Mason Wong

Hi, I'm Mason.

I'm a software engineer based in Hong Kong. Outside of software, I spend a lot of time playing basketball, training, learning about AI and markets, and thinking about risk, investing and how to make better decisions.

I spent five years building backend systems at Crypto.com. This site is where I keep track of what I'm learning, thinking about, reading, building and experimenting with over time.

What I'm doing now

Things I've built

  • Gomar.ai

    An AI gym coach and workout tracker I co-created and launched. It personalises workouts from training history, recovery, goals and equipment, with logging, progress tracking, offline support and a 1,300+ exercise library.

  • NBA Predictor

    A Go and Gin service with PostgreSQL that integrates NBA data behind a layered HTTP API, with Docker, database migrations, YAML configuration and graceful shutdown.

Interests

  • Basketball

    I play regularly and compete in games. It's a big part of how I spend my time outside work.

  • Gym & fitness

    I train regularly and like learning how to improve performance, strength and recovery.

  • Investing & trading

    I'm interested in markets, risk, trading psychology and, increasingly, how to avoid losing rather than only how to make more.

  • AI & technology

    I'm learning how AI is changing the way we build software, work and make decisions.

  • Building products

    I enjoy turning ideas into useful products and learning from actually putting them in front of people.

Work

Crypto.com, Aug 2021 – Jul 2026

  • KYC / EDD Platform

  • Crypto.com AI Assistant

    A Go feature-eligibility API covering 30+ product features, and a multi-stage intent pipeline where semantic matching handled around 90% of queries in roughly 15–30 ms.

  • Localization Platform

    Localization delivery across 20+ languages, reducing peak infrastructure and translation costs by roughly US$7,000 a month.
