Work Experience
Full Stack Engineer
- Built Android, iOS, and Windows apps that 80 students and 20 teachers open every day. Flutter/Dart on the front, AWS (S3, DynamoDB, Cognito) on the back.
- Before each release I asked 5+ educators what was getting in the way, and fixed that.
- Looked after the AWS and Google Cloud side: logins, file storage, the databases.
- JavaScript for the in-house web tools.
English Teacher
- Wrote EIKEN-style lesson plans for Pre-K through Grade 6.
- Kids told me which screens were confusing. I added, changed, or cut them.
STEM Educator
- Taught STEM in English to 10 students, ages 7–8, with hands-on projects and games.

Featured Projects
Audio Tools
Takes a song apart into stems and writes the guitar part out as a tab PDF. Testers get a Mac or Windows installer. The site is React, TypeScript, and FastAPI, with a job queue and object storage. Demucs does the split, the mixer runs in the browser, then audio goes to tab to PDF. A tester group has been on it since the first prototype.

A workplace app: profiles, a shared calendar, photos, comments. Flutter, so it runs on more than one OS.

D&D-style game you play by typing. An AI model writes the next bit of story, DALL-E draws the room. Classes, inventory, dice.
