Executive Summary

Technical Architect and former CTO with 15+ years leading engineering teams and partnering with business leaders across Asia. I specialize in modernizing legacy ecosystems, designing cloud-native, event-driven architectures, and aligning technology decisions with commercial priorities, regulatory constraints, and operational realities.

I operate at the intersection of business strategy and technical execution — translating complex requirements into scalable systems, shaping product direction, and enabling organizations to deliver faster with lower risk. Known for cross-functional influence, I help business, product, and engineering teams converge on clear decisions, predictable delivery, and measurable outcomes.

Most recently I've focused on AI-enabled decisioning — architecting an AI-assisted underwriting solution, integrating an AI underwriting decision engine with a chatbot, and contributing to the AI security and governance of these initiatives.

Core Capabilities

AI & Intelligent Systems

  • AI security & governance: defining the perimeter of where AI can be applied — what it can and cannot do — and establishing technical and functional guardrails for AI-assisted decisioning
  • AI/LLM integration into business-critical workflows (AWS Bedrock, Claude)
  • AI-assisted underwriting decisioning — from solution architecture to integration
  • Conversational AI: connecting AI decision engines with chatbot interfaces
  • Bringing emerging AI capabilities into existing enterprise systems

Architecture & Technology Strategy

  • Modern software architecture: microservices, event-driven, CQRS, Event Sourcing, DDD
  • Legacy-to-modern migration aligned with business priorities
  • Cloud-native design on AWS with Infrastructure as Code (Terraform)
  • API ecosystems, distributed systems, and domain modeling
