Vacuumlabs

I helped building one of the first decentralized exchanges on top of Cardano blockchain. My responsibility was the architecture of the off-chain components of the smart contracts, and providing domain knowledge to help make technological and business decisions.

Vacuumlabs

Rychlotest Covid, covid testing with good UX, was the first product I worked on. I helped modernize the UI, and I introduced granular permission system to the application. The second project was Cardano application for the Ledger hardware wallet, written in embedded C. This project helped me understand blockchains in general and the ins and outs of Cardano.

Microsoft

I participated in a learning program for high school students called "Študentské trénerské centrum", where I improved my presentation and soft skills. After graduating I got promoted to the Learn Student Ambassador program. As part of the program I led several webinars for teachers in Slovakia about Azure and security.

Revolware

I worked mainly on Laravel backends for client and in-house applications. I also started the company's Linux server used for self-hosted web, mail, file storage, and private Git hosting for projects, with CI/CD baked in.
