🌐 Portfolio: khainam23.vercel.app
I run production infrastructure. My focus is reliable CI/CD, observable systems, and fast incident response.
- 🏢 DevOps Engineer @ Nexsoft Technology: I operate ~76 production servers running Docker-based microservices and blockchain full nodes across Dev / QA / Prod.
- 🎮 Lead DevOps @ Zero to Hero: I keep the servers of a live pixel MMORPG (PC + Android) healthy and handle production issues.
- 🔁 I build Jenkins and GitHub Actions pipelines, and monitor with Prometheus, Grafana, Loki, Beszel and Uptime Kuma.
- 📈 I load-tested a platform with Docker Swarm, validated at 12,000 concurrent users across 3 servers.
- 🤖 I build AI agents with the Claude API + MCP to triage bug reports and auto-resolve simple incidents.
- 📄 Co-author of 2 Q1 papers on route optimization: Applied Soft Computing (2025) and IEEE Access (2026).
- 🎓 B.Eng. in Information Technology, Nong Lam University HCMC (GPA 3.5/4.0).
