to make
any of this.

Federico Cossia · Argentina

I'm Fede. I build apps around things I'm curious about. I also work on other people's products.

In the works

Independent projects

Dogtor

IN PROGRESS

A tool for veterinary appointments and communication. A little less back-and-forth around the everyday work of caring for animals.

NookTok

RESEARCH IN PROGRESS

I'm exploring a library for the books you actually own: their covers, re-readings, and the sessions between one page and the next.

Tiny Color Lab

IN BETA

A drawing and coloring app for kids, with simple tools and room to make something of their own.

My clock,
from the inside.

My commit history, by hour. The closest thing I have to a self-portrait.

Commits by hour 2023–2026

7,403 commits, 761 days, three and a half years. 39% of them between midnight and six. Best hour: 01:00, 782 commits. Worst: 08:00, just 25.

My record is 85 commits in one day. I was also still committing at 08:00 that day — one of just 8 times that’s happened in three and a half years.

Counted October 2, 2026.

This chart is my clock.

Work for others

Someone else's logo.
My three in the morning.

I also build products with someone else's logo on them. Interfaces, flows, and integrations. Each team's details stay with that team.

Off the clock

Not everything ends up in git.

Coffee, the games I play, and the music I listen to are part of the self-portrait, too.
