Assorted Projects

Previous Roles

2021–2023

Backend Developer at Mojang via Netlight

Employed as a consultant at Netlight with an assignment at Mojang.

I was part of the Java Game Services team in Mojang, that supplied the core services used by Minecraft: Java Edition. Being the world's best selling game, the services needed to be performant to handle high load, not only for legitimate traffic, but also a range of DDoS attacks. At Mojang, I helped with their Xbox integration and I helped to design and implement the secure chat reporting system, that combines cryptography and graph theory to ensure integrity of reports in Minecraft's distributed server architecture.

2020–2021

Fullstack Developer at Klarna via Netlight

Employed as a consultant at Netlight with an assignment at Klarna.

At Klarna, I was a fullstack developer at their rewards club—Vibe—where you unlocked gift cards as you purchase with Klarna. Using data-driven development, supporting over 1.5 million users with different app versions, we have delivered incremental improvements to the rewards program, Klarna and Klarnas customers.

2018–2020

Fullstack Developer at Precisit AB

From 2018–current employed at Precisit AB with different in-house projects, mostly in the role as a fullstack developer.

Teaching Assistant at Uppsala University

I have been a teaching assistant for the course Imperative and Object-Oriented Programming Methodology at Uppsala University years 2017, 2018 and 2019.

As a teaching assistant I've learned a lot about coaching and helping others to find a solution on their own. This skill is valuable in a team since it increases the team's collective knowledge of the system.

Education

2015–2020

Master's Programme in Computer and Information Engineering

Studied the Master's Programme in Computer and Information Engineering at Uppsala University, with a specialisation in software development. Grade average: 4.68 / 5.

Specialisation in software development, the focus was project methodology and processes, with the goal of answering the question of ‘what are the critical success factors for a software development project?’

My master's project investigated memory efficient conflict-free replicated data types in a peer-to-peer distributed system on the Web, which are data types that can be used to enable collaborative experiences.
