WISP is an acronym of **Whisper from the past**. A discomfort that lingered, a memory that suddenly came back, an idea too good to let slip — hotkkangs, an AI engineer and developer, turns these small voices from moments gone by into services and runs them personally, after work and on weekends.

A note left at a place is a memory that opens only when you go back there. The voice from a past call should be one only you can hear again. Looking back, many of WISP's services deal with **signals the past sends to the present** — AstroShare, a community for astrophotography; PigNote, which lets you bury memories in places; and voice-lock, which protects past calls. This is where I listen to those small whispers and build them alone, end to end, from planning to deployment and operations. 10 Projects built Solo From planning to deployment GCP Self-deployed and operated AI Working as an AI engineer ![WISP logo — a whisper from the past](https://www.j2w2.org/images/brand/wisp-company.jpg) *WISP — Whisper from the past* What I've built so far ## Projects Ten projects I run myself, each one a whisper from the past turned into a service.
