Experience

Cyberhaven

https://www.cyberhaven.com/
A cybersecurity start-up where I was hired at the early stage and assisted all the way to the MVP and series B stage. I prototyped a lot of features to get feedback from customers quickly. Much of my work related to creating custom visualizations with D3.js and highly tailored forms for configuring security policies. The biggest achievement was creating a prototype of completely new visualizations of the dashboard within a limited timeline. This allowed us to win several customer demos and make our existing customers happy.

3d Printing Start-up

A 3D-printing start-up that challenged many traditional supply chain constraints and opened up new opportunities. They digitized the industrial supply chain and made it an integral part of the process.

I oversaw the front-end of the application and assisted in creating it from scratch. I also launched the app, implemented authentication, and developed a multi-tenant app to provide different views for various roles according to role restrictions. We implemented this in a way that significantly sped up the process.
