THE FOUNDATION
01 / UNDER THE HOOD
APIs, integrations and the logic behind the experience. Built to handle real business, from a first release to a busy campaign.
THE FRONT WINDOW
02 / MADE FOR THE WEB
From the first product idea to the details users interact with every day. Interfaces that bring your product to life.
THE COMMERCE COLLECTION
03 / ADD TO POSSIBILITY
Connect the storefront, search, customer engagement and payments. Make the moving parts work together.
One developer. Mix-and-match expertise. Checkout starts a conversation.
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.
20 projects. From 2006 to today.

build.
