Current job at CIID S.E.

Since 09/2022 I work in a state company called CIID S.E. (https://www.ciidse.ar/) , which belongs to the provincial government of Santiago del Estero – Argentina.

I work as Systems Manager, being in charge of software projects related to generate interoperability in the different public departments of the state and private entities.

I have a team in charge that I have to manage, monitor, mentor, and watch over their work and professional growth.

Having projects related to the State/Government, I could say that the projects in which I work have a considerable political interest, since the projects consist fundamentally in systematizing bureaucratic processes of the government through the use of technology and software.

Although I am not in a full-time software developer position, I always organize the time and space necessary to be able to program mission-critical software on the projects we take on with the team.

Previous job in Tradebyte GmbH - Germany

From 03/2019 until 08/2022 I worked as a senior PHP developer at Tradebyte GmbH (Zalando), located in Germany.

I worked at the core of the product, created in pure plain PHP, some of things we did were for example:

• SQL queries optimization
• Integration with external services like Amazon S3 and SES
• Code and framework develop and refactor
• Code optimization
• Managed to migrate from PHP 5 to PHP 7, and initiated the process to migrate to PHP 8.
• All code was done with TDD and BDD
• etc.

Was also part of my daily tasks to:

• Do code reviews of the work done my colleges
• On board new team members
• Participated in projects (what I mean is didn’t do just development, but I was also involve in the decisions about what to do and how)

I do have a recommendation letter from the company, describing my participation there with more details. Reference letter

• Contributed with the json_validate() function released in PHP 8.3
• QA contributions, enhancing and writing new tests to increase the code coverage of the project
• 22 Pull requests in total
• Participate in the “Internals Email List”
