Hi, I'm Jesus Enrique and I love building software

WPF Invoice System Windows App

I came up with this idea while working in my family business. They had stopped using the previous invoice system of the company because it had many bugs and the license was expensive. In addition, I had always been interested in building a Windows desktop application, and I knew C#, so I decided to make a new invoice system for the company. The development was a challenge for my Object Oriented Programming skills, and I even had the opportunity to put into practice some design patterns. The project in this portfolio is a lightweight version of that project because the latter has more company-related features that I decided not to include here.

I choose WPF for the windows client app development instead of newer frameworks such as MAUI, primarily because of the old hardware that we have in the company. I also used the Prism library for an easier way of handling navigation.

Now about persistence: I went with SQL Server in the original project, but for this one I used SQLite so that it is easier to offer to the users testing this porfolio app, an option to clear the date they inserted. It's also important to note that, in both cases, I managed the DB through Entity Framework code-first approach.

Acompañar+ (No Country Simulation MVP)

I participated in a 5-week work simulation as a Backend Developer within a diverse team of talented developers and UI/UX designers. There, we built a MVP called Acompañar+ with React and Express.js. The project aims to create a bridge between the elderly and the new generations through community activities.

This was such a rewarding experience because I had the opportunity to improve several of my soft skills such as teamwork, problem-solving and also my ability to communicate complex technical concepts across different disciplines. Also, since we had a compressed timeframe, I gained valuable experience in prioritizing tasks and adapting to changing project requirements.

Bookmarks keeper

This was a personal side project. I got the idea from the Saved Messages telegram feature, whose interface is technically a chat. I used to use that chat to save some of my links, but I wanted a way to group them by category. That's why I decided to build my own bookmark keeper app (For the record, It was after I finished the app that I found out about Pocket).

I used the MERN stack dividing the project into API and client. For the backend, I used the link-preview-js npm library by Oscar Franco to present the site information and Passport JS with JWT for authentication and authorization. As for the client UI design, it uses Material UI and its card component to make the bookmarks similar to the link previews you can find on chat apps. Recently I migrated these projects, and now Typescript is utilized on both.
