Development write-ups from real projects

Expona Blog is where the engineers behind Expona share what we learn building and running real systems. Every article starts from a problem we met in production — an API that had to scale, a deployment that broke, a design decision we had to defend — and explains what worked, what did not, and why.

What you will find here

• 100-day series — one focused article a day on a single stack, from first setup to production: .NET, NestJS, React, AWS, Kafka, Flutter, AI and more. Browse the series.
• Categories for backend, frontend, mobile, cloud and DevOps, data, AI and machine learning, architecture, security, testing, and career. See all topics.
• Code you can copy, diagrams you can reuse, and the trade-offs behind each choice — not just the happy path.

How articles are made

Articles are written by practising engineers and reviewed by an editor before they are published. We keep them up to date when tools change, and we correct mistakes openly — if you spot one, tell us.
