Second-time founder and technologist who began as a game developer before moving into startup and financial services leadership. Was CTO and co-founder of Stayr/Staytion, a Southeast Asia prop-tech and travel startup that scaled to $1M ARR in Year 1 and $3M ARR in Year 2 before being acquired. After the exit, identified the gap in reliable AI backend tooling and founded JigsawStack in January 2024.
