Breno Gonzaga

Founder, Affex

I founded Affex after years of using spaced repetition tools (Anki, Noji, and others) in real study contexts, from language learning to professional certification exams. My background combines hands-on SRS practice with educational technology and software design, and it's what shapes every article and every product decision here.

Areas of Expertise

Spaced Repetition Science

Deep knowledge of the SM-2 algorithm, Ebbinghaus Forgetting Curve, and cognitive load theory.

Educational Technology

Experience with Anki, Mnemosyne, SuperMemo, and modern learning apps across iOS and Android.

Cognitive Psychology

Applied research on active recall, interleaving, elaboration, and retrieval practice.

Language Learning

Practical experience using SRS for Japanese, Spanish, French, and Portuguese vocabulary acquisition.

Course & Curriculum Design

Structuring units, lessons, and exercises into skill trees that teach a subject progressively, the same format that makes Duolingo-style courses work.

Editorial Standards

Every article on the Affex blog is grounded in peer-reviewed research. I cite primary sources — not secondary summaries — and link directly to studies in journals such as Psychological Science, Journal of Experimental Psychology, and Psychological Bulletin.

Techniques recommended here are ones I've personally tested in real study contexts. I don't publish speculative claims about memory or learning without scientific backing.
