I build scalable backend & mobile apps.
Hi, I'm Oskar. I specialize in building robust APIs with Go/Kotlin and high-performance native mobile experiences. Focused on architecture, performance, and clean code.
About me
I am a developer with a strong focus on backend scalability and clean architecture. I'm comfortable across the stack, but I truly enjoy building robust APIs, distributed systems, and performance-critical tooling.
Currently, I am a 4th-year student, specializing in computer systems and network administration. I'm INF.02 certified with a 100% score, demonstrating a deep understanding of infrastructure fundamentals.
I value code quality, automated testing, and pragmatic delivery. My toolkit includes Go, Kotlin, Rust, and TypeScript, and I'm always looking to master new technologies that solve real-world problems efficiently.

Selected Work
A showcase of technical challenges I've tackled.
LibrePass
A secure, open-source password management solution. End-to-end encryption ensures privacy while a Kotlin/Spring backend handles multi-device sync.
High-Performance TCP
A low-latency multi-threaded TCP server implementation in Rust. Features custom binary protocol and efficient memory management using Arc/Mutex.
Let's build something together
I'm currently looking for internships and junior developer opportunities. If you have a challenge, I'd love to hear about it.
