ValQuaCom was a company that developed applications for various companies, the most prominent of which was Entrepidus, a global service provider of solutions that collect source marketing and consumer information.They (Entrepidus) required to migrate their main solution (ISSY) from Android Native to Xamarin Android and I led the development of this new version of ISSY.My main contributions to this project:- I made excellent technical decisions for the project, including the choice of Xamarin Android over Xamarin Forms.- I designed a loosely coupled architecture to separate concerns between layers.- I implemented the MVVM software architectural pattern.- I implemented MvvmCross, which is a convention based MVVM framework for Xamarin.- I developed the model layer, the business layer and the presentation layer, including activities, fragments, layouts and other native Android components.- I created the abstractions and implementations of most of the required services.- I applied SOLID principles and design patterns to make the software designs more understandable, flexible and maintainable.- Most of the code I wrote was clean.- I wrote all the asynchronous code correctly.

Excelsior Gama Supermercados is one of the largest supermarket chains in Venezuela.I developed all the layers of a mobile application that still facilitates the management of products that require special configurations due to government laws. The stack used was Android, ASP.NET Web API 2 and Microsoft SQL Server 2012.Frequently the business needed to have in relational databases data of its SAP implementation, therefore I created integration components that periodically and automatically import data from SAP to Microsoft SQL Server databases. For the creation of these components I used SAP XI/PI.My greatest achievement in this work and my biggest contribution to this company was to successfully lead the development of the point of sale when this development was stopped because the company could not continue counting on the only person who had knowledge about this system. It was a big challenge because there was no technical documentation about the system and because I had no experience in desktop applications with the .NET platform. The versions that I developed were deployed in more than 250 computers of this supermarket chain and these changes increased the security of the system, improved the purchase times and never presented errors.
