As CTO at Cryptar I am responsible for the design and implementation of the Cryptar notarization protocol, the setup of the frontend and backend infrastructure, the design of the microservice architecture used at Cryptar. Cryptar challenges the blockchain paradigm and combines today’s best practices in a patent pending protocol, focusing on decentralized evidence rather than decentralized operations.

As the founder of BitFlow Advisory, my role involves designing and developing the framework used to execute technical due diligence. This framework is designed to evaluate the four fundamental pillars of any IT company: the team, the process, the tools and technology, and the code and architecture. We delve into these areas to identify potential issues and provide detailed feedback on how to mitigate these concerns. We offer recommendations on choosing the appropriate technology stack and assist in sourcing employees for vacant positions. As the founder, I am responsible for presenting all information in a manner that is comprehensible to non-technical individuals, ensuring they understand the implications of our findings.

As the Head of Blockchain Development, I was accountable for the conception, design, and implementation of the notarization protocol of all issued TrueProofs, which are documents summarizing the validated user data. This notarization was carried out using a smart contract on the Ethereum blockchain. Following this, I was responsible to oversee the development of the TrueProfile.io product suite, encompassed the technical design of the software and the coordination of development with a team of more than 30 developers implementing the feature designed by the product team.

As CTO at Bernstein, I was responsible for the design of the API and the service-oriented architecture, the infrastructure setup, team management, and the recruitment of new employees. The main application is fully containerized and divided into production and staging environments for seamless and automated testing and releases. The frontend implements an encryption layer using WebCrypto API where all user input is only stored fully encrypted in transit and on rest (end-to-end encryption). The Bitcoin blockchain is used as settlement-layer for the designed notarization protocol.

As Interim CTO at Planerio, I was involved in the design and implementation of the time tracking service and provided consultation for the shift-optimization algorithm. I also contributed to the design and conceptualization of the backend.

As Lead Software Engineer for Backend I was conceptualizing and designing the Foodora Backend, which was utilized by over 2000 restaurants. The restaurants used this backend to input their details, manage their opening hours, handle orders, and manage payouts. Additionally, I developed a machine learning algorithm that predicted future orders based on historical data, which assisted in optimally positioning the riders while they awaited new orders.
