Nazar K.

I’ve been developing and customizing OpenCart stores since 2013 — 100+ projects across e-commerce, API integrations, and custom module development. My core expertise: payment & shipping modules, store migrations (2.x → 3.x), security hardening, and complex API integrations. I also develop fiscal receipt modules (CheckBox ПРРО) for Ukrainian e-commerce — automated receipt generation compliant with Ukrainian tax law. I work across OpenCart 2.x and 3.x. I take time to understand each client’s business processes in depth — not just the technical task. This means I can spot inefficiencies and suggest practical improvements to how the store operates, beyond what was originally asked. I’m always happy to jump on a Zoom or Google Meet call to discuss your project requirements in detail before we get started. If you need someone who knows OpenCart’s architecture at a deep level — not just surface customizations — let’s talk.
