About this blog

This is the engineering blog of CST Solution, a small studio that builds and runs apps, games and developer tools.

Every article starts from a question we hit while building something — why a request took eight seconds, whether a Bloom filter's 1% is really 1%, which schema change locks a table — and answers it with a measurement rather than an opinion. Where it can, each article ends with something you can run yourself in under a minute.

What you will find here

• Infrastructure — servers, containers, databases and proxies.
• Integration — webhooks, APIs, retries and scheduling.
• AI & Data — extraction, search and text processing.
• Games — pathfinding, procedural generation, netcode and animation.

Who writes it

The blog is written by Chi, owner at CST Solutions, who runs the studio behind the products mentioned here.
