The impact on the customer experience during social isolation.

Written by Rodrigo Passeira — Head of solutions at Sinch

The pandemic has impacted our personal and professional lives, social isolation has brought about changes in habits and impediments that we could not imagine we would live. Who would bet at the end of 2019 that this would all happen? We are living in a time of change that is accelerating digitalization in many companies and, due to the isolation, all of them had to face changes in rules, some of which had variations in sales volume upwards, because they have…

My story at Wavy (now Sinch) started in January 2020. I already started the year with great news, as I always had the dream of working in a large company like this, where I would be challenged every day, learning and delivering new things.

More and more we have more complex web applications with several streams and with a more refined layout. The screens have been designed to serve the user an explosion of colors, interactions, animations, textures, sensations, whew! You should imagine the work it takes to do and maintain all of this, especially with teams that are growing and becoming multispecialized, having several roles such as Frontend, Backend, Devops, Designers, among other roles.

One thing is a fact, maintaining all of this code is complicated, even when we have unit tests, but what about the visual? …

How did continuous integration come about?

In 1935, Austrian physicist Erwin Schrödinger proposed a mental experiment in which a cat is confined to a cardboard box with a glass of poison and a random trigger that can release this poison.

So, according to Schrödinger, we must consider him alive and dead. …

Who never had problems with thread starvation, who never went wrong by blocking the main thread or who never got lost in the famous Callback Hell?

Asynchronous programming is one of the big issues of the moment and is gaining more and more importance, both in the area of ​​Back-End and Front-End.

We still use Java a lot here at Movile and we believe that the language competition solution is difficult to use (and we are not even commenting on the debugging part of it all).

In addition, Java does not encourage reactive programming, let alone non-blocking IO. We have…

Perhaps the following situation has already happened to you: when you access a page to fill out a form, you end up giving up on completing it until the end. Filling out several fields on a single web form is a bit tedious, but worse than suffering from boredom, you lack patience when trying to load a field like the list of cities or neighborhoods.
