Android Development:

• Proficient in Android app development with extensive experience building and maintaining production applications across on-demand delivery, fintech, AI-driven consumer apps, and IoT platforms.

• Strong understanding and practical application of architectural patterns including MVVM, Clean Architecture (UseCases, Repositories), and multi-module design for scalable, maintainable codebases.

• Expertise in Android Jetpack and Architecture Components such as ViewModel, Navigation, Room, DataStore, WorkManager, and Paging to build robust and responsive applications.

• Hands-on experience with Jetpack Compose and Compose Multiplatform (CMP), including hybrid architectures where XML/Fragment and Compose screens share unified navigation, DI, and data layers.

• Led Kotlin Multiplatform (KMP) migrations for mission-critical apps, including shared networking (Ktor), persistence (Room/DataStore), and cross-platform business logic between Android and iOS.

• Proficiency integrating third-party services and APIs such as Firebase (Messaging, Crashlytics, Remote Config), Google Maps, Socket.IO, Apollo GraphQL, Billing Client, and AWS IoT Core (MQTT/TLS).

Kotlin Multiplatform / Cross-Platform:

• Led end-to-end KMP migration of a production courier app, sharing business logic, networking, and persistence across Android and iOS.

• Built hybrid architectures where native XML/Fragment screens and Compose Multiplatform UI coexist behind shared navigation, DI, and domain layers.

• Migrated networking and storage stacks to multiplatform-ready solutions (Retrofit → Ktor, multiplatform Room & DataStore) while keeping release cadence uninterrupted.

• Coordinated Android/iOS platform teams on shared contracts, error handling, telemetry, and feature-by-feature DI migration (Hilt → Koin) without blocking delivery.

Programming Languages:

• Mastery in Kotlin and Java, with deep understanding of language features, idiomatic usage, and modern Android best practices.

• Competent in Kotlin Coroutines and Flow for asynchronous operations, reactive streams, and concurrency-safe architecture.

• Experience with C/C++ for performance-critical and low-level system interactions.

• Familiarity with Python for scripting, automation, and backend-related tooling; exposure to Swift in KMP/iOS collaboration contexts.

• Object-Oriented Programming (OOP) Concepts:

• Strong grasp of OOP principles such as encapsulation, inheritance, and polymorphism, enabling modular and reusable designs.

• Proficiency applying design patterns (Singleton, Factory, Observer, Adapter, Repository) and SOLID principles for scalable architectures, including DI migration strategies (Hilt ↔ Koin).

• Data Structures and Algorithms:

• Solid understanding of fundamental data structures including arrays, linked lists, trees, graphs, and hash tables.

• Proficiency in algorithm design and analysis for sorting, searching, and performance-critical mobile scenarios such as batching, throttling, and offline sync pipelines.

Database Systems:

• Hands-on experience with Room and SQLite on Android/KMP, including schema design, migrations, CRUD operations, and offline-first synchronization.

• Experience with Preferences DataStore for typed local persistence, and familiarity with MySQL/PostgreSQL in backend-adjacent workflows.

• Operating Systems:

• Proficient in Linux, Windows, and macOS for day-to-day development, tooling, and environment setup.

• Familiarity with Docker and virtualization for containerized development and deployment workflows.

Networking and Protocols:

• In-depth understanding of TCP/IP, HTTP/HTTPS, WebSockets, and real-time communication patterns for mobile clients.

• Experience implementing Socket.IO pipelines with reconnection, watchdogs, and chunked batching; MQTT over TLS with AWS IoT Core and X.509 authentication; REST/GraphQL clients via Retrofit, Ktor, and Apollo.

• Background in industrial protocols including Modbus RTU and Modbus TCP/IP from IoT/SCADA projects.

• Development Tools and Methodologies:

• Expertise in Git workflows, branching strategies, pull requests, and collaborative code review practices.

• Proficient with Jira, Slack, and Agile/Scrum (including prior Scrum Master experience) for cross-functional delivery.

• Experience with Android Studio and IntelliJ IDEA for debugging, profiling, refactoring, and multi-module/KMP project management.

• Embedded Systems & IoT:

• Experience integrating mobile apps with IoT devices and smart appliances, including sensor/location pipelines, geofencing, and cloud-connected device communication (Wi-Fi, Bluetooth, MQTT).

• Familiarity with embedded-adjacent concepts such as device connectivity, certificate-based auth, and real-time telemetry.

Web Technologies:

• Working knowledge of HTML, CSS, and JavaScript sufficient for collaborating with web and backend teams on APIs, deep links, and hybrid features.
