I'm Aaron Riddle, a finance student at the University of Central Florida. I grew up in Lakeland, Florida, and earned my associate degree from Polk State College through dual enrollment while I was still in high school.

I started at UCF in mechanical engineering and switched to finance. The engineering side still shows up in my work: at Siemens Energy I do cost research and modeling for energy infrastructure projects, and on my own time I build software with AI.

Along the way I built and sold a vending machine business and co-founded a student solar racing nonprofit. Outside of work you'll find me playing pickleball, studying poker strategy, skydiving or at the piano.

I owned the cost research for a $6M substation conversion project, built a capital cost model from 25 benchmarks across five technologies (battery storage, solar, wind, gas turbines and more), and scored 100+ potential solar sites for client recommendations. I joined in March 2025 as a finance intern, linking $200M+ across 1,000+ wind project invoices into tracking files.
