Toolchain and build tools at Ubisoft. LLVM Release Manager.
2025 is shaping up to be one of the weirdest years I have ever had. Right now I just want to fast forward my life until 2026.

I worked quite a bit on the toolchain stuff for this, hitting a consistent 30FPS was a hugely collaborative endeavour between toolchain, rendering and other engine work. It's the first time we ship a game with CSPGO as well, which helped in dense areas. Hope you enjoy!

Went to the co-working office today and made a decent effort to find a fit. This shirt is pure autumn vibes.

@rebeccafernandez.bsky.social if this is not RIGHT up your alley I don't know how badly I have read your taste in music :-)

Let me know if it's annoying with my music recs, but I don't have that many people that seem to have a similar taste in female fronted metal :)

Running "git repack -adf --path-walk" in my local llvm-project shrunk the .git folder from 3GB to 1.7GB. Very helpful!

@rebeccafernandez.bsky.social This might be something you'll like - maybe a bit to far on the hardcore side, but there is something about the dynamics in this track that I love: www.youtube.com/watch?v=QTA6...

Just discovered Landmvrks and this recording of Creature at Hellfest. Relentless and the singer Flo does an amazing job. Rapping, growling and belting. Top tier stuff: youtu.be/MmRoDovSZ1o?...

After 2 months of work, the Clair Obscur Expedition 33 video is here. I interviewed most of the game's senior leadership team asking one simple question: how did you do this? Their answers were inspiring and moving, and it's no surprise that COE33 is as remarkable as it is: youtu.be/mXLOLgC2V2Q?...

It’s really cool to see my talk freely available for everyone. I’m proud of the work our team accomplished, and it means a lot that it’s now accessible to a wider audience.
Huge thanks to the GDC team for putting it out there!

After an intense week of meetings and conference in Montreal I am home and have a week of. I will relax by ... remodelling our kitchen.

At least I will have a bit of time to play FF7 Rebirth as well!

Back home after a week in Montreal. It was great fun to hang out with my team IRL, had great food and beer and many interesting discussions. My talk got very good feedback as well.

With all that said. It's so damn nice to be back home.

Montreal has so much good food. I am constantly blown away about the quality!
