Open to connect & collaborate

Hi, I'm Kelvin.Tech tinkerer. Homelab nerd. Runner.

Welcome to kelptan.work — a space where I share my curiosity about technology, from spinning up homelabs and exploring networking stacks, to dabbling in SaaS and new tools. When I'm not at a terminal, I'm out on the pavement — running keeps the mind sharp and the spirit grounded.

Networking

VLANs, firewalls, DNS, and everything that keeps packets moving. I love understanding how things talk to each other.

🖥️

Homelab

Self-hosted services, Proxmox VMs, containers — my homelab is my playground for breaking and learning things.

☁️

SaaS & Tools

Exploring new software, productivity stacks, and cloud services. Always on the lookout for a better workflow.

🏃

Running

My daily reset. A good run clears the mind, builds discipline, and makes the tech problems feel smaller.

🌱

Curious by Nature

Always poking at something new — a gadget, a concept, or a person. I love good conversations and unexpected friendships.

🐱

Cat Person

Proud cat lover. There's something about their independent, curious nature that I deeply relate to.

Community & Giving Back

Whether it's sharing knowledge, lending a hand, or showing up — I believe in contributing to the community in whatever ways I can.

I'm Kelvin Tan, a technology enthusiast based in Singapore. I'm not a professional programmer, but I have a deep love for understanding systems — how networks talk, how servers hum, and how the right tools can make life simpler. This site is my corner of the internet to share what I learn, build, and explore.
