I'm Zixian. Apptitude is my personal collection of situations, mental models, and notes on software in Govt. Written for people who make decisions about tech.
The Knowledge Base
How things actually work
A reference library of technical concepts, stripped of jargon and explained with plain English and clear diagrams.
The Playbook
Thinking through decisions
Opinionated frameworks for product strategy, scoping, and stakeholder management. This is how I approach the work.
For everyone who's ever nodded along pretending to understand the tech stuff.
