WHAT I BRING TO A TEAM

I ship software where
failure affects real work.

I follow the work across interfaces, services, devices, and data: understanding the requirement, building the integration, testing the change, and explaining it to the people who use it.

FIELD OPERATIONS

Dispatch that keeps working between connections.

Shipped a bilingual React driver PWA on Azure with WebSocket updates, adaptive polling, and offline synchronization.

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.

PERSONAL PROJECTS · EXPLORE THE WORK

Built out of curiosity.
Open for exploration.

Working tools for the problems I keep coming back to. Try the workflow. Change a condition. Look inside the result.

RELIABILITY / DISTRIBUTED SYSTEMS

The reply disappears.
The order shouldn’t repeat.

Send a request, lose its reply, and retry. See how one design creates duplicate orders—and how a better one prevents them.

A custom 3D design model: a coral request passes through a blue gate between a sender and a durable store, with a separate retry path.
Design model · not a live simulation

One request identity. One durable result.ORIGINAL 3D STUDY

From my workbenchDrivers, payments, and devices taught me to design for the moment a connection drops. This is that question, made tangible.

DOCUMENTS / HUMAN JUDGMENT

A decision is stronger
when you can trace it.

Three documents disagree. Compare the original passages, make a considered decision, then unfold the exact evidence behind it.

From my workbenchDocument-driven work made me interested in the line between what software can establish and what still needs a person. I built that line into the interface.
