👋 Hi, I'm John Bayar

Senior Mobile Architect & AI Engineer Bridging the gap between polished Mobile UX and scalable Generative AI Infrastructure. Based in Sydney 🇦🇺

🚀 Current Focus: Building Multi-Agent Orchestration Platforms on AWS using FastAPI & Next.js. I specialize in architectures that don't just "wrap" APIs but manage complex state, security, and scale.

🛠 Tech Stack:

  • AI/ML: Python (FastAPI), LangChain, Multi-Agent Systems, Ollama (Local LLMs), CoreML
  • Mobile: Swift, SwiftUI, Objective-C, Flutter (13+ years exp)
  • Cloud: AWS EC2, Supabase (PostgreSQL), Docker, Nginx

🏆 Highlights:

  • ROMA: Architected a Multi-Agent GenAI platform enabling dynamic model chaining (DeepSeek, GLM) with a custom "Logic" configuration UI.
  • Enterprise Mobile: Built Mongolia's #1 Ridesharing & Food Delivery apps (1.5M+ users).
  • Optimization: Reduced API costs by 95% for high-volume location services.
