We have collaborated with Luis in numerous projects of diverse complexity within the airport and aeronautical sectors. He has always integrated in our team with great professionalism and a positive mentality, adapting to the circumstances and giving the maximum to obtain the best results.

Software Point contracted Luis for many years in different LIMS projects. We are impressed by the professionalism shown by him and we have learned to trust him as a reliable partner who produces the results on time and at the agreed cost.

I sincerely recommend using the services of Luis. He is friendly, professional and reliable to work with. He is very flexible in the organization of projects, have an enormous experience of work in important projects and his capacities in programming are excellent.

Luis was responsible for developing and maintaining an important part of the software that we use on a daily basis for the control of samples and analysis in our laboratory. Part of the software is used with our final customers, who enjoy an application for the generation and sending of bar codes with their samples. This has allowed us a leap in quality in terms of the service we offer.

A little bit of my story as a developer

Started using React in 2017 with a background of JavaScript, jQuery, HTML, CSS and AngularJS. Now I love React and have created many complex applications with react-router, Redux, Sagas, Observables, Hooks, React Query, tRPC, Prisma, NextAuth and many other libraries/APIs.

Regarding styles, I have worked with CSS-in-JS solutions, mostly Styled Components, and with design systems like Mantine and MaterialUI. I enjoy creating reusable components and providing a pixel-perfect UI. I enjoy working with designers and UX experts using Figma, InVision and similar tools.

Regarding the backend, I have long experience with REST APIs, JSON, C# and .NET technologies: ASP.NET MVC/WebAPI, Entity Framework, Linq, SQL Server. Most of my career I have worked with SQL databases, but I have experience with a NoSQL database as well (DynamoDb).

Used to Agile methodologies, CI/CD (Jenkins, Bitbucket pipelines, GitLab) and testing: Jest and react-testing-library for unit and component tests, Cypress for end2end tests.

Highly self-driven but at the same time enjoy being part of a team and get involved in all parts of the product development. Used to working in international, multidisciplinary development teams, willing to give and receive feedback to and from my teammates in code reviews and direct conversations. Not only focused on robust architecture and clean code, but also think a great user experience is crucial.

Lately I am working with NextJS, Server Side Rendering, NodeJS, NextAuth, tRPC, Prisma and type-safety from the backend to the frontend, which I find very exciting and promising.
