Product Leader × AI Builder — Bangkok
I'm Sarun Saengsomboon — around 20 years across product management, UX, and engineering. I shape product strategy, design the experience, and build with AI — from first concept to real, shipped product.
body/18 · Inter · max-w-xlCurious how this page is built? — like any good design system.
I'm a technology and digital product professional with around 20 years of experience across software development, system analysis, UX/UI design, product strategy, team management, and business operations. My career started in software development — web applications, backend systems, databases, and internal business platforms — and over time I expanded into system analysis, UX/UI design, product management, and leadership, giving me a strong ability to understand both technical requirements and business goals.
I've worked on a wide range of digital products: web platforms, mobile applications, back-office and POS systems, KYC, FinTech platforms, blockchain and DeFi applications, chatbots, LINE OA integrations, and automation workflows. Since 2023 I've actively integrated AI tools — ChatGPT, Claude, and Claude Code — into my daily workflow to support product research, UX thinking, documentation, rapid prototyping, and building production-ready applications, moving faster from idea to prototype, and from prototype to real product.
My strength is the ability to connect business, user experience, technology, and execution. I work closely with founders, executives, clients, designers, developers, and compliance teams to translate ideas into practical digital products — and I enjoy work that needs both strategic thinking and hands-on execution, especially across AI-enabled products, UX/UI systems, FinTech, blockchain, automation, and scalable SaaS.
