Good day. I am developing on Angular/Nest.js and have experience with analytics services. I developed a system similar to Google Analytics but for managing hotels. I have over 5 years of experience with Nest.js, feel free to contact me to discuss the details. To evaluate the project, it needs to be seen.

I knew that a degree in cybersecurity would be useful for me, haha. It's true, not about security, but I hope you don't have anything too secure. I also have a lot of experience with bare, I can send my Git in a private message.
