Most agencies sell you the illusion of the “golden conversion lever”.

The truth is: there is no magic. There is only diagnosis, mathematics and clean craftsmanship.

You're probably here because you know your shop could make more revenue. Maybe you're wary of “optimizations” that end up just costing money, or you're frustrated with agencies where the boss does the pitch but a junior practices on your revenue.

I work differently. We don't guess. We diagnose. Instead of blindly testing ideas, I use the MECLABS heuristic to pinpoint exactly where Friction or Anxiety keeps your customers from buying. We don't force success through luck — we stack validated wins on top of each other.

Four Levers. One System.

No more “gut feeling”

We don't start with guesses. We start with data.

I screen your shop for technical brakes and psychological hurdles (Friction & Anxiety). Instead of blindly testing ideas, we build a roadmap based on hard facts that shows you which levers promise the biggest revenue jump.

Proof, not promises.

Every one of these shops didn't just hit our 10% guarantee — they blew past it. That's what happens when you replace gut feeling with data.

From niche experiment to profitable business case

Conversion Rate

We scaled the complex re-commerce model from low 4-figure to stable 6-figure monthly revenue. Through continuous testing we quadrupled the conversion rate (+300%) and made the project profitable.

AOV Increase

Scaled from 5-figure to 7-figure annual revenue. Over our long-term partnership we didn't just massively increase the conversion rate — we lifted the average order value (AOV) by over 150%.

Conversion Uplift

Speed is money. We rebuilt the entire shop in just 4 weeks (clean code). The result: an immediate 20% increase in conversion rate right after go-live, driven by better UX and lightning-fast load times.

What started as a small experiment is now a load-bearing revenue pillar. The technical execution and strategic guidance were the key to this massive growth.

Our profitability has completely turned around. Not only do we convert more visitors — they also spend more than twice as much as before.

Finally a shop that runs technically clean. The relaunch was stress-free and the numbers went up immediately. That's exactly how tech should work.

Everything that moves your revenue.

CRO Audit & Diagnosis

I screen your shop for psychological hurdles and technical brakes. We find out exactly where you're losing revenue.

App Development

I build custom functionality as clean code. That lowers your monthly fixed costs and keeps the shop fast.

Modular Theme

We build a “Lego system” (modular sections) that lets your marketing team assemble landing pages in minutes — no developer needed.

High-Performance Speed

I guarantee a Google Speed Score of 90+ (mobile). The result: better rankings, cheaper clicks (CPC) and fewer abandoned checkouts.

Shopify Migration

We migrate products, customers and SEO rankings safely to Shopify. No data loss, no downtime.

A/B Testing

We test variants against each other and scale only the winners. That's how we harness the “compound-interest effect” for maximum revenue growth.

Hydrogen Storefront

We build ultra-fast custom storefronts on Hydrogen for maximum performance and total design freedom.

Headless eCommerce

We decouple frontend and backend (e.g. React/Next.js) to enable complex user journeys and international setups.

Tracking & Integrations

We connect ERP, CRM and tracking tools seamlessly. So you can trust your numbers and make data-driven decisions.

No vendor platitudes. Real feedback.

I'm not looking for clients for one-off gigs — I'm looking for partners for long-term growth.

Founders and managers on how working together has affected their business — honest, direct and unfiltered.

Wen Hao
Wen HaoCo-Founder, MaoMao
If you're looking for a developer who blindly executes orders, you're in the wrong place. Stawros challenges ideas constructively and understands the big picture behind the code. He doesn't just deliver technical execution — he brings strategic proposals that have massively improved our user experience and our processes. A true partner over many years.
Jens Oellrich
Jens OellrichTeamlead RE-USE, Bergzeit
There were no off-the-shelf solutions for our complex re-use model. No matter how specific our requirements were, Stawros always found a way to implement them cleanly. He works extremely fast and precisely, and played a major part in us reaching our goals.
Markus Foelsch
Markus FoelschMarketing Decision-Maker & B2B Sales
I can recommend working with him without reservation. Stawros doesn't just work fast — he always has the right plan ready when something gets stuck. For us he's like a Swiss Army knife of e-commerce: extremely competent, absolutely reliable, and with the right solution for every technical problem.

Find out where you're losing revenue right now.

I personally analyze your Shopify store for technical brakes and psychological hurdles. In a call together I'll show you exactly which levers we need to pull first. Free & no strings attached.

  • Personal analysis, no automated reports
  • Concrete levers instead of a sales pitch
  • 100% value, in under 30 minutes

100% value. No aggressive sales pitch.

No results, no costs.

Cost Reduction

I replace expensive subscription apps with clean code. The monthly savings often directly fund part of our work together.

Speed Guarantee

Your shop reaches a Google mobile score of 90+.

Owner-Led

I handle a maximum of 5 projects at a time. You always talk to me, never to a junior.

Your guarantee: no fine print, no excuses. If we miss the target, I keep working for free until we reach it.

Common questions, answered honestly.

Perfect. Treat this audit as an independent second opinion. Agencies often go blind to their own work. I uncover the blind spots others miss. And if your shop is already perfect, I'll tell you that honestly.

No. We follow the principle of “diagnosis before prescription”. On the call I'll show you concretely what's broken (Friction) and what's missing (Anxiety). Whether we work together afterwards is entirely your decision.

Not for this first audit. I analyze the user experience exactly the way your customer experiences it. I look for the hurdles that keep visitors from buying. No passwords required.
