I'm Jason Alexander R. Mangahas, a developer based in Dasmariñas, Cavite, Philippines. I build web and mobile applications, provide hardware and software support, and handle esports production.
I graduated from Philippine Women's University with a BS in Information Technology, Summa Cum Laude (GWA 1.15), Class of 2026. I'm CompTIA ITF+ certified and have served as President and Vice President of PWU's Information Technology Society.
