Off the Clock

Beyond the Code

🏎
Formula 1

Avid F1 fan — race weekends are sacred. There's something about the intersection of engineering precision, strategy, and raw speed that never gets old.

🎮
Sim Racing

Active sim racer on iRacing. The feedback loop of analyzing your own data to shave tenths off a lap time scratches the same itch as debugging a performance problem.

🌿
Plants

Growing collection of houseplants. There's a patience to it — you can't force a plant to grow faster, you just set up the right conditions and trust the process.
