As part of a small team, we built out the technical platform for Anotherblock. The product allows music rights holders to sell parts of their royalties to the public as NFTs. We also can deploy custom smart contracts and our front end both reads and writes to the Ethereum blockchain and related APIs.

I am the tech lead for the team maintaining and developing Google's website about Chromebooks. We use both Google tools and open-source software to develop a static, fast, responsive, and accessible website.

Google Assistant TV Promo App
I led a small team of engineers helping Google build a promotion app with Preact for Samsung Smart TVs, highlighting the usage of Google Assistant. Worked closely with the Samsung team to communicate between the TV and the web app using a custom API. This project included leading the code architecture, reviewing code, and overseeing the health of the codebase.

The multilingual app is available in 14 languages and has performance profiling to find and fix memory leaks.

Pigeon — Flutter App

I worked as part of a small team porting an existing iOS app to Flutter. The project was called Pigeon and was part of Google. I made heavy use of Google Maps, painting lines, and stations for all kinds of public transportation in New York City. I also used protocol buffers to work with live data, showing ETAs for incoming trains for any given station at any moment. Firebase was used for authentication as well as data about users. It required lots of UI engineering and state management.

The project has been shut down during COVID-19.

Lund University
Lund University is one of Sweden's largest universities. I was part of the team that in 2012 built and later helped maintain their new website on Drupal. We integrated with external university systems and also built a "site factory" where administrators could add and manage a local website for the university faculties.

Currency Converter

As part of my recent deep dive into React, I built a currency converter to help me keep track of exchange rates while I travel. (Due to not being able to use HTTPS with, automatic fetching of rates is disabled.)

Calorie Counter

Hobby project to practice full-stack JavaScript development. The back end is a REST API created with Express, using MongoDB as storage. The front end is using React. In this project, I increased my knowledge about API design, authentication and security (both on the front-end and back-end), as well as React design patterns. I implemented a filtering system on both date and time, which required quite a complex database query. The system also has three user roles, all with different permissions. (If the app is initially slow, it means the back-end booting up from sleep.)

The European Spallation Source (ESS) is one of the largest science and technology infrastructure projects that are being built today. Together with my team at Digitalist Sweden I planned, built, and delivered their new website in Drupal. My main focus was on overall architecture and front-end development as well as client relations and product deliverance.
