**OpenCart is complex. Finding someone who truly knows it - even harder.**
After 10+ years and 170+ completed projects, I specialize in one thing: making OpenCart stores work the way your business needs them to.
I'm not a generalist. I live in OpenCart's codebase - from legacy 1.5.x to the latest 4.x architecture - and I know exactly where things break and why.
**What I do:**
- **Custom Modules** -Features OpenCart doesn't have out-of-the-box, built clean and maintainable
- **API Integrations** - Payment gateways, shipping carriers, CRM/ERP, logistics services
- **Performance & SEO** - Slow stores lose customers; I fix the root cause, not the symptoms
- **Deep Debugging** - Complex PHP/MySQL issues other developers avoid or misdiagnose
- **AI Workflow Automation** - Replacing repetitive manual tasks (content generation, data enrichment, catalog management) with Claude/OpenAI-powered pipelines
**My stack:** PHP, MySQL, JavaScript/jQuery, REST APIs, Git · **AI:** Claude API, OpenAI API, Claude Code
**What sets me apart:**
- 100% Job Success Score across 170+ projects
- I've handled integrations most developers won't touch - custom logistics APIs, multi-warehouse sync, high-load catalog optimization
- I use AI tools daily in development - faster delivery, fewer bugs, better code
- You get working code, clear communication, and zero hand-holding required on your end
**If your OpenCart store has a problem, I've probably solved it before.**
Send me a message with what you're dealing with - I'll tell you honestly if and how I can help.

Slow Magento store, a failed Shopify migration, a broken WooCommerce checkout, or a store that gets traffic but does not sell? That is exactly what I fix. And if you want to add AI to your store, I can tell you where it actually helps before you spend a penny on it.
I help online stores fix, optimize, migrate, and scale Magento 2, Adobe Commerce, Shopify, Shopify Plus, WooCommerce, and WordPress, with a focus on speed, Core Web Vitals, conversion rate optimization (CRO), technical SEO, custom development, and long-term growth.
I am the founder and CEO of MageCloud, an eCommerce development agency with 17+ years of experience in Magento development, Shopify development, WooCommerce development, eCommerce CRO, performance optimization, and custom integrations.
On Upwork, I have earned $2M+, completed 275+ jobs, maintained 100% Job Success, and achieved Top Rated Plus. Clients hire me when they need a senior eCommerce developer who understands both the technical side and the business impact behind it.
MAGENTO DEVELOPMENT
• Magento 2 and Adobe Commerce development, upgrades, and support
• Custom Magento modules, checkout fixes, and Hyvä theme development
• Magento speed optimization, Core Web Vitals, Varnish, indexers, and cron
• Magento 1 to Magento 2 migration, Magento to Shopify migration, and replatforming
• Magento ERP, CRM, and PIM integration via REST, GraphQL, and queues
SHOPIFY DEVELOPMENT
• Shopify and Shopify Plus development and theme customization
• Custom Shopify apps, private apps, Shopify API integration, and automations
• Shopify speed optimization, Liquid performance, and Core Web Vitals
• Shopify migration, Magento to Shopify migration, and platform migration planning
• Shopify ERP, CRM, payment, and shipping integrations
WOOCOMMERCE & WORDPRESS DEVELOPMENT
• WooCommerce and WordPress development and custom plugin development
• WooCommerce speed optimization, caching, database tuning, and Core Web Vitals
• WordPress plugin cleanup, security hardening, and malware removal
• WooCommerce migration from Shopify, Magento, and other platforms
• WooCommerce ERP, CRM, and third-party API integrations
AI FOR ECOMMERCE
• AI development and AI integration for Magento, Shopify, and WooCommerce stores
• AI chatbots, AI-powered search, product recommendations, and workflow automation
• LLM integration (OpenAI / ChatGPT, Claude) and generative AI for product content
CRO, SEO & GROWTH
• Conversion rate optimization (CRO) for Magento, Shopify, and WooCommerce stores
• GA4 analytics, funnel analysis, heatmaps, A/B testing, and UX
• Checkout, product page, and cart optimization
• Technical SEO, Core Web Vitals, and performance optimization
• eCommerce audit, Magento audit, Shopify audit, WooCommerce audit, and roadmap
• Rescue projects after failed development, broken checkout, or tech debt
My work is not limited to writing code. I look at the full eCommerce picture: how your store performs, where users drop off, what creates friction at checkout, how product pages convert, where AI can remove manual work or lift conversion, and which decisions help you scale without adding technical debt.
Many clients come to me with problems like:
• "Our Magento 2 store is too slow."
• "Our Shopify store gets traffic but does not convert."
• "Our WooCommerce checkout is broken or losing revenue."
• "We want to add AI but do not know where to start."
• "Our current developer disappeared or left technical debt."
• "We need a senior Magento, Shopify, or WooCommerce developer who can own the project."
That is exactly where I can help. As an eCommerce consultant and founder of MageCloud, I can work as an individual senior specialist or bring in a team of developers, designers, QA specialists, and project managers when needed.
I like to start with a roadmap, not jump straight into development. First, I figure out what actually matters: what needs fixing first, what will boost conversion rate, what lowers risk, and what gives the store the best ROI.
Why clients work with me:
• $2M+ earned on Upwork, 275+ jobs, 100% Job Success, Top Rated Plus
• 17+ years in Magento, Shopify, and WooCommerce development
• Magento 2, Adobe Commerce, Shopify Plus, WooCommerce, and Hyvä experience
• Strong focus on CRO, technical SEO, speed optimization, and long-term support
• AI integration for eCommerce, applied where it genuinely adds value
• Complex stores, custom integrations, AI features, rescue projects, and migrations
If your Magento, Shopify, WooCommerce, or Adobe Commerce store has technical issues, low conversion, slow performance, unstable integrations, a risky migration, or a failed development project, send me a short description of your store, current problem, and business goal. I'll help you define the best next step: an eCommerce audit, a rescue project, a Magento, Shopify, or WooCommerce migration, speed optimization, CRO, or a custom integration.

I’m a Business Development Manager specialising in Shopify development, full website migration projects and performance-driven design, working closely with a dedicated in-house delivery team as part of the Cart Blender agency.
My role is simple: understand your business goals, translate them into a clear technical scope, and connect you with the right solution. I act as the bridge between business needs and the in-house technical team, making sure expectations, timelines, and budgets are aligned from day one.
What we help with:
– 1) Full Shopify & Shopify Plus migrations (from WooCommerce, Magento, PrestaShop, etc.)
– 2) Theme customisation & custom Shopify development
– 3) Performance-oriented UX/UI designs
– 4) Complex eCommerce data migrations
– 5) SEO-safe migrations (301s, structure preservation, performance)
– 6) Ongoing support, optimisation, and technical consulting
At Cart Blender, we’ve delivered and supported 400+ Shopify projects since 2018 for SMB brands, often acting as a long-term technical partner rather than a one-off vendor.
I don’t push unnecessary features or inflate scope – I focus on defining what actually delivers value and ensuring the project starts on solid ground.
You’ll get:
- Clear project discovery and scoping
- Realistic timelines and reasonable budgets
- Direct access to an experienced Shopify team
- Transparent communication throughout the process
If you’re looking for someone who can think strategically, communicate clearly, and take ownership of results, I’d be glad to help.
