From the ground up
About Leo
Leo is a web app for managing construction and housing renovation projects that digitizes the entire project lifecycle — preparation, planning, execution, and closeout — connecting clients, contractors, and subcontractors in real time, from team management to invoicing.
My role
- Redesigned the user interface for the existing web app
- Designed Leo's native app from scratch
- Developed Leo's design system and brand language
- Interviewed users across different roles to identify pain points and translate them into interface solutions
