The Person

Beyond the research and the product work. Who I am when I am not doing either.

About

Selected work

Six things
I built alone.

Some shipped, some pre-launch. All driven by one belief: language learning should feel calm and personal, not gamified.

I

German for the Rest of Us

An AI-assisted German course for adult self-learners, replacing jargon-heavy grammar with plain English.

EdTechClaude APIInstructional design
II

Lesson Studio

A WYSIWYG editor that revises lessons on the rendered page instead of by hand-editing JSON.

Internal toolingDOM to JSON syncDX
III

YorubaFluent

A Yorùbá platform for diaspora and heritage learners, on a hand-extended custom typeface.

IV

Vocab

Spaced repetition for 1,500 German words. Progress shows through colour, never streaks or XP.

V

WortStory

German vocabulary taught through short historical fiction, on a bracket-markup parser I wrote from scratch.

VI

LinguFlow

Audio-first drills for hands-free shadowing, backed by a CEFR curriculum across 4,000 rows.

All six,
in full.

Almost anything is possible in small, compounding steps. Little things coupled together become big, in the classroom and in the codebase alike. I build the way I think: take the next small step, trust the compounding, let the big thing emerge.
