About Oleksii Horban

I have been building, scaling and stabilizing Magento storefronts since 2009, starting in Magento Inc.’s original Expert Consulting Group, where I led an 11-engineer team on the Easton-Bell Sports deployment and a 4-engineer team on Longines for the Swatch Group.

Since then I have been a Principal Adobe Commerce Engineer at Guidance for eight years, working on 8-figure-GMV stores such as The Great Courses, and, since 2020, the fractional solution architect for Teabloom. Since 2024 I have led a three-engineer team at MarketNation. In parallel I have completed more than 60 engagements on Upwork with a 100 % job success score and Top-Rated Plus status.

What I am good at

• Translating business goals into technical roadmaps that non-technical leadership can act on
• Owning architecture decisions end-to-end across PHP, GraphQL, headless storefronts and cloud infrastructure
• Performance work that shows up in revenue, not only in Lighthouse
• Integrations: ERP (NetSuite, SAP), payments (Stripe, Braintree, Authorize.Net, Amazon Pay), subscriptions (Zuora, Stripe Billing), fulfillment and accounting

How I work

My engineering workflow runs through AI-augmented agents: Claude Code and Codex with custom skills, hooks and MCP integrations. It makes audits faster and code review more consistent, and it is something I help client teams adopt.

Credentials

• Adobe Commerce Architect Master certification
• 2012 Magento Imagine Challenge winner
• Upwork Top-Rated Plus, 16,000+ hours, 100 % job success

I live in Valencia, Spain, and work in English. I also serve clients in the Spanish and German markets.
