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

I started working with React in 2017, building on a background in JavaScript, jQuery, HTML, CSS, and AngularJS. Since then, I have developed numerous complex applications using technologies such as React Router, Redux, Redux Saga, RxJS, Hooks, React Query, tRPC, Prisma, NextAuth, and many other libraries and APIs.

On the frontend side, I have worked extensively with CSS-in-JS solutions, primarily Styled Components, as well as design systems such as Mantine and Material UI. I enjoy creating reusable components, delivering pixel-perfect user interfaces, and collaborating closely with designers and UX specialists using tools like Figma, InVision, and similar platforms.

On the backend, I have extensive experience with REST APIs, JSON, C#, and .NET technologies, including ASP.NET MVC, ASP.NET Web API, Entity Framework, LINQ, and SQL Server. Most of my career has involved working with SQL databases, although I also have experience with NoSQL solutions such as DynamoDB.

I am comfortable working within Agile environments and have hands-on experience with CI/CD pipelines using Jenkins, Bitbucket Pipelines, and GitLab. Testing has always been an important part of my workflow, using Jest and React Testing Library for unit and component testing, and Cypress for end-to-end testing.

I am highly self-motivated while also thriving in collaborative environments. I actively contribute throughout the entire product development lifecycle and have extensive experience working with international, multidisciplinary teams. I value open communication and continuous improvement, both through code reviews and direct collaboration with colleagues.

Beyond building robust architectures and writing clean, maintainable code, I place a strong emphasis on delivering excellent user experiences. In my view, technical quality and user experience are equally important to a successful product.

More recently, I have been working extensively with Next.js, Server-Side Rendering (SSR), Node.js, NextAuth, tRPC, and Prisma, embracing end-to-end type safety across the entire stack—an approach I find both powerful and highly promising.

After many years focused on professional software development, I launched my first personal project: dividendo.top. It is a tool that helps investors track their portfolios and dividend income, monitor both paid and upcoming dividends, and manage important dividend-investing considerations such as withholding taxes, foreign tax credits, and income tax reporting.
