Ievgenii Gryshkun

Magento 2 Engineer & Founder, angeo.dev — working with Magento since 2015

Background

I’m a full-stack Magento 2 engineer with over 10 years building, optimising, and migrating Magento and Adobe Commerce stores. Over that time I’ve worked across the full stack — custom module development, Hyvä Theme implementations, Adobe Commerce Cloud integrations, performance engineering, and complex third-party integrations.

I like infrastructure problems that sit below the UI layer — the things users never see directly but that determine whether systems can discover, trust, and transact with your store correctly. That’s what drew me to Magento in the first place, and it’s what eventually led me to AEO.

While auditing Magento stores for AI visibility, I kept finding the same pattern: stores with flawless Google rankings were completely absent from ChatGPT results. The problem wasn’t content or SEO — it was a specific set of technical signals that traditional optimisation never touched. robots.txt blocking AI crawlers, missing llms.txt, incomplete Product schema, no AI product feed. The same four gaps, store after store.

“A store can rank #1 on Google and be invisible in ChatGPT. They use completely different indexing systems — and almost nobody was fixing the AI side.”

That pattern became angeo.dev: an open-source module suite and audit toolchain that brings Magento stores from a default AEO score of ~25% to 87%+ — and helps stores meet the technical requirements for ChatGPT Shopping visibility.

Open-source is the natural fit for this kind of infrastructure work. The problems are shared across every Magento installation. The fixes should be too.


Why work with one person

angeo.dev is intentionally lean. Every audit, every module, every line of implementation code comes from me directly — not an account manager, not a junior developer working from a brief.

For technical ecommerce teams, this matters. You get a direct line to the person who built the tooling, understands the Magento internals, and has audited the same signals across Magento Open Source and Adobe Commerce stores of every size. There are no handoffs, no translation layers, no miscommunication between sales and delivery.

When the scope grows, I work with a trusted network of Magento specialists — but the technical ownership stays with me.

What I work on

My focus is Magento 2 and Adobe Commerce — from greenfield builds to complex migrations, performance engineering, and AI commerce readiness. Most projects fall into one of three categories:

AEO audits and implementation — full 8-signal assessment of your store’s AI visibility, followed by hands-on implementation of the complete Angeo module stack. Typical outcome: AEO score from ~25% to 87%+ within one business day.

Full-stack Magento 2 development — custom module development, Hyvä Theme implementation, Adobe Commerce Cloud setup, third-party integrations, and performance optimisation.

AEO monitoring — ongoing monthly score tracking, feed refresh on catalogue changes, llms.txt regeneration, and priority support.

Work together

If you’re running a Magento 2 or Adobe Commerce store and want to understand your AI visibility — or need full-stack development work done properly — get in touch.

I usually reply within 24 hours with three things: the likely root cause of what you’re seeing, whether it’s worth fixing given your setup, and the fastest implementation path. No sales pitch, no discovery call required to get a straight answer.
