Hello, this is Sergio, an italian software engineer with more than 20 years of experience in IT software development. In my last work I built from scratch the entire software platform of SoundsOfThings, consisting in Backend API, Mobile app for Android and iOS, two web sites for business partners. I designed the software architecture, selected the technologies to be used through the entire stack and wrote the code of the mobile app plus part of the Backend API, while coordinating the other team members using SCRUM on Jira and Confluence (for reference you can find the app on the apple / google store searching for "soundsofthings", you can download and install it to have a look at the work done). Quality, punctuality and reliability are the pillars of my work. I use best-in-class approaches to software projects like TDD and SCRUM. Also I select best software components to work with, as Loopback, Ionic, MongoDB, AWS, etc. I prefer to code using Typescript over Javascript because it is a more reliable language. I'm available for both fixed and hourly projects, let's have a talk on your needs.
