I design and build digital products that help people solve real problems with technology they can actually use. I conceived, researched and built ASVABIFY end to end. You talk to the person who builds it.

Why it exists

ASVABIFY started from a simple question: why does ASVAB prep still feel like a wall of disconnected facts, when the test itself is a system with explicit rules that can be taught directly?

I wanted people to study the traps in the test, not just the syllabus.

01

The challenge

The ASVAB measures which mistakes you make: every question brings wrong options that match predictable errors. The course had to teach those traps.

02

What I researched

How the AFQT score is calculated from the official table, and how adults learn when they study on their own, to order the lessons and the practice.

03

What I built

Narrated whiteboard lessons, practice tests and audio; accounts and payments with Stripe on the web and the App Store on iPhone.
