Press & data
For journalists: the data, the method, and a bio you can quote.
The job-posting numbers behind the posts come from employers' own public hiring boards, not from job boards. Here is how they are collected, what they cannot show, and how to reach me.

Bio
Short, first person
I write Rust and Android code for two kinds of people: job seekers tired of ghost postings, and people whose phone might be taken away.
Third person
Alan Wisper is a software engineer in the United States working in Rust, Android and security. Current work: a browser extension and a daily crawl of employers' public hiring boards that show a job posting's real age, and a Rust storage library for Android, built to survive a phone seizure, with machine-checked proofs in Verus.

How the numbers are made
Data and method
- Source: the public, unauthenticated job-board endpoints of Greenhouse, Lever and Ashby, the systems behind the “Apply” button at most tech companies. No job board (LinkedIn, Indeed, Glassdoor) is crawled.
-
Age is measured from the employer's first-published date:
first_published(Greenhouse),createdAt(Lever),publishedAt(Ashby). - What the data cannot show: why a posting stays open, and whether a closed posting was filled or withdrawn. Every post says this again in its limitations section.
