Available to hire
Hi, I’m Jin Kyu Ng Kim, a full-stack developer and DevOps engineer with 3+ years of production experience spanning blockchain, DevOps, and front-end development. I’m currently building blockchain audit trail systems and CI/CD pipelines on AWS.
Previously, I deployed 4k+ NFTs on the Polygon mainnet for copyright protection, and I am experienced with YAML-based configurations, infra tooling, and structured data workflows. I am pursuing a Master’s in Enterprise Software Development at the University of Technology Sydney (UTS) to combine advanced software skills with hands-on delivery.
