What I'm looking for

I’m open to full-stack development and DevOps roles, remote-first, mainly in the EU, but open to working with teams anywhere.

At Data4Life, I’m building VISIAN Image Annotator, a platform for clinical studies where teams view, label, and manage DICOM images. I developed major parts of its React and TypeScript front end and set up Playwright end-to-end tests.

Through my own work, I build and ship web apps and run production infrastructure, including a Kubernetes cluster on real hardware with more than 10 live services. I’ve also built Yogisnack, my own SaaS for independent yoga teachers, which is live in production.

At SoftIron, I built the React management dashboard shipped with the company’s clustered storage servers, along with internal tools and a cross-platform app for manufacturing workflows. I’m open to full-stack development and DevOps roles, preferably remote-first and mainly in the EU.
