Task management app with habit, routine, and TODO tracking.
A personal productivity app built to unify habits, routines, and TODOs in a single interface — built around the concept of "getting every day on track." Built with Vue.js and Ruby on Rails, backed by PostgreSQL.
Designing a unified interface for three different task types — habits, routines, and TODOs — was the core challenge. Balancing flexibility with simplicity in the UX took several iterations. I also intentionally used a production-grade tech stack to practice real-world patterns, including simple CRUD implementation and Rails MVC design.
