Measured PIV field, −10° to +25°. In-between frames blended, airfoil outline fitted
UCF EAS3810C · Fall 2026

PIV on a single airfoil

Measured the flow around an airfoil in a water tank with particle image velocimetry at eight angles of attack, then turned the vector fields into circulation, lift, and Reynolds number.

What I did
  • Processed all eight angles in PIVlab and found why the exported images held almost no particles, then picked ensemble correlation and a three-pass window schedule that worked anyway.
  • Wrote a MATLAB batch script on PIVlab's own functions, checked it against the GUI result at 0° (all 377 valid vectors match), and used it for the remaining angles.
ResultLift coefficient follows the reference chart's trend from −5° to +5°; a MATLAB pipeline that reproduces the PIVlab GUI vector for vector

Experience

I have a strong bias for hands-on engineering where the data proves the design. The Starship program taught me that humility is part of the engineering. Look past your own assumptions and lean on the technicians who run the hardware every day. Care about getting it right for the vehicle, not just your own design. Everything I build runs through the same four steps: design, build, test, and scale.

~10xproduction-rate scale-up my bonding cell was designed for, adopted at CDR
~90%cost cut from a DOE I ran
80%+less marking time per part with my laser cell
12projects owned or led, concept to hand-off

I worked on the team responsible for Starship's thermal protection hardware at Cape Canaveral. My days were split between development work and the production floor. Development meant research, design, planning, and building out project proposals. On the floor, I worked with technicians to integrate equipment and run down root causes when something failed. Much of the job was taking requirements that were undefined or still moving and turning them into proposals, engineering models, drawings, and hardware. Then I validated how they actually held up during integration and testing.

Two areas took most of my time. The first was inspection and test. I developed clearer ways to verify heatshield components at every stage, from the first step through integration on the vehicle. That included physical testing on T1 flight hardware. The second was equipment engineering, where I ran trade studies, specified cells, and stayed with them through procurement, installation, and the first weeks on the floor. I also replaced a manned, semi-automatic ink station with an automated laser marking cell that cut marking time per part by more than 80%. I designed it in NX, assembled it alongside technicians, and it ran with near-continuous uptime. My largest project was an automated bonding cell for Starship V3, designed from the start around the rate the program needs. In July, the thermal protection system had flight-blocking needs in Texas. It's still the most critical system on the vehicle, so I surged from the Cape to the Starfactory at Starbase to help on site.

I split my time close to evenly between the desk and the floor. I mentored technicians and other interns on the work I owned. I learned that a big part of being an efficient engineer is teaching others how they can help instead of doing everything yourself. Late in my term I presented my work to Starship program leadership. My review package became a reference for the rest of the team.

Operating at the speed of a flight program was my biggest learning curve. Early on, some of my work was set aside as requirements shifted. That taught me not to take pivots personally and to refocus where the team needed me. Later I was trusted with sole ownership of several systems that are still operational today. I learned that acting quickly and with intent, then learning from the result, beats waiting for the perfect decision.

360%projected fuel grain capacity gain from my tooling
50,000+ lbfhorizontal static fire stand
3,500 lbfN2O/ABS hybrid campaign, parachute bays fired
U.S. Armyprograms carried through hot fire and delivery

I was a propulsion design engineering intern at a hybrid rocket startup in Addison, Texas. My days were split between the desk and the floor. At the desk I designed in Creo Parametric 9, ran structural analysis, and developed tooling. The rest was hands-on work on the floor.

My main project was FDM tooling for fuel grain production: one-time-use molds with O-ring glands and vacuum-capable iterations. Testing validated seal integrity, bond-layer uniformity, and cure. The projected result was a 360% gain in production capacity. I also spent real time in the lab formulating adhesives and iterating fuel grain geometry. That work fed straight back into the same bottleneck my tooling was built to fix.

I kept up with my project well enough to go looking for more. I helped build out a water flow test stand. I also designed a 50,000+ lbf horizontal static fire stand, from CAD through the plumbing and assembly. On a 3,500 lbf N2O/ABS hybrid campaign, I designed, built, and fired parachute bay assemblies. The successful hot fire was presented to the U.S. Army. They used a shear-screw breakaway and a black powder charge of my own design. I owned their test plans in Epsilon3. I also worked with the company machine shop to CNC and lathe parts on the critical path for flight tests, including igniters and test fixtures for U.S. Army programs that went on to a successful hot fire and delivery.

What I walked away with came from the tests that didn't go the way we expected. There was a lot of failure. Many times, something I thought I understood got challenged. It taught me to work backwards from a result to find where and how something failed. That prepared me for what came next more than any result that went right.

How Firehawk changed how I work
Failure is the dataMost of what I learned came from tests that didn't go as expected. I work backwards from the result to where it broke.
Own the testI designed, built, and fired my parachute bay assemblies, owned their test plans in Epsilon3, and the successful hot fire was presented to the U.S. Army.
Fix the bottleneckMy grain tooling, adhesive work, and geometry changes all went after the same production limit.
Then ask for moreOnce my project was on track, I went looking for more. I helped build a water flow test stand and designed a 50,000+ lbf static fire stand.

4 wk → 6 hsame-batch processing
100sruns tracked

I'd call this my first real engineering job. SRT made regolith simulant for aerospace customers, and the process ran almost entirely on tribal knowledge.

I spent my days watching where waste was produced and working out how to fix it. Then I worked entire shifts on the line myself with the operators to make sure each fix actually held. Before changing anything, I tracked units per day, batch time, labor, faults, and downtime across hundreds of runs.

Then I reorganized the production cells around Lean Six Sigma, integrated the equipment, and wrote the SOPs. Same-batch processing went from four weeks to six hours. The lead manufacturing engineer adopted the flow.

1stinternship, senior year of high school
Scan vs CADredesigned parts checked against ATOS blue-light scans in GOM Inspect
H₂gas-turbine fuel research presented to the engineering team

My first internship, at a company that reverse engineers and manufactures replacement parts for industrial gas turbines.

Most of my time went into learning Siemens NX and redesigning several turbine fixtures and parts. Then I blue-light scanned the real parts on an ATOS ScanBox and compared them to my models in GOM Inspect. That comparison is where tolerances, manufacturing defects, and what machining actually does to a design first made sense to me.

I worked through my assignments quickly enough to ask for more. So I researched hydrogen as a fuel for gas turbines: what it takes to produce, store, and use it responsibly. I presented what I found to the engineering team. It was the first time I saw how engineering actually gets done. It's a large part of why I chose aerospace.

I'm an aerospace engineering student at the University of Central Florida, finishing my degree in December 2027. In Florida, launches have always been part of the view. Chasing that feeling pulled me into a cockpit first, and then onto test stands and factory floors.
