01 // ABOUT

Learning by building.

I am building my path into software development through hands-on projects. My focus is not just tutorials — I want to design, build, deploy and improve applications that solve actual problems.

I work across frontend, backend, cloud/container workflows and Android development. My long-term focus is practical software: transport systems, productivity tools, business apps and useful everyday utilities.
