At Zen8labs, I have developed and maintained two products for Vingroup: the VinUni and My Vinmec applications. For VinUni is a mobile application designed to support students, faculty, and staff by providing features such as news updates, event management, and payment services. For My Vinmec involved migrating the entire platform from EC2 to Kubernetes (EKS) in AWS Cloud, improving scalability and performance. Additionally, I support development teams in managing and operating CI/CD pipelines and infrastructure for both applications.

• Python / Django
• JavaScript / ReactJS
• Kubernetes / AKS / EKS
• Azure Cloud / AWS

I worked as a product engineer, handling a wide range of tasks, including developing features for both the frontend and backend, monitoring and analyzing product quality, and implementing improvements. Additionally, I developed CI/CD pipelines and led the migration of the platform from AWS to GCP.

• JavaScript / NodeJS / ReactJS
• AWS / GCP
• Terraform / Terragrunt

I worked as an backend engineer to develop a workout application.

• JavaScript / NodeJS
• Elastic Beanstalk, Simple Email Service in AWS

I developed internal tools to enhance performance and minimize deployment errors for development teams, integrating them with GitLab, Jira, and Kubernetes clusters. Additionally, I built and maintained GitLab CI pipelines, handled on-call monitoring, and investigated/resolved infrastructure issues reported by development teams.

• Kubernetes on private cloud
• Helm charts
• Prometheus / Loki / Jaeger tracing / Grafana
• Gitlab / GitlabCI

I worked as a Full-Stack Developer to build a marketplace application. For Backend, I developed a catalog service to manage products and related data, including catalogs, suppliers, brands, and attributes. For Frontend, I built a multi-tenant Next.js application for clients such as Phong Vu, Soi Bien, and Takashimaya. Additionally, I developed the frontend for POS and Smart POS systems at terminals. Additional, I trained interns and junior developers, optimized web performance, and reduced build time for the Next.js application. You can learn more about this project at my post
