About

Software Engineering Lead with over 10 years of experience spanning diverse domains including Web, Mobile, VR, and Blockchain. My career demonstrates a proven track record with industry giants like True Digital Group and PTTEP, as well as scaling high-growth startups like Zanroo from inception to Series-A funding. Currently leading a team of 7-10 developers, I am passionate about evolving traditional development workflows by integrating AI-driven architectures (MCP, Sub-agents) to maximize efficiency. I thrive in collaborative environments and am seeking to join a team of talented, positive-minded professionals where we can push technological boundaries together.
