A book by Jermaine Barker
The Laboratory
Method.
How Scientists Build Bulletproof Careers in Tech.
Credentials open conversations. Skills close the deal. A trained scientist who became a technologist shows you how to run your career the way a lab runs an experiment: form the hypothesis, run the sprint, measure, iterate.
What the method is
Four ideas that change how you make career decisions
Careers are experiments, not ladders
Every move is a hypothesis with a measurable result. You stop guessing and start running tests.
The 90-day sprint
Long enough to prove something real, short enough to change course before the cost gets high.
Velocity is not progress
The four-quadrant check that tells you whether you are actually moving or just busy.
Authority through reproducible results
How documented, repeatable wins compound into the reputation that opens doors credentials cannot.
