Curiosity,
made useful.

I build software for the real world. Physics, geometry, and architecture shape the way I think about it.

Selected work About me Open web sandbox

A study in tension, gravity, and connection.

PRACTICAL SOFTWARE. PERSONAL CURIOSITY.

Selected work.

Two hands-on studies in building software you can reason about. Change a condition. Inspect the consequence. Keep the evidence.

DISTRIBUTED SYSTEMS · FAILURE REHEARSAL

System Wind Tunnel

A lost reply shouldn’t create a second order.

Drop a response. Retry the request. Compare what happens with and without duplicate protection, then inspect the events that explain the difference.

Run the failure experimentBrowser simulation · Separate recorded HTTP/SQLite experiment
Request → retry → consequence

Why I’m building itWorking on software that connects payments, drivers and devices taught me to ask what happens when a message never arrives. This is a small, inspectable way to answer that question.

DATA QUALITY · EXECUTABLE EVIDENCE

Follow the Thread

Turn a questionable value into a repeatable test.

Trace an invoice total to its source. Change the rule that accepts it. Export a Python regression that reproduces the result outside the browser.

Investigate the invoiceSynthetic invoices · Executable rule checks · No live OCR
Source → rule → reproducible result

Why I’m building itI want to know why software trusts a number. The same curiosity that draws me to mechanisms becomes a practical habit: follow the evidence, and make the check repeatable.

A LITTLE ABOUT ME

I like knowing
why things work.

I’m Luis, a full-stack software engineer in Puerto Rico. My day-to-day work connects software to the world around it: drivers, payments, printers, public-health workflows, and the people who depend on them.

I’m interested in the connection between a well-built system and a physical structure: what holds it together, where it can fail, and how to make the result easier to understand. These personal projects let me explore those questions in public.

THE SIDE OF MY DESK

A binder of curiosities.

Watches with my dad. The architecture of home. A question that turned into a little instrument. Browse when you feel like wandering.
