   Gurgaon · Full time

   Senior Software Engineer @ Dario Health

   Dario Health Android app

   • Worked on the flagship Dario Health Android app on Google Play (opens in a new tab), a healthcare app with 1L+ (100,000+) downloads and active users.
   • Owned security for patient health information (PHI): field-level Firebase encryption, encrypted local storage and secure Amazon S3 media access.
   • Wrote root and emulator detection in C/C++ with the Android NDK, so the app could block use on compromised devices.
   • Built the GLP Screening flow (10+ screens) for the GLP-1 program, plus multilingual onboarding and consent flows.
   • Re-architected the native Chat feature.
   • Accessibility to WCAG 2.1: Compose Semantics, TalkBack, VoiceOver, focus order, touch targets and dynamic font scaling.
   • Modernized legacy parts of the app toward Kotlin, Jetpack Compose, Clean Architecture and modular features.
   • Built native Android modules and bridges for React Native host apps.
   • Took part in architecture and design reviews, PR reviews, and performance and stability work in Agile/Scrum sprints.

   Dario Journey SDK (Kotlin Multiplatform)

   • Architected a Kotlin Multiplatform + Compose Multiplatform SDK for Android and iOS, sharing business logic, state, networking and UI, built with Ktor, SQLDelight and Koin.
   • Designed the SDK: DSL configuration API, core journey engine, MVI state layer, Compose renderers, design system and platform abstractions (media, analytics, image loading, deep links, auth).
   • Shaped the public API so host apps, native or React Native, could plug in their own media, analytics, image loading, deep links and authentication.
   • Built the Discover module in Compose Multiplatform (MVI/UDF, Coroutines, Flow), shipped on Android and iOS from one codebase.

   AI-assisted engineering

   • Contributed to an internal AI developer agent that turns PRDs and codebase context into technical approaches, Confluence docs and Jira tasks, always reviewed by engineers.
   • Daily AI-assisted development with Cursor, Claude, Claude Code, Gemini, GitHub Copilot, ChatGPT, Codex and MCP, with every change reviewed before it ships.

   • Designed and ran MVVM and Data Binding training for 50+ engineers, from freshers to managers, supporting the move away from legacy MVC code.
   • Developed Galaxy Watch Contacts features, including the Emergency Contacts logic and wearable UI/UX.
   • Improved touch targets and interaction behaviour for small wearable screens, with accessibility in mind.
