Hire the Best OsCommerce Developers in Kharkiv, UA

**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.
