CBT Companion is a comprehensive mental health application that provides users with evidence-based Cognitive Behavioral Therapy tools and techniques accessible directly from their mobile devices. The platform serves as a digital therapeutic solution that helps users identify negative thought patterns, challenge cognitive distortions, and develop healthier coping mechanisms. This user-centered application makes professional-grade mental health resources available to everyone, supporting users in managing anxiety, depression, stress, and other mental health challenges through guided exercises and tracking tools.

- The app features a diverse collection of CBT exercises including thought records, behavioral activation tools, cognitive restructuring activities, and guided journaling prompts designed by mental health professionals.

- Interactive mood and symptom tracking capabilities allow users to monitor their emotional states over time, identify triggers, and recognize patterns in their mental health journey.

- Personalized guidance and educational content provide users with relevant information about their specific challenges, helping them understand the connection between thoughts, feelings, and behaviors.

- CBT Companion was built using React Native framework with JavaScript/TypeScript, enabling a single codebase to deliver native performance and consistent user experience across both iOS and Android platforms.

- The application architecture implements Redux for centralized state management with Redux Saga middleware handling complex asynchronous operations and side effects throughout the therapy experience.

- Secure data handling was achieved through a combination of AsyncStorage with encryption for local data persistence and Firebase for authenticated cloud synchronization, ensuring HIPAA-compliant protection of sensitive mental health information.

- I architected and developed the complete React Native application, creating a unified codebase that delivers native performance and accessibility on both major mobile platforms.

- I implemented complex interactive therapy tools including cognitive restructuring exercises, mood tracking visualizations, and guided meditation features with audio integration.

- I built a robust offline-first architecture ensuring users maintain access to their therapy tools and personal data even without internet connectivity, critical for consistent mental health support.

- The application has reached over 100,000 downloads on Google Play alone with a strong 4.4-star rating from more than 3,300 user reviews, demonstrating significant impact in the digital mental health space.

- The React Native implementation achieved excellent performance metrics while maintaining a single codebase, significantly reducing development time and enabling rapid feature iteration based on user feedback and clinical insights.

- The successful development of CBT Companion led to the creation of additional therapeutic applications by Resiliens, including DBT Coach and ACT iCoach, expanding the company's mental health technology ecosystem.
