Android Developer, pagerduty Jan 2025 – Present Remote, USA

• Engineered incident management features for the PagerDuty Android application using Kotlin, Clean Architecture, and Hilt dependency injection, enabling DevOps engineers to efficiently acknowledge alerts and manage on-call workflows.

• Implemented structured background job processing using WorkManager and DataStore, enabling reliable synchronization of alert data and preferences while maintaining stable application behavior during intermittent network connectivity scenarios.

• Improved incident timeline rendering efficiency by 34% by optimizing Kotlin Coroutine concurrency models and paging mechanisms, enabling faster retrieval and display of operational alert history across production environments.

• Designed modern mobile interfaces using Jetpack Compose and animation APIs, allowing engineers to visualize service health signals and operational alerts through interactive dashboards within the mobile monitoring platform.

• Developed REST-based mobile service integrations using OkHttp networking pipelines and JSON serialization, enabling secure communication between the Android client and PagerDuty’s distributed incident management services.

• Reduced application crash occurrences by 29% through proactive debugging practices using Android Studio profiler, Gradle build optimization, and structured error monitoring pipelines across production mobile releases.

• Strengthened secure mobile authentication by integrating encrypted token management and identity validation workflows, increasing successful enterprise mobile login reliability by 22% across active PagerDuty engineering users. Android Developer, HCL Tech May 2022 – Jul 2023 Indore, India

• Developed scalable enterprise Android applications using Java, Android SDK, and MVVM architecture, enabling business teams to streamline workflow approvals, operational reporting, and internal service management processes.

• Built dynamic user interfaces using ConstraintLayout, RecyclerView, and custom UI components, enabling enterprise users to efficiently access dashboards, operational data records, and workflow management tools.

• Integrated enterprise backend systems through Retrofit-based RESTful API services, enabling secure data exchange and consistent synchronization of transactional records between Android applications and enterprise service platforms.

• Implemented mobile data persistence using SQLite and Room Database layers, enabling offline operational capabilities for distributed employees working in field environments with limited network availability.

• Established structured application navigation flows using Activity lifecycle management, Fragment architecture, and Navigation Components, improving usability consistency across enterprise Android application modules.

• Improved application startup and transaction processing performance by 31% by optimizing API request handling, background processing tasks, and structured data caching strategies across core Android modules.

• Managed mobile application releases through Google Play Store deployment pipelines, implementing versioning, app signing, and monitoring through Firebase Analytics and Crashlytics, reducing production defects by 25% after major releases. Education
