👋 I'm Valentin Kao

Senior Software Engineer with a focus on AWS cloud solutions, serverless backends, and AI-driven applications. I architect and deliver robust, scalable platforms, leveraging AWS (Lambda, DynamoDB, API Gateway), Node.js, and Next.js to solve real business problems.

Originally from Toulouse, France 🇫🇷, I help teams move fast by integrating AI (custom assistants, code reviewers, simulators) and building future-proof cloud infrastructure.

When I’m not building software, I’m recharging with Muay Thai 🥊, lifting, or running.
