Jayce graduated Illinois Valley Community college with honors and dual degrees in 2017. He continued his education at Northern Illinois University, earning his Bachelor's of Science degree in Electrical Engineering, graduating Cum Laude in 2020.

Jayce began working for Raytheon Technologies (RTX) immediately after graduation, first in Portsmouth, RI then transferring to Tucson AZ in 2022. Jayce loved spending time with his family, his friends, and his cat Nyx. He loved a good battle of wits as well as gaming & board game nights that would extend until the wee hours of the morning. He took up indoor rock climbing and hiking in AZ, and recently obtained his motorcycle license, buying his first motorcycle earlier this year. Jayce had aspirations of getting his pilot's license. Jayce will be remembered for his tenacious work ethic, genuineness, brilliant mind, disarming wit and empathetic heart. Jayce gave the best hugs!
