Hire the Best 1ShoppingCart Developers
in Ukraine

**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.

I'm a full-stack developer building eCommerce systems - and lately, the AI that runs inside them. 8+ years of commercial development. I build and maintain online stores on Shopify, WooCommerce, Magento and OpenCart, write the backends and integrations they depend on, and increasingly build the AI pipelines that handle work no team wants to do by hand. Development: • Full-stack eCommerce builds and custom features - Shopify, WooCommerce, Magento, OpenCart, headless • Backend and API work in PHP/Laravel, Node.js/NestJS, TypeScript, Python • Frontend in Vue 3, Nuxt, modern JS • Performance work — Core Web Vitals, INP, page speed on large catalogs • Conversion-focused development: checkout flows, product pages, cart logic AI and automation, built into the same systems: • An AI content pipeline that processed 20,000–100,000 SKUs - generating product descriptions, meta tags, missing attributes, and FAQ content optimized for AI search engines (ChatGPT, Perplexity, Google AI Overviews) • A supplier feed aggregation service with a 6-stage product matching pipeline (NestJS, PostgreSQL with fuzzy matching, Redis) replacing manual catalog work • Meta Ads integrations - Commerce API product feeds and campaign data aggregation • Telegram and messaging bots with order notifications, support flows, and admin broadcast • Workflow automation in n8n and Make where a no-code tool is genuinely the right answer - and custom code where it isn't Stack: PHP/Laravel, Node.js/NestJS, TypeScript, Python, Vue 3/Nuxt, PostgreSQL, MySQL, Redis, Docker, OpenAI and Claude APIs, n8n, Make.

Hey, glad you found my profile. I'm a PHP Laravel Developer who actually enjoys other people's legacy code. Symfony, Shopware, Prestashop, Stripe, if it's messy and needs fixing, I'm your guy. 11+ years, zero AI-generated proposals. I've spent most of my career as a PHP Laravel Developer doing full-cycle work: database architecture, backend logic, API integrations, deployment, the whole thing. Clients usually bring me in as a Web Developer when a project needs both backend and frontend hands, or as a Full Stack Developer when the scope is bigger than that. Some of what I've built as a Full Stack Developer: B2B marketplaces, ERP systems for manufacturing and retail, and a CRM for an electric and gas utility company. One project I'm particularly proud of was a property management platform with tenant monitoring, access control, and reservations, where I worked as the Web Developer handling both the server side and the client interface. That one's a solid example of what Full Stack Developer work actually looks like end to end. Symfony is where most of my PHP Laravel Developer work lives these days. As a Symfony Developer, I lean on its dependency injection container, event dispatcher, and Doctrine ORM to build systems that stay maintainable years later, and I get pulled into legacy Symfony codebases a lot, cleaning them up without breaking production. When a project calls for Laravel instead, I switch gears as a PHP Laravel Developer and move faster with its ecosystem. On the CMS side, I work as a Shopware Developer building stores, plugins, and product catalogs, and as a Prestashop Developer handling everything from initial setup to custom modules. I've also done my share of work as a WordPress Developer, building and customizing sites and wiring them up to backend systems and third party APIs. Shopware, Prestashop, WordPress... whatever the platform, my goal's the same: clean code the store owner can actually maintain after I'm gone. I also work as a Python Developer here and there, mostly scripts and data processing jobs that plug into a bigger PHP setup rather than standing on their own. Alongside that I integrate payment and messaging tools like Stripe, PayPal, Twilio, and Sendgrid, and reach for Docker, RabbitMQ, and Elasticsearch when something needs to scale. So if you need a PHP Laravel Developer who can also cover Web Developer, Symfony Developer, Shopware Developer, Prestashop Developer, WordPress Developer, or Python Developer ground depending on what the job actually needs, that's me. Happy to own a project start to finish or just slot into a team that's already moving.
