You're not a senior engineer until you've worked on a legacy project (2023) (infobip.com)
Everybody hates working on legacy projects, myself included. As fate would have it, one landed in my lap recently. While working on it didn’t make me hate legacy projects any less, it did help me get a deeper understanding of the processes and practices we use today.

It’s been a long while since I wrote anything on this site. The framework I used was Gatsby which in 2020 was one of the hot ways of getting a good looking blog up and running quickly. With over 41 dependencies, and god knows how many more sub-dependencies, this thing was a beast.

Ask HN: Junior dev in charge of rewriting 500k line PHP app. Looking for advice (ycombinator.com)
We are a 4 person company, that makes a web app I'll call Star. Today, Star is 11 years old and showing its age. It was developed entirely by one of the founders, who has no formal training, and the niche industry we serve has changed greatly in the last decade, rendering many of our core abstractions obsolete. In theory, Star follows MVC, but in practice there is no coherent architecture.
