Building secure, elegant software since 2017. I care about clean code, thoughtful UX, and getting data security right - on Android, on the web, and close to the metal.
About
Curiosity-driven, self-taught.
I'm a student in Germany and a largely self-taught developer. What started as a curiosity at age 12 has grown into nearly a decade of building - from tiny experiments to full applications.
My main project, KeyGo, is an Android password manager written in Kotlin - though I care less about the screens than the security systems underneath, like its AES encryption. The platform changes, that pull beneath the interface does not - my GitHub holds tools and libraries across several languages.
I'm also drawn to machine learning - close to the metal, not just calling APIs. I've experimented with image enhancement models (sharpening, deblurring) and wrote a small neural-network framework in Rust from scratch.
I learn best by making things and taking them apart.

Journey
A decade of building things.
Not a CV - a story of growth, one project at a time.
2017 • age 12
The first program
A LAN chat application written in Batch. Rough, but it worked - and it was enough to get hooked on making software.
2018 - 2020
Learning Java, properly
Rewrote the chat program in Java and started building Minecraft plugins - the fastest way I found to deepen real programming skills.
Since 2020
Apps & data security
Moved on to full applications and built KeyGo, an Android password manager with AES encryption - learning security by building it, and still shipping updates today.
2024
Abitur completed
Graduated from Julius-Ambrosius-Hülsse Gymnasium with a strong Abitur - advanced courses in Math & Chemistry.
Now
University & experiments
Studying while maintaining open-source projects and digging into machine learning - image-enhancement models and a tiny neural-network framework in Rust.
