About

WISP is Whisper from the past — a whisper from the past. It is the name for the personal projects in which hotkkangs, an AI engineer and developer, turns the small voices of moments gone by into services as a hobby.

Whisper from the past

WISP is an acronym of Whisper from the past. Good ideas rarely arrive with fanfare; they usually come as a small voice — a discomfort you once had, or a memory you held on to for a long time. Just as the English word wisp means 'a thin streak of smoke, a faint trace,' WISP is about catching what remains faintly instead of letting it drift away, and turning it into a service. Rather than a grand company, it is the name for the projects that hotkkangs, an AI engineer and developer, builds as a hobby and runs personally, from deployment to operations.

Focus

What I'm into these days

01
From planning to deployment, myself
I handle planning, development, deployment, and incident response on my own, building hands-on experience.
02
Web and apps
I try out React, Vue, and Next.js, and also build Flutter and native Kotlin apps, gaining experience across the board.
03
Working as an AI engineer
Drawing on my experience as an AI engineer, I'm building AI agents that are actually useful, one at a time.
04
Deploying it myself
I deploy and operate on GCP myself, building real know-how in running services.

AI Engineer / Java · Node.js Developer

An AI engineer and a developer working with Java and Node.js. Day to day I mostly work on backends and AI agent development, but when something makes me curious I like to get my hands on the frontend and the infrastructure too. I build and run projects like OG, Dokak, Postit, and AstroShare as a hobby.

How I build

bolt

Just build it

Rather than waiting for a perfect plan, I like to build first and fix things as I use them.

See it through

I take sole responsibility for planning, development, and deployment, and look after the whole flow myself.

Applying new technology

I apply what I've learned working as an AI engineer to the services I build as a hobby.
