About me

Linux developer focused on building scalable backend systems and clean, maintainable architectures.

I enjoy working close to the system — containerization, automation, APIs, and infrastructure — while still crafting efficient and structured frontend interfaces.

I value simplicity, performance, and understanding how things actually work under the hood.
