Software developer & the person behind Hibbisoft
BUILDING SOFTWARE SINCE2006
Same person from first hello to final commit.
02 / THE PERSON BEHIND THE PRODUCT

Hello, I’m Sebastian.
Your developer.
Curiosity included.

I’ve been building software since 2006, working across frontend, backend and architecture. Since 2017, I’ve done it through my own consultancy, Hibbisoft.

I bring experience in Agile and Scrum to the way I work with customers and teams: understanding the problem, adapting as we learn and building useful software together. Ecommerce is a big part of my story, alongside SaaS products, medical training software and mobile apps.

AI-assisted development is part of my toolkit, too. I use Codex and Claude in my software development workflow.

And when the workday ends? There’s usually another software project waiting at home.
