Marek Kubacak.

Fifteen years in Adobe Commerce and Magento: agency-side, merchant-side, and now independent. Adobe Certified Solution Specialist, Meet Magento and MageTitans speaker, and a stubborn believer that the platform is rarely the real problem.

I started Hashira because the merchants I kept meeting had the same story: good business, capable team, and a platform that was being blamed for problems nobody was actually diagnosing. Agencies that quoted bigger, platforms that promised more, and nobody in the room whose only job was to look out for the merchant.

So I became that person. Hashira is a consultancy, not an agency. I don't ship code, I don't resell licences, and I don't take commissions from vendors. What I do is sit on your side of the table and help you see the system you're actually running: so the decisions you make next are the right ones.

Why "Hashira"

柱: The Pillar.

Hashira (柱) is Japanese for “pillar.” In a building, pillars don't make the noise, sell the tenant, or get photographed for the brochure. They hold the thing up.

That's the job. A good consultant isn't the loudest voice in the room: they're the reason the room stays standing when the agencies, the vendors, and the boardroom are all pulling in different directions. Quiet, load-bearing, in your corner.

The name also echoes Tron. Fight for the users. In our case: fight for the merchants.

Speaking & Community

Ideas tested in public.

The thesis behind Hashira: that the platform is rarely the real problem, is something I take to the Magento community stage wherever it's invited. Beyond speaking, I also organise Meet Magento Czech Republic, returning in August 2026 after a community revival.

The Team

Hashira is a small team of senior specialists.

Marek is the advisory face. He leads client conversations, audits, and strategic decisions. The architectural and technical depth is held by a colleague certified as Adobe Commerce Architect and Adobe Commerce Developer. When we audit code or design architecture, he has the final say.

We extend the team with people we've worked with for years, scaled to what the engagement needs. The promise is the same whoever shows up: no juniors at senior rates, no headcount inflation, every person someone we'd trust to audit our own business.
