Hi, I'm sunl19ht 👋

Backend Developer · Linux · DevOps · AI Infrastructure

Building software. Managing infrastructure. Exploring AI systems.


🧑‍💻 About Me

I'm a Software Technology student focused on backend development,
Linux infrastructure, DevOps automation, and AI infrastructure.

I enjoy building systems from the application layer
all the way down to the infrastructure underneath it.
  • 🎓 Software Technology student
  • ☕ Mainly focused on Java / Spring Boot
  • 🐧 Linux & infrastructure enthusiast
  • 🐳 Docker / Podman / Kubernetes
  • ⚙️ Jenkins / GitLab / Ansible
  • 📊 Prometheus / Grafana
  • 🌐 Networking / DNS / Nginx / Proxmox
  • 🤖 LLM inference & AI infrastructure
  • ⚡ Currently exploring NVIDIA DGX Spark / GB10 / vLLM
  • 🔧 I enjoy debugging things that should work but don't

Build it → Deploy it → Break it → Debug it → Automate it


🚀 What I'm Working On

🤖 AI Infrastructure

Currently exploring LLM inference on NVIDIA hardware.

Current interests:

LLM Serving · vLLM · DeepSeek · CUDA · GPU Infrastructure · Distributed Inference


🏗️ My Tech Landscape

Backend

Java · Spring Boot · MyBatis · MySQL · Redis · JWT


Frontend

Vue · JavaScript · TypeScript · Element UI · Vite


DevOps

Docker · Podman · Kubernetes · Ansible · Jenkins · GitLab CI/CD · Nginx


Linux & Infrastructure

Ubuntu · Debian · Rocky Linux · Bash · NetworkManager · Proxmox

Also working with:

FreeIPA · LDAP · Kerberos · Chrony · DNS · NTP · VLAN · Reverse Proxy


Monitoring

Prometheus · Grafana · Node Exporter · Podman Exporter

I like knowing what the system is doing, not just whether the application is running.
