Who's Behind This

Nensi Ahmetbeja

Software engineer from Albania. I've built banking systems at Raiffeisen, fintech products at AiLend, and co-founded Kungul App. Chevening Scholar at UCL London.

nensplain is how I explain the systems I work with, software architecture, AI infrastructure, startup mechanics, the way I'd explain them to a smart friend over coffee.

What Gets Explained

Three areas. One method.

⌨

Software Systems

How Git works under the hood. Why 99.9% uptime still means 9 hours down. What actually happens when you type a URL. The mechanics behind the tools you use every day.

⚙

AI & Infrastructure

Why inference costs matter more than model size. How MCP connects AI to your actual tools. What hallucinations reveal about how models work. The real architecture, not the hype.

▲

Startups & Strategy

How venture capital actually flows. Why most startups die from distribution, not product. What product-market fit feels like vs what it sounds like. Systems behind the business.

The Method

What you get with nensplain

1
▦

The Framework First

Every topic starts with structure. Before facts, before examples, you get the mental model. The skeleton that makes everything else click.

2
⚙

The Real Mechanics

Then we go under the hood. Not what a thing is called. How it actually works. Why it was built that way. What breaks when it fails.

3
✶

The Analogy That Sticks

One concrete example. A comparison you already understand. Something that turns abstract into obvious, so you remember it tomorrow, not just right now.

4
➤

The Bigger Picture

Where does this fit? How does it connect to the next thing? You leave with a framework that applies beyond this one topic, not just an answer, but a way of thinking.
