Sudoku is a game where your goal is to fill all the 9x9 grid where each row, column and subgrid of 3x3 must contain numbers from 1 to 9 only once. Algorithm that solves these problems are really fun and they can go much more complex than you think.

The two repositories I contributed to aren’t very popular: aedes-cli gets around 1,000 weekly downloads, and mqemitter-redis about 7,500. Still, I consider this a solid starting point for anyone looking to get involved in the open-source community.

Moonenv is my CLI application for managing environment variables, which I discussed more about in this article. This solution had been running for a few months, and I was able to validate my idea, but a crucial part was still missing: authentication!!!

So, for a few weeks, I entered a research and development phase using GoLang and Rust, which I will discuss in this article.

Currently, the backend applications I write are built using NodeJS with the NestJS framework, MySQL as the database, and Prisma as the ORM. This stack is excellent for quickly building MVPs. However at the beginning of the year, some of our projects completed the previous year began exhibiting strange behavior and over time the servers became unavailable.

Learning Rust for me was like revisiting my two years of experience programming embedded systems in C. There are still many concepts I don't fully understand, but that doesn't worry me because I pick them up as I work on my personal projects in Rust.

I chose a CLI project to start this journey because I felt the challenges I would face along the way would be interesting—and they were!
