Technical Architect & Engineering Leader: Modern Systems & Business-Aligned Architecture

Hong Kong SAR • [email protected] • +852 9730 0150 • linkedin.com/in/olivierbregeras

Executive Summary

Technical Architect and former CTO with 15+ years leading engineering teams and partnering with business leaders across Asia. I specialise in modernising 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 organisations 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 have 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 modelling
