POC-Driven Learning: Build Small, Learn Fast
July 1, 2026 ·learningengineeringpoc
The fastest way I’ve found to learn a new technology isn’t a course or a book — it’s building a deliberately tiny proof-of-concept.
The rules I follow
- Timebox it. One evening or one weekend. If it needs more, the scope is wrong.
- One question per POC. “Can I stream LLM output through a Lambda?” — not “build an AI app.”
- Ship something visible. A repo with a README, a demo GIF, or a post here. If it isn’t written down, the learning evaporates.
- Throw the code away guilt-free. The artifact is the understanding, not the code.
Why it works
Tutorials optimize for following along. POCs optimize for getting stuck — and getting stuck is where learning happens. When the happy path breaks, you’re forced to read the docs, the source, the error messages. That friction is the point.
The compounding effect
Each POC becomes a card on my projects page. After a year, that’s dozens of proofs that I can pick up anything quickly — which is arguably the most valuable skill signal there is.
