Aladtec & InstaSub.
Improved a scheduling platform trusted by public-safety teams and redesigned a mobile substitute-teacher app.
The problem
Aladtec served high-stakes public-safety scheduling, but its UX hadn't kept up. InstaSub's mobile flow lost users at the moments that mattered most.
The thinking
"Treat scheduling as a trust product. Every confirmation, swap, and notification has to feel calm and unambiguous — even at 3 a.m."
Process
Four moments that shaped the work.
Listening to the operator
Shadowed dispatchers and substitutes to find the moments where the UI broke their rhythm.
Targeted UX improvements
Redesigned shift swaps, approvals, and notification flows. Cut friction without breaking habits.
InstaSub mobile redesign
Rebuilt the substitute-teacher app around speed, glanceability, and one-handed use.
New web modules
Designed and shipped new modules into the existing system without fragmenting the experience.
