Hi, I'm Arthur.
I take software from a napkin sketch to production, and I stay until it works.
Uruguayan developer, based in Asunción, Paraguay.
Why trust me with your project
I own the whole thing
At Slick+ I went from the Figma mockups to the API to the AWS CDK and CI that deploy it. No hand-offs, no "not my layer".

I fix the "won't fix" bugs
Videos recorded in Chrome couldn't be seeked and S3 wouldn't stream them. Chromium marked it won't fix; I re-encoded everything into adaptive HLS with a Lambda.
The video saga →
I make slow things fast
I compiled NIST's fingerprint C code to WebAssembly so biometric checks run in the browser: no API round trip, and it works offline.
NBIS-JS, open source →
I clean up messes
At Reps&Co I took over a ticketing system written by non-engineers and turned it into something fast that the team could actually work on.
Reps&Co →
I ship, constantly
Rooster gets a release almost every day. The green dot up top is my last push, live from GitHub. It's rarely old.

I've been the founder
I co-founded Tenacit and ran it serverless on AWS for almost nothing. I know a feature is only done when someone pays for it.
