[SINCE] 2018
An e-commerce software house —
operators, [
not an agency]
We ship Medusa.js and Next.js, but first we ran e-commerce from the inside — in stores doing €25M+ a year. The code you get understands not just Core Web Vitals, but product margin.

I
Four things we'll say out loud.
Most software houses build stores. We've run them — every day, for years. That's how we know what actually makes money in e-commerce, and what's just a nice slide.
[ 01 ]
Code that reads the P&L.
Every technical decision has a margin cost. The architecture we ship is optimized for cost-per-order, not just Core Web Vitals.
[ 02 ]
We have skin in the game.
We work as e-commerce management for brands doing €25M a year. The store we build for you is the kind of store we spend our Monday mornings in.
[ 03 ]
Launch is not the finish line.
Most builds die six months after go-live. We stay longer — as your fractional tech + ops team — until the store grows into the scale we promised.
[ 04 ]
We say no to agency stuff.
We don't promise 200% growth in three months. We don't sell brand strategy decks. We don't take builds we don't believe in. Everything other shops won't say out loud.

What we actually do.
End-to-end: from audit, through headless commerce build, to running ops. Take the full stack or just the pieces.
→ /01[svc.01]
Medusa.js
Composable commerce on an open backend. Data modeling, custom modules, integrations, performance tuning.
→ /02[svc.02]Next.js
Stores built on App Router, server actions, ISR. Lighthouse 95+, edge-ready, ready for scale.
→ /03[svc.03]E-commerce ops
Interim / fractional Head of E-commerce. We join your Slack and own the KPIs — not the slide deck.
→ /04[svc.04]Sales Manago
Official partner. Implementations, custom workflows, RFM segmentation, scenarios that actually convert.
→ /05[svc.05]Performance audit
Frontend, backend, infra, unit economics. You leave with a concrete list — 7 / 30 / 90 days.
→ /06[svc.06]ERP · PIM · OMS
Subiekt, Comarch, MS Dynamics, Akeneo, custom PIMs. We wire systems so ops can stop living in Excel.
→ /07[svc.07]Migrations →
Shopify Plus → Medusa, Magento → headless, WooCommerce → Next. No SEO loss, no downtime.
→ /08[svc.08]Composable commerce
Best-of-breed architecture. Vendor orchestration so SaaS bills don't eat your EBITDA.
→ /09[svc.09]Tech advisory
Board- and CTO-level advisory. Build-vs-buy, pre-investment due diligence, technical roadmap.

No fluff.
Four steps. Each one with ownership on our side.
/ 1–2 wks
i.
Business audit
We start with the P&L, not Figma. Your numbers, cost-per-order, product margin, funnel.
/ 2 wks
ii.
Architecture
What stays, what we replace, what we build from scratch. Roadmap with budget and dates.
/ 8–16 wks
iii.
Build
Discovery sprint → MVP → iteration. Code review, tests, monitoring from day one.
/ ongoing
iv.
Operate
We stay. Fractional tech team + e-commerce management — until you hit promised scale.
VI
Let's talk real numbers.
The best projects start with a short call about your actual P&L. No NDA, no 80-question brief.
