About Yongky

I design, automate and optimise large-scale cloud infrastructure that stays secure, reliable and affordable.

I am a Senior Cloud & DevOps Engineer with 7+ years of designing, automating and optimising cloud infrastructure across AWS, Azure, GCP and Alibaba Cloud. I lead cloud migrations and reliability work, and build on Kubernetes, Terraform and GitOps pipelines.

Most of my work is for regulated financial workloads, where cost, resilience and security all have to hold at once. Rightsizing, automation and better observability have delivered $14k/month in savings, and I bring DevSecOps, SRE practice and ISO 27001 compliance into every change while mentoring the engineers around me.
