Highly scalable applications, open-source frameworks, and libraries, Sentry all the way – welcome to the back-end life. Here at Tesonet, our infrastructure is based on microservices and REST. Our SLA is to be upheld and we strive to write beautiful code as much as we can. We can’t imagine our work without RabbitMQ allowing us to execute the code of our applications asynchronously. And when it comes to databases, we trust in SQL and NoSQL to make our lives easier. Every challenge that comes our way, we smash together, unifying our logical, computing, and creative skills. Even if it’s something crazy, like building a boat powered by an electric skateboard.
