Thank you, Qasem, for your exceptional service!" 🚀 SENIOR MOBILE & AI ENGINEER | 9+ YEARS | FLUTTER · iOS · RAG SYSTEMS 👋 Hi, I'm Qasem. I build production mobile apps and the AI systems behind them — from Flutter and native iOS products with hardware integrations, to RAG-based assistants that ship and get measured. Most developers do one or the other. I do both, which means I can take an AI product from retrieval pipeline to polished mobile UI without handing off between teams. 🤖 AI & RAG ENGINEERING - End-to-end RAG pipelines: chunking, embeddings, hybrid retrieval, reranking, query rewriting - Vector search and knowledge base design — enrichment, variant generation, freshness management - Production AI support agents: live email handling, multi-tier triage, human escalation paths - LLM integrations across major providers, plus local/offline models via Ollama for air-gapped and privacy-sensitive deployments - Agentic workflows — multi-step agents, tool use, structured outputs, evaluation harnesses and guardrails for compliance-sensitive domains - Admin dashboards and analytics so stakeholders can see what the AI is actually doing 📱 MOBILE DEVELOPMENT - Flutter & Dart — Clean Architecture, BLoC/Cubit, Provider, Riverpod - Native iOS — Swift, SwiftUI, UIKit, RxSwift/RxCocoa - Native Android — Kotlin, Jetpack Compose - React Native - BLE / hardware-connected apps across multiple shipped consumer devices - E-commerce and subscription commerce integrations - CI/CD, automated testing, E2E test automation, App Store & Play Store release management 💡 SELECTED WORK - AI support platform — RAG-based customer support system for a consumer wellness product line. Enterprise email integration, multi-tier triage, compliance guardrails, analytics dashboard. Benchmarked against leading commercial AI support tools. - Offline AI desktop assistant — Flutter desktop assistant for a security-sensitive enterprise environment, running fully local. Zero data leaves the machine. Clean Architecture, phased delivery. - AI developer workflow CLI — my own product: an AI-driven CLI automating mobile development workflows including design-system extraction, feature implementation, bug triage, and QA automation, across Flutter, SwiftUI, Compose, and React Native. - Connected-device companion apps — consumer health hardware with BLE pairing, firmware handshakes, session tracking, and subscription billing. - Real-time communication app — native chat with text, voice, and video calling over WebSockets. - Live event platform — Flutter app for event hosting with real-time voting at scale. 🔥 HOW I WORK Direct communication, no surprises. I scope honestly, tell you when an approach won't work, and ship on the timeline we agreed. I've led mobile teams and worked solo — both fine. Comfortable owning architecture decisions or slotting into an existing codebase and matching its conventions. 📈 LET'S TALK Whether you need a mobile app built from zero, an AI assistant that gives real answers instead of generic ones, or an existing product taken to production grade — send me the details and I'll tell you honestly whether I'm the right fit.
