I build the web at Night Network; from a browser inside a browser to open-source tools, used by 500k+ people a day.
Cambridge, MA
I'm Leo (online, Crllect), a developer in Cambridge, MA, focused on building products people actually use. I'm co-owner and a developer at Night Network, a privacy- and access-focused web organization that partners with TitaniumNetwork and serves hundreds of thousands of users a day at peak. Right now I'm also interning at Audible through their Future Leaders program.
Most of my work blends careful frontend craft with the backend and infrastructure to run it at scale. I care a lot about UI/UX, performance, and shipping things that feel finished. My day-to-day stack is Astro, TypeScript, Tailwind, and Bun, and I lean into React/Preact when a project needs it.
Outside of Night Network I build open-source tools, do some security research with my school district's IT team, and have done a couple of hackathons.
A few of the products I've shipped — most are live and in daily use.
