AOV and conversion rates. My goal is to move you away from expensive monthly subscriptions into a clean, optimized, and owned technical environment. AI-DRIVEN PERSONALIZATION & INNOVATION I integrate AI models (GPT-4, Gemini) for more than just chatbots. I build agents for personalized product recommendations, automated sentiment analysis of customer reviews, and photorealistic AI-generated lifestyle content for your galleries. Using tools like HeyGen and Midjourney, I can even automate your video ad production, ensuring your shop is populated with high-quality content that understands your customer’s intent. TECHNICAL STACK Development: Liquid, PHP, JavaScript, HTML/CSS, React, Node.js, GraphQL, Ruby on Rails, GitHub. Platforms: Shopify (Plus), WooCommerce, WordPress, Hydrogen, Oxygen, BigCommerce. Automation: Shopify Flow, n8n, Make (Integromat), Zapier, WP All Import, Klaviyo, MailerLite. AI & Data: OpenAI (GPT-4), Google Gemini, Airtable, SQL, Google Merchant Center, Midjourney. KEYWORDS FOR SEARCH OPTIMIZATION: Shopify Developer, WooCommerce Expert, Custom Liquid Theme, WordPress Developer, PHP Engineer, Store Speed Optimization, Shopify Private App, Headless Commerce, n8n Integration, Conversion Rate Optimization, CRO, Shopify API Developer, WooCommerce Hooks, Subscription Development, Product Configurator, Custom Checkout, Data Migration, AI Personalization, App Bloat Removal, Shopify Plus Consultant, WP Engine, Full-Stack E-commerce, Inventory Sync, ERP Integration.

I help businesses turn AI ideas into working systems that support real operations - not just polished demos. I start with a quick discovery call to make sure we are aligned and to confirm the right scope before any work begins. That usually makes the process smoother for both sides. What I build • AI agents and LLM integrations using OpenAI, Claude, LangChain, and RAG pipelines • Workflow automation with n8n, Zapier, Makecom, and custom API bridges • Internal tools and no-code/low-code solutions that reduce manual work • Secure architectures for teams that need reliability in regulated or compliance-sensitive environments What I’ve Delivered • Reduced manual operational workload by 40–70% through AI automation • Built AI workflows processing 10,000+ tasks and requests per month • Cut response and processing times from hours to minutes using automated pipelines • Integrated AI systems with CRMs, internal dashboards, Slack, and third-party APIs • Delivered MVPs and internal AI tools in as little as 2–6 weeks • Helped teams scale workflows without expanding operational headcount How I Work • Async-friendly and easy to work with • Clear scoping before any code is written • I document what I build, so you own it after delivery • I flag scope creep early, not after billing it If you need someone who can connect AI, automation, and internal tools into one practical system, I can help from strategy and architecture through implementation.
