I started working professionally as a web developer in 2006. From 2007 to 2021 I worked in a company that provides telephone, internet, and television services. There, I participated in developing several software projects in teams of 2 to 5 people, although in most projects I worked as a full-stack developer in projects, as a single programmer, in constant communication with the project manager. Since 2015 I have worked using the Scrum methodology and as a company policy, I used TFS for task tracking and updating the product backlog items selected for each sprint. I have also used Git for source code versioning. I have used DDD and Onion Pattern in projects developed in .Net My preferred languages are C#, PHP, and Java, although I have experience in others. Also, I am experienced with frameworks like .net, Entity Framework, angular, and the following DBMS: MySQL, Microsoft SQL Server, PostgreSQL, and MongoDB
