Summary
Valentin Kao is a pragmatic software engineer with 9 years of experience building cost-effective, production-ready backends and cloud architectures for startups and IoT platforms. An AWS Certified Solutions Architect, he specializes in serverless-first designs (Lambda, DynamoDB, EventBridge) while knowing when to move to containers (ECS) for performance and cost control. He’s shipped large-scale IoT systems and multi-tenant APIs, led engineering teams to ISO 27001 certification, and cut AWS costs dramatically through observability and architectural audits. Recently he’s acted as the technical bridge for GenAI products—integrating OpenAI/Bedrock, LiveKit and ElevenLabs into realtime workflows without bankrupting the business. Equally comfortable in TypeScript/NestJS, Python/FastAPI and React/Next, he pairs hands-on implementation with infrastructure-as-code (Terraform, CDK, SAM) to avoid future rewrites. Based in Hong Kong, he blends startup velocity with disciplined platform thinking and a habit of designing for observability and predictable costs.
