Software by day, endurance by weekend.

I build software for a living, run my own agency clsolutions.dev on the side, and spend what's left riding, running, and racing long-course triathlon. This is a set of notes on what I build and where I train.

A few things
worth writing about.

2024 — present

clsolutions.dev

My studio. Small-team web work, done properly.

Custom Next.js builds for clients who don't want a template and don't have time for a six-month enterprise timeline. Design system, headless CMS, Supabase, deployed on Vercel. Usually live within two weeks. I handle everything — brief to code to domain.

Life outside
the screen.

Road, trail, water, snow — most weekends end up somewhere outside. Long-course triathlon is the current project, but honestly any excuse to move works. The hours away from the keyboard are what keep the ones in front of it sharp.
