⏰ 10K+ Hours worked ✅ 7 Projects Completed ⭐ 5 Stars Feedback I help startups and product teams turn manual, fragile infrastructure into repeatable, secure deployment systems. I work across Terraform, Ansible, Docker, GitHub Actions, Linux, Nginx, TLS, cloud networking, WireGuard, Redis, MongoDB, AWS, and DigitalOcean. My background is unusual for a DevOps / Platform Engineer: I came through both Network Engineering and Full-Stack Product Engineering. That means I understand the entire path: Network → Infrastructure → Linux → Containers → Application → CI/CD → Production ### What I can help you with • Infrastructure as Code with Terraform • Linux server provisioning and hardening • Ansible configuration management • Docker and containerized deployments • Docker Swarm environments and migrations • GitHub Actions CI/CD pipelines • Deployment automation and rollback workflows • Nginx reverse proxy and HTTPS/TLS configuration • DigitalOcean and AWS infrastructure • WireGuard private management networks • Server and application troubleshooting • Redis and MongoDB production environments • Infrastructure documentation and operational runbooks • Reproducible environment and disaster-recovery design ### Production engineering background From 2021 to 2026, I led engineering for CarmateKH, an automotive marketplace operating in Cambodia. I progressed from hands-on application development into technical leadership and production ownership across: • Next.js and React applications • Node.js backend services • MongoDB Atlas • Redis • AWS S3 • Nginx and PM2 • CI/CD and deployments • production troubleshooting • system architecture and technical handover That experience is why I approach infrastructure from the application team's perspective. I don't just ask, "Can the server run?" I ask: • Can another engineer reproduce it? • Can we deploy safely? • Can we recover after failure? • Are configuration and infrastructure documented? • Are secrets and management access properly separated? • Can the system be rebuilt without tribal knowledge? ### Recent Platform Engineering work I built a reproducible multi-node cloud platform using: Terraform → Ansible → Docker Swarm → WireGuard → GitHub Actions → GHCR → Nginx/TLS The project includes infrastructure provisioning, automated configuration, private CI deployment networking, immutable container releases, service health checks, failure testing, clean-room rebuilds, and idempotency validation. I also have experience leading cross-functional engineering delivery. I assembled and led a UI/UX designer, frontend engineer, and backend engineer to build CP Core, a reusable commerce platform covering storefront, admin operations, authentication, catalog management, cart, checkout, orders, Postgres, S3 media, and transactional email. ### Good fit I am particularly useful when: • deployments still depend on manual SSH commands • Docker environments need production structure • CI/CD is unreliable or missing • infrastructure cannot be reproduced consistently • a startup needs someone who understands both infrastructure and application engineering • Linux/networking problems cross the boundary between application and infrastructure • an existing product needs cleaner deployment, recovery, security, or operational documentation I value clean infrastructure, explicit ownership, secure defaults, reproducible environments, and documentation that the next engineer can actually use. If your infrastructure or deployment process has become difficult to operate, send me the current architecture and the problem you are trying to solve.
