Full-stack developer · Software engineer

Ideas, madereal.

I turn curiosity into web apps, tools, and little experiments. Mostly solo, sometimes together—always learning along the way.

01 / SELECTED WORK

Six stops. Many stories.

A field guide to the things I build—from developer tools to cultural heritage and everyday automation.

02 / THE TOOLKIT

The tools. The craft.

A focused core stack, backed by a wider toolkit. Levels are self-assessed and reflect how comfortably I work with each technology.

03 / THE JOURNEY

Built along the way.

Programming since 2019. Professional work, academic research, publication, community projects, and the lessons between them.
