Development of web applications using modern tools with angular, react, vue and svelt in the front end. Better formatting of interfaces with Sass, Less and Stylus, css3. Development of API's and microservices with Nodejs, Nest, Koa, Express, Mongodb, Postgres, graphql, JWT among others. Despite the alphabet soup above, application development needs to target the results that the "customer / partner" wants to achieve. I am totally adherent to this methodology.
