About

Building systems that scale

DevOps engineer and full-stack developer focused on reliable infrastructure, automated delivery, and polished user experiences.

I'm Pheng Bunath — a DevOps Engineer and Full-Stack Developer who bridges infrastructure and application development. I design CI/CD pipelines, deploy containerized workloads, and build interfaces that users love.

Currently a fourth-year Computer Science student at the Royal University of Phnom Penh, I've completed intensive training at the Korea Software HRD Center where I delivered production projects across DevOps, backend, and frontend domains.

  • CI/CD pipelines with Jenkins, GitHub Actions & Argo CD
  • Container orchestration on Docker & Kubernetes
  • Full-stack development with Next.js, React & Spring Boot
  • Infrastructure automation with Ansible & Linux

English Club: E-Learning Management System
Full-Stack
Case Study 01

English Club: E-Learning Management System

Problem

Learners needed a unified platform to register, access courses, take quizzes, and track progress—without fragmented tools or insecure access.

Solution

Built an end-to-end learning platform with JWT-authenticated REST APIs, role-aware dashboards, and a responsive Next.js frontend for seamless course consumption.

Architecture

Next.js frontend with NextAuth JWT sessions, RESTful API integration, server-side rendering for performance, and modular page routing for courses, quizzes, and progress tracking.

My Contribution

  • Integrated frontend with backend RESTful APIs and ensured smooth data flow
  • Implemented JWT authentication with NextAuth
  • Built user onboarding, course consumption, and progress tracking flows
  • Collaborated with backend team on API contracts and error handling

Results

  • Complete E2E learning flow from registration to progress tracking
  • Secure authenticated access across all user journeys
  • Responsive UI built with TypeScript and Tailwind CSS

Case Study 02

SmartOps: Automation Platform

Problem

Manual deployments were slow, error-prone, and lacked traceability from source code to production environments.

Solution

Designed a GitOps-first automation platform covering the full deployment lifecycle with CI/CD pipelines, container orchestration, and infrastructure as code.

Architecture

Jenkins and GitHub Actions for CI, Argo CD for GitOps delivery, Docker/Kubernetes for runtime, Ansible for provisioning, and Prometheus/Grafana for observability.

My Contribution

  • Built CI/CD pipelines with Jenkins and GitHub Actions
  • Implemented GitOps workflows with Argo CD
  • Containerized workloads and deployed on Kubernetes
  • Automated infrastructure provisioning with Ansible

Results

  • Automated deployment lifecycle from repo to production
  • Faster, more reliable releases with full traceability
  • Reduced manual intervention and deployment risk

Case Study 03

Selamounty: Digital Cultural & Educational Hub

Problem

Cultural institutions needed a scalable digital platform to deliver rich media content and educational experiences to a global audience.

Solution

Delivered backend services and deployment automation for a virtual museum platform with resilient APIs and automated rollouts.

Architecture

Spring Boot microservices with MySQL persistence, Jenkins CI/CD pipelines, Docker containerization, and Nginx reverse proxy for production traffic.

My Contribution

  • Built and maintained Spring Boot API services
  • Set up automated deployment pipelines with Jenkins and Docker
  • Configured Nginx for production traffic routing
  • Ensured reliable rollout for media-rich experiences

Results

  • Scalable platform serving global visitors
  • Automated deployments with minimal downtime
  • Reliable API layer for content delivery
