At Systematic Functions, I lead infrastructure across an AWS and Azure SaaS platform serving eight subsidiaries. I built a shared internal platform for engineering teams, with EKS and AKS workloads and 99.99% uptime.
I developed the greenfield cloud foundation, including AWS landing zones, hub-and-spoke networking, and Terraform/Terragrunt modules for AWS and Azure. Automated tenant provisioning enabled zero-touch onboarding, and infrastructure changes reduced time-to-market for new tenant services by 40%.
At FPT Software, I designed a multi-tenant AWS lending platform using Terraform, CloudFormation, EKS, and GitOps. I also developed Python and Bash self-service tools and contributed to cloud cost initiatives that reduced AWS spend by 20%.
During my engagement with Vietnam Prosperity Bank (VPBank), I integrated a Loan Origination System with existing on-premises and AWS systems, helping cut end-to-end loan processing to about one minute per application. Earlier, at Vietnam Maritime Commercial Joint Stock Bank (MSB), I built and managed CI/CD pipelines, and at 1C Vietnam I developed customized solutions on the 1C:Enterprise platform.
