Dear possible client,
After greeting you, I would like to express my interest in this job. I am a self-taught programmer with a lot of passion for web development and Software Development in general.
I really like the idea of creating a custom and awesome loading page for a website because it tells the user that wat he's about to see is professional.
I can make both the design and the code implementation using JavaScript (it doesn't matter if you need React or typescript or just vanilla js) and SVG (vector graphics animation).
Hope to hear from you soon.
Regards!
