Case Study
Fitraat Focus - Deep Work System
A free, cross-platform deep-work practice with a 5-step loop, purpose-driven planning, and real session accountability.
One Expo codebase shipped across iOS, Android, and web built with Expo Router + Firebase.





The Practice Loop
Challenge
Deep work usually breaks before work starts: no preparation ritual, fragmented todos, and no session close to keep cognitive load contained.
Solution
Designed a 5-step loop (Prepare -> Activate -> Focus -> Close -> Reflect) with mandatory readiness pillars and session continuity so unfinished todos stay context-aware inside the current work block.
Results Shipped
- ✓Users move from intention to execution with less startup friction
- ✓Session flow keeps work bounded and easier to repeat daily
- ✓Reflection history improves consistency over time
Purpose Systems + Studio
Challenge
Most todo lists are isolated and unstructured, so users keep rebuilding work plans from scratch instead of following tested paths.
Solution
Built a companion Purpose System Studio where creators publish outcome-driven work as ordered sections and tasks. In the app, users take a copy and execute that system step by step.
Results Shipped
- ✓Reusable work systems replace random task lists
- ✓Clear handoff between authored structure and daily execution
- ✓Supports exam, craft, and career workflows in one framework
Cross-Platform Product Engineering
Challenge
Need to deliver identical product behavior on mobile and web while preserving security, observability, localization, and release reliability.
Solution
Owned product, design, and engineering end-to-end. Used one Expo tree for iOS, Android, and web; enforced server-side protection with Firebase + Cloud Functions; added Sentry/Crashlytics; and shipped through web + Play distribution.
Results Shipped
- ✓Single product system delivered across multiple platforms
- ✓Protected writes and stable runtime monitoring in production
- ✓English and Bangla support available throughout the experience
