Alaster Alfio

Software Developer

Dip. Digital Design & Development, Republic Polytechnic · Graduating Sep 2026

Spent the first half of 2026 building path-safety tooling at LTA. Now shipping small tools while I wait on graduation.

Progress

Ship30

A public commitment to ship 30 small, finished things. The bar for each one is that it gets released and solves a real annoyance.

Each drop gets its own repo and shows up here as an achievement. The count is public so that stalling is obvious.

1 shipped. 29 to go.
