While at ÅF, in 2014 Ludvig began work on the groundbreaking real time interactive application of the East Link, Sweden's first high speed railway. As of 2023, the application is still being maintained and used by Trafikverket, the Swedish transport administration. The project will start construction in 2024 and open for trains in 2035.

While working at WSP, Ludvig And Samuel created the ADTLink plugin, which connects the Unreal editor with Azure Digital Twins. The project was done in collaboration with Epic and Microsoft, and was funded through an Epic Megagrant. The plugin was downloaded over 25,000 times from the Unreal Marketplace between November 2021 and May 2022.
