Work History
Front End Developer
Monime Limited
08.2024 - Current
- Architected and developed scalable mobile applications using React Native and Expo for both iOS and Android, with production deployments on the Apple App Store and Google Play Store.
- Designed and implemented complex authentication flows, including biometric login, PIN-based access, and secure token handling, ensuring seamless and secure user onboarding.
- Built reusable UI components and modular state management systems, such as a filter registry, carousel-based account selectors, paginated data lists, and transfer/payment flow UIs, improving code maintainability and feature extensibility.
- Led integration of third-party financial and payment APIs, enabling real-time account management, transaction processing, and payout systems within mobile applications.
- Collaborated with designers and product teams to translate wireframes into pixel-perfect, high-performance interfaces with smooth animations and responsive layouts.
- Implemented clean architecture principles, abstracting business logic into hooks, context providers, and service layers to ensure future-proof, testable, and easily extendable codebases.
- Optimized build and deployment workflows using EAS (Expo Application Services), TestFlight, and Play Console, ensuring rapid iteration and continuous delivery.
Android Developer Intern
Monime Limited
08.2023 - 08.2024
- Architected and developed large-scale Android applications using Jetpack Compose with a fully multi-module structure (e.g. authentication, biometric, network, core-ui, design-system, data, feature-*), enabling faster builds and clear separation of responsibilities.
- Designed and implemented advanced authentication systems, including biometric login (Fingerprint/Face ID), PIN verification flows, secure session handling, and token persistence via Jetpack DataStore (replacing legacy SharedPreferences-based implementations).
- Built reusable composable UI components and a shared design system module, establishing consistent styling, typography, and interaction patterns across features.
- Implemented clean architecture using MVVM + Coroutines + Flow, structuring each module with clear data / domain / ui boundaries to maximize maintainability and testability.
- Integrated RESTful APIs and implemented offline resilience using Retrofit + Room + DataStore-backed session caching, ensuring authentication continuity even during network disruptions.
- Refactored legacy XML-based screens into Jetpack Compose, reducing boilerplate and significantly improving UI rendering performance.
- Diagnosed and eliminated performance bottlenecks using Android Profiler and Firebase Crashlytics — reducing recomposition overhead, memory leaks, and unnecessary recompute cycles in composables.
- Owned release and deployment pipelines, configuring Gradle, CI/CD, and Google Play tracks to automate build flavors (staging vs production) and ensure safe rollouts.
