I am a software developer focused on backend and mobile projects.
I completed a Bachelor of Computer and Information Sciences in Application Development with an 89.78% average, and I am a member of the Golden Key International Honour Society.
Before software, I worked for over 5 years in finance and administration at STC International. That experience made me detail-focused and practical in how I design systems.
