He received the UC Regents Scholarship, a full-tuition scholarship for University of California, Irvine. There, he majored in Biological Sciences and graduated in 2010. In his spare time, he became involved with Organic Chemistry research at the JS Nowick lab. He received a summer undergraduate research grant, and his research work was eventually published: X-ray Crystallographic Structure of an Artificial β-Sheet Dimer. Aaron graduated with a 3.8GPA.

After graduation, Aaron worked briefly as a private tutor before becoming a GMAT instructor with The Economist's GMAT Tutor. He worked here from 2011-2014. He took on many additional roles including sales, content writing, and customer support. Afterwards, from 2017-2019, Aaron worked as an English instructor, occasionally providing support for exams like the TOEIC and IELTS.

Starting around 2015, Aaron became greatly interested in OpenBSD and IRC. He began self-hosting and began offering free IRC and open internet services around 2019 for his friends. Around 2019, he and his friend Aadam tried to start an educational teaching startup. They later changed the project to IRCNow, which now provides internet services for the free and open source software community as well as the Christian community.
