At Sandbox, that means evaluating acquisition targets, modelling the economics and presenting an investment case, then spotting where a better tool can improve the process. I built an internal deal-management platform now used by three colleagues. As a founder, I took Kiroku Notes from an idea to an AI-enabled learning platform and raised US$100k in pre-seed funding. That taught me to turn ambiguity into a plan, pitch it clearly, and take ownership of execution. I also bring calm operational discipline: during national service, I managed supplies for roughly 1,500 soldiers and trained around 80 recruits. I can move between analysis, software and people without losing sight of the outcome."}]},{"question":"What AI tools do you use the most?","url":"https://saywise.com/q/10c2b363a976","answers":[{"title":"Post","url":"https://saywise.com/s/b789eb1f9c06","text":"Codex and Claude are the tools I use most for building. I used them to create Sandbox's internal acquisition CRM: translating a corporate-development workflow into a working platform that supports outbound sourcing and deal management for three colleagues. My starting point is the problem, the users and the acceptance criteria. I use AI to move faster through implementation and iteration, while keeping ownership of the business logic and the quality of the result. I'm especially interested in the overlap between AI, learning and practical operations. At Kiroku Notes, I built an AI-enabled learning platform around spaced repetition, adaptive difficulty and gamified progression. My studies in data science, machine learning and NLP help me connect the tools to the ideas behind them."}]}]},"work":[{"name":"Radiant Management Systems","position":"Co-Founder and CEO","location":"London, UK","url":"https://prayerfirst.sg","startDate":"2026-05-01","summary":"Building and shipping consumer apps including Prayer First (Bible-led focus and app blocking), TriElite (triathlon training), and Unknot (guided stretching).
