I build resilient cloud platforms and automate production systems across fintech, trading, defense, and healthcare.
SingaporeWhat I'm looking for
I'm helping WhyLoop accelerate DevOps transformation so teams can deliver high-quality software that remains reliable, accessible, and scalable for customers.
At R3, I brought the Corda Network's production and pre-production environments to life and made its first-ever transaction. I later helped future-proof the platform by migrating its ledger from MySQL Galera to CockroachDB and exploring Corda deployments on Kubernetes.
As a Senior Staff DevOps Engineer at R3, I shared Corda 4 platform and codebase knowledge with new hires while contributing to Corda 5.
I've also designed distributed compute and storage clusters for trading research, automated server deployments, and maintained zero-single-point-of-failure network and data-centre infrastructure. Across cloud and on-premises systems, I use infrastructure as code, Kubernetes, automation, and pragmatic engineering to align technology with business goals.
