I have been fascinated by software development since the age of fifteen. As an autodidact I taught myself the necessary skills to create Filewidget, a light&fast widget, which can create shortcuts to any file or folder and instantly reached 100,000 installs, and very good reviews.After apprenticeships with Austrian software companies I became a freelance developer, developing web applications and mobile apps for companies and games and media apps offered for iOS and Google App Store. As my projects grew in scope, I founded Linkplicity Ltd, developing blockchain-based systems for businesses to certify quality and reward recycling. As my own projects, I implemented the music life streaming service Webstagemusic and the CRYPTO Shih Tzu NFT project. Currently, I am working on a digital platform for the Jam Music Lab private university in Vienna, covering music life streaming and music NFTs.I have experience in NextJS, React, NodeJS Express, Ionic, React Native and Solidity and love to develop software.End of 2022 I received US patent "Blockchain-based system and method for peer-to-peer online advertising auction". The invention describes a smart contract and a secure multiparty computation protocol for a uniform price auction of ad impressions where consumers receive cryptocurrency for watching ads. I have started to develop a business model on this basis.
