Looking to build autonomous AI systems or integrate intelligent, production-grade LLM features into your mobile product? 🚀 I am a Senior AI & Mobile Systems Engineer with 6+ years of experience and $50K+ delivered on Upwork. I specialize in building autonomous agentic workflows, multi-model architectures, and deploying responsive, low-latency AI experiences to iOS, Android, and the cloud. Most developers either build basic mobile UIs or write unoptimized Python scripts. I bridge both worlds: designing intelligent backend AI pipelines and embedding them into high-performance, battery-conscious mobile applications. AI Agents & Autonomous Systems • Multi-Agent Architectures: Building autonomous workflows with LangGraph, CrewAI, and custom event loops • Tool Calling & Function Calling: Enabling models to execute native code, call external APIs, query databases, and return strict JSON schemas • Memory & Context Management: Session persistence, context window compaction, and vector retrieval (RAG) • Guardrails & Reliability: Structured outputs, fallback routing, and hallucination reduction AI-Powered Mobile & Multimodal Apps • Real-time streaming LLM generation via WebSockets / Server-Sent Events (SSE) • Multimodal interfaces: Voice-to-voice agents, real-time camera/vision feeds, and audio transcription (Whisper) • On-Device / Edge ML: Fast, private, offline inference with LiteRT (TensorFlow Lite) and MediaPipe • Production Mobile Architecture: Flutter (Bloc / Riverpod, Clean Architecture), Native MethodChannels (Swift / Kotlin) Foundation Models & Production Infra • Models: OpenAI (GPT-4o, o1), Anthropic (Claude 3.5 Sonnet), Google Gemini 1.5/2.0, DeepSeek • Backend & APIs: Python (FastAPI), Node.js, Firebase, Supabase (pgvector), AWS • Cost & Speed Optimization: Model tiering, token caching, prompt compression, and low-latency streaming Proven Track Record ⚡ • $50,000+ earned with 2,500+ hours logged on Upwork • 50+ production apps and AI systems delivered globally • Enterprise-grade code quality, maintainability, and clean architecture Whether you're building an autonomous agent from scratch, creating a conversational voice assistant, or integrating AI into an existing mobile codebase:
