What I build
I work across backend systems, infrastructure, and product engineering. I’m happiest taking an ambiguous idea, finding the smallest useful version, and carrying it from architecture to production.

How I work
Startup environments suit me: priorities move, constraints surface late, and the right answer changes as the product becomes clearer. I value direct communication, small iterations, and engineering decisions that leave room for what comes next.

Teams and community
Building software is only half the work. I’ve led teams, mentored engineers, maintained open-source libraries, and shared what I learn through this blog—work that has been featured in Ruby Weekly and other newsletters.
