Mobile Engineer

Converted legacy streaming modules into a reusable architecture, integrated live and on-demand playback, and validated releases through regression testing and post-release fixes.

Legacy refactoring reduced feature integration time by approximately 35%. Akamai, ExoPlayer, HLS/DRM, Firebase Analytics, and release validation.

Integrated Java and Kotlin modules to enable media processing, bridge debugging, and release support for React Native, as well as camera and video capabilities.

Camera2, OpenGL, FFmpeg, MediaMuxer, ExoPlayer, and WebRTC.

I used GraphQL functionality, integrated camera scanning and image-processing flows with ML Kit, and provided support for unit, user interface (UI), and regression tests.

Product reach: 100,000+ active users. Kotlin, ML Kit, GraphQL, Kakao, Espresso, and Mockito.

Focused on mobile hardening, transaction validation, encryption, biometrics, certificate pinning, and secure local storage.

AppDome Shield, SSL pinning, AES encryption, biometrics, and secure storage.

I designed image-to-NFT creation and wallet-connected marketplace capabilities on Polygon, along with application monitoring and production releases.

Camera2, ML Kit, MVVM, Firebase, in-app purchases, and Polygon.

Built an Android proof of concept for wallet creation, connection, transfers, and Polygon NFT minting, verifying the communication between the app, wallet, network, & smart contract.

Android, Kotlin, Solidity, MetaMask, Polygon, and Infura.

Customized local-network file transfers for Android phones and TV devices, with connection setup, transfer-state feedback, and navigation for both screen types.

FTP server/client, Android, Android TV, file handling, and local networking.

Built a desktop ADB controller with integrated QR pairing, network auto-discovery, and connection monitoring for Windows, macOS, and Android operating systems.

Kotlin, Compose, ADB, QR pairing, network discovery, and desktop packaging.

I incorporated Ethereum wallets into the process of buying event tickets. The mobile flow handles transaction confirmation, status tracking, and backend ownership verification.

Ethereum, wallet integration, REST APIs, and transaction verification.

Integrated Zebra barcode scanning with a local stock list. SQLite stored the scanned codes, and REST APIs provided product details when an item was selected.

Integrated mobile controls to smart devices through AWS IoT integration, local discovery, and remote commands, with a focus on connection handling and background reliability.

AWS IoT SDK, ESP32, BLE, TCP/IP and UDP discovery, Gson, and Firebase Performance.

I created an Android messenger that offers real-time chat, voice and video calls, local storage, and secure media management.

WebRTC, XMPP, WebSocket, Room, and offline synchronisation.

Developed and maintained voice-campaign communication workflows and backend integration, with an emphasis on asynchronous processing and mobile reliability.

SIP/VoIP, backend services, and Android background processing.

Created workflows for rider and driver booking, live tracking, fare calculation, and payments, using GraphQL APIs and real-time updates.

Google Pay, Paystack, Razorpay, Firebase, and location services.

Built rental marketplace features and enhanced image-loading performance by caching and resource handling.

Image loading improved by approximately 40% using Glide.

Built features for social and legal forums, with a focus on data handling in offline mode and improved synchronisation for applications backed by Firebase.

Data sync latency reduced by approximately 30%.

Built reusable Android architecture modules, file-transfer utilities, and authentication helpers to simplify integration across projects.
