Our Tech Stack

Product Owner

Our greatest asset is people. Our Product Owners sit down with the client, listen, ask the right questions and translate business requirements into concrete product decisions. Before a single line of code is written, it is clear which problem we are solving for whom.

Miro

We gather ideas and requirements together in Miro. Customer-journey mapping, architecture sketches, story maps — distributed teams and clients work on the same board without insights disappearing when whiteboards are wiped.

Figma

As soon as the direction is set, we move quickly into Figma. Prototypes, clickable flows and visual designs are created early — so clients and stakeholders can experience ideas rather than just imagining them.

Kotlin

Kotlin is our language for backend development. Our roots are in the Java world — everything stays on the JVM, but with modern syntax, null-safety and far less boilerplate.

Arrow

We are moving from OOP towards functional programming. Arrow is the library for typed functional programming in Kotlin — it makes our domain logic more expressive and more resilient to errors.

TypeScript

In the frontend we bring designs to life with JavaScript — TypeScript only. Static types give us confidence when refactoring and make our code readable across the whole team.

Rust

Where quality and safety matter most, we write services in Rust. Errors surface at compile time — and once a service is running, it runs reliably.

Vue.js

For our frontend applications we rely on Vue 3. Why not React or Angular? Because it gets us to results quickly and produces clean, maintainable code.

Nuxt

On top of Vue we use Nuxt — the framework that gives us server-side rendering, sensible defaults and a productive developer experience, cleanly structured, SEO-friendly and fast.

AWS & Google Cloud

We run the majority of our infrastructure as Kubernetes clusters in the Amazon Cloud (set up via kops). Plan-B and failover tests run in parallel on Google Cloud — we know how to orchestrate workloads across hyperscalers robustly and cost-consciously.

Cloud (EU)

Data protection and EU sovereignty are central for many of our clients. We can also operate your workloads with European providers whose data centres are exclusively within the EU — GDPR-compliant, no third-country transfer and with clear legal frameworks.

On-Premise

We can also handle bare metal. For many companies it remains important to keep their data and servers in-house — we help operate on-premise infrastructure securely, maintainably and scalably.

Kubernetes

Kubernetes is the heart of our infrastructure. Our workloads scale automatically with load, self-healing catches failures — and our teams can focus on the application rather than the operations layer.

containerd

Our Kubernetes clusters run on containerd as the container runtime. Lean, stable and an established industry standard — exactly what we want from the layer directly beneath our services.

GitLab

Our code lives under Git version control in GitLab. CI/CD pipelines build, test and deploy our software multiple times a day — pipeline-as-code and continuous deployment are everyday practice for us, not special cases.

ArgoCD

GitOps deployments with ArgoCD: cluster state is declared and synchronised from Git. Rollouts are traceable, rollbacks are a single click, and the source of truth lives where it belongs — in the repository.

Artifactory

Release builds, Docker images and third-party libraries are all stored centrally in JFrog Artifactory. This keeps our deployments reproducible — and every dependency under control.

DataDog

Monitoring, tracing and performance analysis all converge in DataDog. Logs, metrics and traces from every service land in one place — so we find problems before our clients notice them.

MongoDB

MongoDB databases are at the heart of our applications. A document-oriented NoSQL database fits many of our domains better than a classic relational schema — and scales with them.

Redis

We accelerate our web applications with Redis as an in-memory cache. Hot data responds in milliseconds rather than being read from the database every time.

RabbitMQ

Our services communicate asynchronously via RabbitMQ. The messaging broker reliably decouples our components and makes our architecture resilient to traffic spikes.
