Hello everyone! My name is Artyom Peskishev, I am an iOS developer in Avito. I want to tell you how we started a backend-driven script for publishing new ads in our mobile applications.
Let’s see what step-by-step scripts are in applications and what problems we had with the script for placing an ad. The article is about a tool we developed to solve these problems and the results of its implementation.
