Back to original languageAbout Jc
Ever since I got my first computer at 14 (an MSX with a BASIC environment), I knew I wanted to dedicate myself to this profession. Today, I am incredibly fortunate to do something I love and am good at. Programmer, analyst, and recently, I've been particularly interested in process architecture and work methodologies (with several online courses in Scrum). Extensive experience in programming with .Net (VB and C#), Windows Forms, Xamarin, WPF, ASP .Net for REST services, and web applications with Blazor. In terms of databases, I've worked with Access but more recently with MySQL, MariaDB, and SQLServer. Crystal Reports for reports and printing. Basic level in PHP, HTML5, CSS3, JavaScript, and PERL.
Always trying to stay updated with professional developments, as much as possible, in constant learning and innovation.
My motto is: "Dedicating efforts in development minimizes efforts in maintenance".
In addition to my experience and knowledge, I have a team of trusted individuals to turn to for any obstacles, always ensuring the best customer service.

- BinTech SolutionsGateway developmentSOFTWARE PUBLISHINGOctober 2010 - Today (15 years and 9 months)Aranda de Duero, SpainA client had Excel spreadsheets (version 2000) that connected via SOAP to an HMI device for data dumping. When the Office package was renewed, the SOAP libraries became obsolete and stopped communicating. The initial idea was to update the macros, but ultimately, an independent solution was proposed: a gateway developed in VB.Net responsible for communicating with the device and dynamically updating Excel sheets, both old and new, using templates. This gave the system the ability to incorporate different ways of exploiting the data without changing the dumping system.
