About

I'm a serial entrepreneur, tech enthusiast and experienced fullstack developer with strong background in Math / Blockchain & Smart contracts / Machine Learning / Algorithmic trading. Previously worked as an exotic options trader / structurer and built real-time trading and risk management platforms from scratch. Currently based in London, UK, building and scaling VTVL's token asset management platform to revolutionise vesting, ownerships and liquidity to empower Web3 founders, investors and their communities and DAOs. I had built the tech consulting company Sanuker Group (now part of Green Tomato Group) and had worked on over 30 projects ranging from web applications, e-commerce site, mobile apps, building real-time system for bookings, business analytics intelligence and messenger-related development (messenger apps and chatbots). My other venture Cove was a Hong Kong based car-sharing platform and was invested by InMotion (investment arm of Jaguar Land Rover Group) and the business now evolved to mobility data analytics to provide high quality driving data for autonomous driving model training. I held a master degree in computer science and have extensive knowledge and experience in computer vision and machine learning. Practical development experience in React, Next.js, React Native, Node.js, Solidity, Typescript, Go, Python, Scikit-learn, Keras, Tensorflow. I am also a tech educator and host programming and blockchain trainings in Hong Kong with private institutions and in the public sector.
