Cracking the Code: Understanding Demand in Your Job Market and Boosting Your Career

I don't spend money on things I don't need. Nobody does — at least not intentionally. We buy things because they solve a problem we have right now.

That's demand. And understanding it is the single most important thing for your career.

The vending machine test

Imagine you're on a mountain trail in Japan. You're dehydrated. There's one vending machine. The water costs three times the normal price. You pay it without thinking. There's no alternative. The demand is absolute.

Now put that same vending machine in a park with a free water fountain ten meters away. Nobody's buying.

The product didn't change. The demand did.

Apply this to your career

Your skills are the product. The job market is the location. If you're offering something that's abundant and easily available, your value drops — no matter how good you are at it.

But if you're offering something scarce in a market that desperately needs it, you can name your terms.

How I think about it

Every few years, I audit my skills against the market. Where is demand growing? Where is supply flooding in? What can I do that most people at my level can't?

Early in my career, knowing React was a differentiator. Now it's table stakes. The differentiator shifted to system design, team leadership, cross-functional communication — things that take years to build and can't be learned from a weekend tutorial.

The uncomfortable truth

Technical skills are necessary but not sufficient. The engineers I see commanding the best opportunities aren't just good coders. They're the ones who understand the business, can talk to stakeholders, and solve problems that span organizational boundaries.

Position yourself where demand is high and supply is low. That's not gaming the system. That's understanding how the market works and aligning your growth accordingly.
