Find your starting point

What are you trying to solve?

You do not need to choose a service first. Bring us the problem.
Our experts will identify the cause, set the priorities and define the right path forward.

These are common challenges we help clients understand, prioritize and solve.

Pages take too long to load, errors keep appearing or releases create new problems. We find what is causing the issues and improve the performance and stability of your platform.

Your current setup worked in the past, but it has become difficult to maintain, scale or change. We help you modernize, rebuild or move to a platform that better supports where your business is going.

Know what to fix first

Start with a clear view of your platform

You know your store needs attention, but you are not sure what is causing the problem or what to fix first.

A Kiwee Audit gives you an independent view of your platform, the risks behind the issues and a prioritized plan for what to improve next.

What makes Kiwee different?

Software that fits how your business really works

The most expensive code is the code you have to write twice or more. On complex projects, the real cost is rarely the building. It is building the wrong thing. Or hitting a serious problem halfway through, when fixing it is slow and expensive.

So we think before we build.

A woman with a black turtleneck and black pants points to a detailed workflow diagram on a glass whiteboard, explaining steps like Concept, Prototype, and User Test to a man in a green sweater and black pants. To the left are many multi-colored sticky notes. They are in a modern, industrial-style office with concrete floors.

We map how your business works, how customers move through your store, and where the risks are. This happens on a whiteboard, not in a live system. It is cheap, and it is where costly surprises get caught early.

A problem found in planning costs a conversation. The same problem found after launch costs weeks of rework and lost sales. We find the hard questions early, while they are still cheap to answer.

Most delays come from the unexpected appearing mid-project. We work backwards. By the time we commit to a date, we have already found the things that usually break dates.

Since 2019 we have run Shopware and Magento on portable, cloud-native infrastructure, no lock-in, your data under your control. We were solving this before it had a name, and the work is public and still maintained.

THE CHALLENGE

The store was slow, interactions felt unresponsive and it was failing Google's Core Web Vitals.

WHAT WE DID

We reviewed the platform, found the biggest performance problems and created a prioritized improvement plan. We then worked with the client to implement the most important changes.

THE RESULT

  • 50% faster page loads
  • 56% faster interactions
  • Core Web Vitals from failing to passing in 3 months

THE CHALLENGE

NFC21's Shopware 6 store had outgrown its technical setup. Deployments carried unnecessary risk, the CMS was too rigid for the marketing team, and no one knew where the biggest conversion and performance gaps were.

WHAT WE DID

We introduced a CI/CD pipeline for safe, automated deployments, replaced the legacy CMS with a headless architecture on Strapi and 11ty, and ran UX, SEO, performance, and green website audits to find the real problems.

THE RESULT

  • 4+ years of partnership
  • Zero release anxiety
  • Countless bottlenecks removed

What our clients say about us

  • Thanks to Kiwee, we improved our Git and Continuous Delivery workflow and focused on achieving new goals. Kiwee delivered the project on time, conducted one-on-one sessions, and discussed challenges in an agile manner. The communication and quality feedback were commendable. What I find unique about Kiwee is their honest feedback and direct developer-to-developer communication, where the whole team strives for solid and sustainable technical solutions.

Data protection & compliance

Compliance, engineered from the start

Data protection is not just a legal box to tick. It shapes your infrastructure, integrations, access and where data sits, affecting your GDPR position, and accessibility now does the same across the EU.

We do the engineering, your legal team the policy, and we build compliance in from day one.

You work with a dedicated Kiwee team based in Europe. The people with access to your systems and data are named, accountable and reachable. Nothing is handed to an unknown subcontractor.

We build on portable, cloud-native infrastructure with no lock-in to a single provider. You decide where your platform and customer data are hosted, including on European soil, and you can move them whenever you need to.

Since June 2025, the EAA has made accessibility a legal requirement for many online stores. We audit your store against it, fix what falls short, and build new features to meet it from the start. Compliance becomes part of the platform, not a scramble before a deadline.

From 18 February 2027 the EU requires a Battery Passport, the first of its Digital Product Passports, with textiles, electronics and furniture to follow. It is a QR-linked, structured product-data record, which is an engineering and integration problem. We build the data infrastructure it needs, once, so you are ready as the rules reach your category.

The people behind Kiwee

Senior leadership behind every engagement

Kiwee is not built around anonymous delivery teams or layers of handover. Our projects are led by experienced people who understand software engineering, architecture, delivery and the business impact of complex eCommerce platforms.

When you work with Kiwee, you work with a senior engineering partner that stays close to the decisions shaping your platform.

Tomasz Gajewski

CTO

Tomasz has 22 years of software engineering, built at companies including Microsoft and Idealo, one of Europe's largest eCommerce platforms. He owns Kiwee's technical direction and guides the architecture, infrastructure and platform decisions your long-term growth depends on. If you have a hard technical call to make, this is who you make it with.

Frequently Asked Questions

Common questions about working with us

Yes. Many clients come to us with a problem, not a ready technical brief.

Tell us what you are seeing, whether that is slow performance, lost sales, checkout issues, difficult updates or growing operational effort. We will assess the platform, identify the underlying causes and explain them clearly. This may be a short consultation, an audit or a defined development task.

Yes. We start with a technical review, so the handover is controlled and realistic.

We check the codebase, infrastructure, documentation, current risks and open issues. After that, we prepare a clear takeover plan, including what needs to be fixed first and what can wait.

Yes, and protecting those three is the point of how we plan a migration.

We map your data, your URLs and your integrations before anything moves, so products, customer history and search rankings carry over intact.
Cutover is planned to keep the store trading and the timeline predictable. Replatforming to Shopware and Magento is work we do often, and we would rather move you carefully than fast. You get a clear plan for exactly how your store gets from where it is to where it needs to be.

Yes, and it is one of the most common ways clients work with us.

We work alongside your team rather than taking over, giving you senior architecture, Shopware and Magento, or cloud and DevOps skills when you need them, without the cost and lead time of permanent hires. Your team keeps ownership. We fit into your tools, standards and release process.

Yes, and it is one of our strongest areas.

We connect stores with ERP, PIM, CRM, CMS, payment, shipping and warehouse systems, so data flows reliably and manual work and errors drop out of product updates, orders, inventory and customer data. After many years of this, we know where integrations break, including with legacy systems, and how to build them to keep working.

You can leave cleanly, and we plan for that from the start. Everything we build is yours, documented and handed over so another team can pick it up without us. No proprietary lock-in, no code only we understand, no accounts you cannot access. In practice, clients stay because they want to, and many have for years.

Security is built into how we work, not added at the end. We follow secure development practices, control who has access to what, and keep dependencies patched and monitored, which is visible in the way we maintain our open source projects. Sensitive data is handled with privacy and access in mind from the architecture stage.

You do. All of it: the code, the infrastructure, the hosting accounts and the data. We build on portable, open foundations, so nothing is tied to us or to a single provider. You are never renting access to your own platform. If you ever want to bring the work in-house or hand it to another team, everything is yours to take.
