Work

Systems that run. Not just concepts.

Selected platforms, products and open-source infrastructure – with traceable architecture, technical decisions and real results.

From cloud foundation to consumer app

Featured case

Reproducible Kubernetes data platform

A complete platform for local development and AWS – from networking and Kubernetes to the data pipeline and GitOps handover.

Starting point

Cloud and data platforms are often assembled from manual steps, disconnected tools and undocumented decisions. Rebuilding them becomes a risk.

Our solution

The cloud foundation and cluster are created from code. From Flux onwards, GitOps owns the desired platform state. The same functional components can be reproduced locally on Kind and in AWS.

Selected work

Products and infrastructure built in-house.

Every case combines product decisions, architecture and operations – not as an isolated demo, but as a system with a concrete use.
