Qasim A.

If you need an Android engineer who can own the full technical scope — architecture, AI integration, real-time streaming, and Play Store delivery — I've done all of it in production. 7 years of senior Android engineering. My recent work includes: → A RAG-based AI Android app where users upload PDFs, books, and images — stored as vector embeddings in a backend DB — and the app answers questions from their own data with zero hallucination. I handled system design, Android development, PaddleOCR setup, vector DB, and cloud infrastructure. → A live streaming Android SDK migration from ExoPlayer to Media3 (Jetpack), with custom MediaSource pipelines and adaptive bitrate streaming in a production app. → A 3-app platform (user, provider, store) for a US home services company — real-time socket communication, multilingual support, payment integration, and full Play Store deployment. Currently live and in final launch phase. → SDK 35 Play Store compliance for a US client — including decompiling a proprietary JAR with no source code available, rebuilding the problematic classes from scratch with the same package and method signatures, and getting both apps approved. What I bring to every project: Clean Architecture + MVVM — UI fully decoupled from business logic. No shortcuts that become your problem later. Real-time first — socket, TCP/UDP P2P, Agora, WebRTC. I've built communication layers from scratch when SDKs didn't fit the use case. AI-ready Android — RAG pipelines, LLM integration, on-device ML with MLKit. This is where Android is heading and I'm already building here. Play Store expertise — SDK upgrades, compliance fixes, rejection resolution, and full submission management.
