AI Architecture

  • Multi-agent swarm orchestration
  • A2A protocol implementation (Google standard)
  • LLM-agnostic — Claude, GPT, Gemini, Copilot, multi-provider
  • Agentic loops with native tool use
  • System prompt architecture
  • Semantic filtering + density governor
  • Memory persistence with auto-compression
  • Multi-provider AI proxy (zero client-side keys)
  • Multi-model AI routing from single backend

Full-Stack Production

  • React 19 / TypeScript / Vite
  • Python (FastAPI) / Node.js / Express
  • React Native + Expo → shipped to App Store
  • Turso edge database / SQLite
  • Railway cloud deployment
  • Stripe / RevenueCat / PayPal / Square
  • Freemium architecture + subscription entitlements

Cybersecurity

  • API key isolation (zero client-side secrets)
  • Threat detection + link scanning
  • Agent-level access control
  • Incident response

Quant / Fintech

  • Python / pandas / numpy / yfinance
  • Quantitative signal design
  • Market regime detection
  • Position sizing + adaptive risk allocation
