Our Work

At FS Investments, we have worked with Zentered since inception. During my time as the software engineering manager on our product, I found the expertise and dedication from Zentered invaluable. Not only do they provide an incredible lift with unrivaled staff augmentation, they go the extra mile in terms of creating a winning culture and enhancing already existing process. During our time working with Zentered, we saw our developers quickly grow into top talent. The business value they provide goes well beyond complex software construction. I would be excited to work with Zentered in the future.

Arthur Tolchinsky, former Software Engineering Manager at FS Investments

Zentered helped us to create the infrastructure for a very modern and advanced blockchain based supply chain tracing solution: retraced! We are very glad having selected Zentered supporting us building from scratch the project with latest tech developments in Node: Fastify, AJV, Hyperledger Fabric, react-admin, react-native to name but a few. Not only did they help us to create it, but also consult us in respect of performance and usability for the future. Everything was delivered on time and the provided solutions were written very well. A big thank to the whole team!

Peter Merkert, CTO at Retraced GmbH

The team at Zentered helped us migrate our website from WordPress to a modern static site composed of Hugo, Netlify, and Forestry CMS. Within a few weeks Zentered re-built us a secure, reliable, and super fast website that is easy for any non technical expert to manage. Thank you for making the transition so easy!

What We Do


Our team has accummulated decades of experience with JavaScript and Node.js since 2011.

Our backend solutions are deployed in financial, social and eCommerce settings. They perform and scale transparent to the end user.

We take great care of the developer experience to build a solid base for mobile and web applications.


Be it web or mobile, a car, the fridge or a virtual voice assistant. It's how that matters most.

We work with amazing designers or take ready-made designs and build well crafted applications.

We love simplicity and never make anything more complicated than it has to be.


We chose JavaScript for a number of reasons, most important being, JavaScript is the language that powers the web. Any and every connected device can be controlled one way or another with JavaScript from websites to drones, from financial trading systems to automated car insurance systems.

Our experience and passion in Node.js has made us very confident with it.


We believe the best part of JavaScript and Node.js is the community behind it. Since 2013 we're involved in community work. We started BarcelonaJS, the Node.js User Group Barcelona, NodeConf Barcelona, MediterraneaJS and CyprusJS. Wherever we might be, we help organise NodeSchool events, give talks and support other local communities.
