Migration from XML-based UI

Software Engineer
Software Engineer
  • Led the migration from XML-based UI to Jetpack Compose, improving UI rendering performance by 40%, measured using Android Profi ler and Systrace, while reducing boilerplate code and accelerating design iteration cycles
  • Implemented Remote Therapeutic Monitoring (RTM) feature, enabling clinics to get paid for monitoring patient data. This led to a 25% increase in clinician app usage (via Mixpanel and Firebase Analytics) and unlocked a new revenue stream
  • Built automated CI/CD workfl ows with GitHub Actions and Fastlane to streamline QA processes and enable continuous testing
  • Integrated Mixpanel analytics across critical user journeys, enabling deeper insight into user behavior and driving improvements in feature adoption
  • Provided mentorship and code reviews for junior developers, fostering a culture of technical excellence and growth
  • Delivered scalable features with Kotlin and MVVM Clean Architecture, powering a patient-focused product used by 10K+ active users across B2C and B2B markets across the U.S
  • Designed and consumed REST APIs for collecting on-device sensor and gait data, ensuring reliable background data capture and transmission to the server with minimal battery impact
  • Contributed to server-side data processing logic to aggregate patient activity data into structured reports, giving clinicians clear, actionable insights per patient session
  • Embedded Claude, Cursor, and Codex into daily development workfl ows to automate repetitive tasks ? from generating boilerplate to writing test cases ? cutting routine coding time signifi cantly
