Software Engineer focused on blockchain since 2020, with lots of experience in electrical and mechanical engineering
About Me
I started with a lot of technical interest in all kinds of hardware, especially guitar tube amps. Music pulled me into electronics, then into microcontrollers and IoT, and finally into software. After my first studies in βIndustrial Engineeringβ in March 2022, I joined 42 Heilbronn (a project-based coding school) and finished the program plus an internship by December 2024. Software engineering, is not just a job for me, it is a passion. I enjoy reading and reverse-engineering code to keep learning and to find creative, fast, and elegant solutions.
Since December 2024, I have been working as a βSoftware Engineer & Head of ITβ at Arkadia Heilbronn gGmbH. Arkadia reimagines the education system with a focus on software engineering. I build and maintain our websites and internal tools. I designed and now maintain the on-site IT for the company and our coding school students, from networking and device management to CI/CD and observability. I like pragmatic, MVP-first iterations and refactoring toward good and clean code incorporating user feedback, with a focus on full-stack engineering.
I am especially interested in Ethereum and privacy-preserving identity. Participating in Ethereum hackathons is one of my favorite things to do, prototyping ideas, learning from the community, and staying close to the ecosystem. When I am not coding or thinking about code, which is rare, you will find me tinkering with hardware, cars, or music gear.
Hackathons
Love to attend hackathons and build things with other people. Finished as a finalist/1st place 6 times. Which resulted in over 48k$ in prizes.

Crypto/Blockchain
Built an end-to-end encrypted, fully anonymous, censorship-resistant messenger that stores messages in Ethereum blob storage, ensuring invisibility, unlinkability, and complete decentralization. Developed a single frontend compatible with both browser-based wallet interactions and World Mini Apps, removing the need for separate codebases and deployments.

Crypto/Blockchain
Developed a system that securely creates a verified association between passport data and a wallet. This is done by reading the passport data through NFC (ICAO Doc 9303) and validating it inside a TEE, which then submits it on-chain.

Singapore, Singapore
Crypto/Blockchain
Developed a service which abstracts the need to manually transfer gas to each chain, this is done automatically by the service.
-ETHGlobal Istanbul
Istanbul, Turkey
Crypto/Blockchain
Developed a fully functioning browser-based wallet that completely abstracts the different chains, making it easy for the user to use.

Sustainability
Built a mobile app similar to a Tamagotchi, which you can feed with the products you consume. Based on their impact on the environment, it becomes healthy or unhealthy.
