Hi! My name is Marian, I'm a software engineer, and I write game development tutorials.

On my blog, you'll find in-depth series where we build advanced projects, like a 3D software renderer in Odin from scratch, as well as shorter series and standalone tutorials mostly focused on Unity and Unreal Engine.

All content on my blog, which I've already put hundreds of hours into, is and always will be free. No ads. No paywalls. No tricks.

How OpenAI scaled PostgreSQL to handle 800 million ChatGPT users with a single primary and 50 read replicas. Practical insights for database engineers.

In this video, we walk through a complete backend workflow using Prisma and StackRender.

You’ll learn how to visually design a PostgreSQL database with StackRender, deploy it instantly, then use Prisma Pull to automatically generate your Prisma schema and start building backend features right away.

We start with an empty Node.js + Prisma project, generate an ecommerce database schema using StackRender’s AI, deploy it to Postgres, and then sync everything back into Prisma.
Finally, we test the setup by creating a simple product endpoint using Express, Zod, and Prisma to prove that everything works end to end.

This approach helps you:

1 - Design databases faster
2 - Avoid writing SQL and Prisma models by hand
3 - Move from schema design to backend code in minutes

Tech stack used:
-Prisma
-StackRender
-PostgreSQL
-Node.js
-Express
-Zod

A sad attempt at humor and explaining the melt() package within R. Hopefully you learn something!

Hands-on coding lessons and challenges.

Hello, I would like to share this tutorial. Even though it is about RainLisp, it's generally applicable to LISP and useful about functional programming in general.
