About Jiajun

Jiajun Liang

I design repeatable systems that compound across software, capital allocation, slow travel, and inner work.

Former QA engineer translating reliability instincts into product, infra, and research workflows.
Building market models that blend automation, narrative tracking, and long-form writing.
Slow-traveling out of Vancouver and capturing routines that make each city feel like home.

What I’m exploring right now

Systems & code

Leveling up containerization, observability, and end-to-end testing with Docker, Kubernetes, and Playwright.
Turning QA rigor into tooling that shortens feedback loops for small teams.

Markets & energy

Mapping AI datacenter power builds and the capital stack behind them.
Stress-testing theses with scenario planning, risk limits, and journaled reviews.

Travel & learning

Designing travel operating systems that protect deep work while moving between cities.
Noting how meditation and breathwork influence focus, decision speed, and writing cadence.

Why this garden exists

To publish working notes on how engineering discipline, market structure, and travel habits reinforce each other—and to invite conversations with people navigating similar intersections.

Now

Location: Vancouver, BC
Active projects: Digital garden overhaul, automation of market memos, and sourcing power-grid data.
Practices: Daily writing sprints, interval training, and Vipassana sits.
