00 The Story
2022 — Present
From grief to the grid

A driver built in a cockpit. An engineer built in the data.

Born and raised in New York City, I found racing in 2022 — a refuge from the grief of losing my father. What started as escape became obsession, then discipline, then career.

Four years later I've competed on the Road to Indy ladder with Jay Howard Driver Development, tested with ENVE Motorsports in USF Pro, and graduated the Motorsport Technical School's DAG track as a Performance Engineer. I'm now in Carmel, Indiana, living and breathing the sport from both sides of the garage wall — building the car, driving the car, reading its data, and chasing the only goal that still matters: a professional seat on the way to the NTT INDYCAR Series, and becoming the first Puerto Rican to do so.

Chapter One

Learn to drive.

Skip Barber Formula Series · Car #30

Sebring was where the helmet went on for the first time — and where I decided not to take it off. A year after losing my dad, I walked into Skip Barber with no ladder-series background and every reason to feel out of place. The paddock didn't care. The car didn't care. Every lap I got better, and every session the grief got quieter.

Skip Barber's formula curriculum taught me the fundamentals — braking cadence, rotation, reference points, racecraft — and gave me a full season of wheel-to-wheel across some of the hardest circuits in the country. By the end of it, this wasn't therapy anymore. It was a career.

Chapter Two

Road to Indy.

USF Pro Championships · #7 JHDD

Jay Howard Driver Development put me on the ladder. Road America in the rain. The IMS Combine under empty grandstands. Portland, Putnam, Mid-Ohio, NOLA — a field of drivers every bit as hungry as me. For the first time I wasn't a student, I was a racing driver with a data engineer, a setup sheet, and a qualifying session that mattered.

What I took from JHDD is something every real ladder team teaches you by force: how to communicate. How to turn a feeling in Turn 5 into a spring rate on a sheet of paper. How to sit down after the session and defend your in-car reasoning to an engineer who has three sessions of data to disagree with you. That loop — feel, data, conversation, change, lap — is the loop I still run today, just from the other side of the desk.

USF Pro Championships · IRP Oval · May 2025

In May 2025 I stayed with JHDD as spotter for the IRP Oval round — calling car position and incident data live to the driver and engineering stand. Standing above an oval rewires how you see racing: you stop watching cars and you start watching space. It's a skill I now apply to every coaching job I take and every strategy call I make from the pit box.

Test. Develop. Repeat.

ENVE Motorsports · Thermal Club

As Test Driver for ENVE Motorsports, I spent 2024 and 2025 doing the work most people don't see: multi-session days at The Thermal Club, running structured setup sweeps and delivering the kind of feedback an engineering team can actually build on. Damper changes. Ride-height deltas. Aero balance. Tire-temp windows. Session after session.

Thermal taught me precision. You don't get points for a hero lap in a test — you get points for a clean, repeatable lap that isolates one variable. In May 2025 I joined the ENVE USF Pro program as a driver coach at the IRP Oval, bringing driver insight back to the pit stand for a full race weekend. Both seats. Same car. Same sport.

04Motorsport Technical School — Race Engineer2025 — 2026
Lead Race Engineer · DAG Graduate

The other side of the wall.

I graduated the Motorsport Technical School's DAG (Data Acquisition & Analysis) track yesterday, April 18, 2026, in Carmel, Indiana — an intensive race-engineering program covering data acquisition, vehicle dynamics, tire science, aero balance, suspension, powertrain analysis and race strategy on the Ligier JSF4 platform.

I led the team as Race Engineer for our F4 track day at Putnam Park: I rebuilt and reorganized the wiring loom and harness on the Ligier JSF4, serviced all engine and chassis connectors, contributed directly to a full engine swap, and monitored HPD engine parameters during first crank. I sourced the full technical manual library (HPD, Sadev, JRi, AIM, Tilton, GEMS) and worked directly with manufacturers through my personal industry network to resolve engineering questions in real time.

I also built the team's entire engineering document stack from scratch in Excel — run plan, setup sheet, driver procedure, lap tracker, tire tracker, engine break-in tracker, spare parts manifest, and driver feedback sheet — plus a live setup configuration app at gysetupconfig.netlify.app.

05Eclipse Competition — Elite Sim RacingPRESENT
Active Engineer

Setup work for elite sim teams.

Off the physical grid, I'm a setup engineer for Eclipse Competition — an elite sim-racing team competing at the top of iRacing. My job: develop, test and validate the setups that put Eclipse drivers on the front row of the hardest online series in motorsport.

Eclipse is not a bedroom roster. The lineup is built almost entirely of real-world racers — people who know what a car is actually doing on track and can give the kind of feedback an engineer can build on. That's the reason the setup work matters here: it's the same DAQ, the same tire-model questions, the same damper-vs-spring conversations — just with a different telemetry pipe. Every hour here feeds directly into the real-world engineering I do at the track, and vice versa.

06Why I Race — ExCampsEXPERIENCE CAMPS
This is the why.

ExCamps gave me the tools to grieve when no one else was — and they do it for thousands of young people across the country.

Racing gave me somewhere to put the grief. ExCamps gave me the permission to feel it first. If any part of my story resonates with you, this is where that story actually starts.

A Cause I Stand Behind

No young person should grieve alone.

Experience Camps is a free, one-week program for kids who've lost someone close to them. After my father passed in 2022, they were the first place where I didn't have to explain what I was feeling. Racing is the result. This is the origin.

If you're a potential sponsor or partner, I donate a portion of every sponsorship contribution to ExCamps. Details on request.
