About
Hi, I’m Kian Hean. I’m a platform engineer in Singapore, and I’ve spent about 15 years in places where things really can’t go down: exchanges, index providers and trading tech.
Right now I’m a Principal Platform Engineer at Trading Technologies. I look after the AWS setup that live trading systems run on (30+ accounts across 3 regions), the CI/CD that ships hundreds of deploys a week, and the dashboards and alerts that tell us when something’s off, ideally before anyone else notices.
I took a slightly odd route here. I spent my first eight years writing Python for finance at SGX and IHS Markit, building index engines, backtesting tools and portfolio optimisation. Some of that became real products, like the SGX APAC REIT Index. So when I’m running infrastructure, I usually know what the systems on top of it are actually doing.
I still like writing actual code, not just YAML, which is how the apps and Home Assistant bits above came about.
Usually reaching for: AWS, Terraform, GitHub Actions, Kubernetes, Prometheus, Grafana, Python and React.
Always happy to chat about platform engineering, reliability, or where finance and infrastructure meet.
