Outside of code

Powerlifting. Five times a week, and I don't skip.
Two cats. One all black, one black and white.
Games. Grew up on my dad's PS2. Mostly CS and Valorant now.
The setup. A Windows PC for games, a MacBook for everything else, and an iPhone. Most of what I build runs on all three.
Design. Logos, game textures and UI, in Figma, Illustrator and Paint.NET.
Energy drinks. Two shelves of Monster, C4 and Rockstar cans in my room.

More about me

Writing

DLSS is brilliant. That is why it became the perfect crutch (28 Aug 2026): DLSS, FSR and frame generation are excellent tools. The problem starts when studios count them inside ordinary performance targets while conventional optimization is still arriving after launch.
I built a CMS for agents, and then had one write this (25 Jul 2026): myna.sh — why every CMS assumes a human with a mouse, and what changes when you stop assuming that.
GitHub is becoming too important to fail (21 May 2026): GitHub was supposed to be where we hosted code. Somehow it became where we host developer identity, infrastructure, and increasingly questionable ideas.
Why file transfer still sucks (and what it takes to fix it) (04 May 2026): handitoff.io — building something simple that has to deal with messy networks.
Making livery uploads less painful (01 May 2026): ERLCX CLI — turning a repetitive livery upload workflow into a simple command.
I archived my Roblox UI framework (22 Apr 2026): Rex — building a reactive Roblox UI framework, then deciding it should not be used.
When your app disagrees with itself (22 Mar 2026): ERLCX — a small incident that exposed a bigger architectural problem.
Building a marketplace with real users (18 Mar 2026): ERLCX — building and running a real platform, not just shipping features.
