In addition to providing music-tech and leadership consultancy services, I led the development of a welfare technology system for digital home visits in elder care through a small in-house team. Driving the product's journey from concept to product launch, we collaborated directly with users and built on existing standards and tools. This approach allowed us to deliver a cost-effective, competitive solution that quickly reached profitability.

As a Developer at Utopia, working with data processing in Go, I adapted DNA sequencing algorithms for music playlist processing and optimized core algorithms for performance. I took end-to-end responsibility for data quality within our data platform, ensuring both accuracy and reliability throughout. Beyond my technical contributions, I played an active role in shaping our engineering culture.

As a consultant, I continued working with some of Sweden's largest hauliers and WAPPO AB, expanding the logistics platform with fleet management and user-friendly back-office capabilities. I had sole responsibility for the back-office system and its required APIs in the logistics platform which meant that I worked across the entire stack with Vue.js in the frontend and Laravel in the backend.During this time I also had various shorter assignments supporting teams with the development and maintenance of go (golang) and Java systems.

In this role, I started focusing more on backend development as I created several real-time integrations which later came to be the foundation for the company's core business. Much of the work I did in this period was focused on a logistics system for one of Sweden's largest hauliers built in PHP on top of Laravel. Due to performance requirements, I also worked extensively with performance optimization in MariaDB (MySQL).

Worked as an all-round web developer creating both small marketing sites with plain Javascript, HTML, and CSS as well as larger customer sites and internal systems built on top of WordPress or Laravel. Due to the small size of the company I mostly structured my own work, collaborating with customers and design agencies as needed.
