Marcos Daniel Alvear BarrigaFull Stack Developer
I'm a Fullstack developer with over 7 years of experience. I like to find solutions to problems. I analyze a situation and synthesize an explained overview with ease, which can then be used as a guide for development for myself or my team. I have plenty experience. On the frontend with Angular 9 and 10, JavaScript, jQuery and all common libraries. On the backend, I have worked on PHP, C#, Java. Object Oriented or just functional programming. MVC. At a database level, I have worked with all major SQL engines, such as T-SQL Microsoft SQL Server, Oracle, MySQL, PostgreSQL. Queries, views, stored procedures, jobs, and I also have done Stripe and other payment implementations.

Full Stack DeveloperDTIWare Technology
12/2022 - Currently

I'm a freelance full-stack developer in DTIWare. They have multiple cloud-based technologies, and I'm currently working on two of them: ERPs and E-commerce. I give maintenance to the ERPs, updating the database structure and applying set-based design to better the time response on reports and the whole ERP in general. I'm also currently in charge of the implementation of the new Human Resources module and of updating the front-end look and feel. And for e-commerce, I'm in charge of implementing full-stack changes based on the requests made by the client.
