Hi, I am

Luis Serrano

I am a Software Engineer.

about me

Who am I?

I am a Software Developer, and I have been coding for more than 20 years. I have used many technologies, but my strongest skill is Javascript development. I specially like React/Redux. I am normally in charge of making things look pretty (front-end, UI/UX). My approach is simple: I don’t seek to reinvent the wheel, nor impress you with over-engineering.

I learn fast and I love new frameworks/libraries, but I am not a follower of trends for the sake of hypes. I don’t require much, but I expect fair play and transparency.

I love new challenges and I believe I have done some interesting projects over the years, some of them I am really proud of. I am always keen to learn new things from the best out there.

Finally, I love mentoring junior developers, teaching them soft/hard skills to help them in their careers.

That’s me.

Izabela Wlodarska

Sitecore Developer/Consultant (Contractor)

I worked with Luis for five months on a large Sitecore SXA build. He is a very competent frontend developer that is not afraid to learn new skills and experiment with new technologies to push his work and get the best result for the clients. Because of his extensive experience in software development, he became quickly the key frontend developer in our team. He was able to master the new technologies very quickly and set high-quality standards and patterns to follow for the other members of the team. Despite the time pressure, he is able to deliver the expected tasks while maintaining a high quality of the code. I totally recommend Luis for any frontend developer/lead role.

Maarten Dalmijn

Product Owner / Bynder

I loved working with Luis. He brings a positive attitude with a healthy dose of humor to his work, no matter how tough the situation. Luis knows how to do hard technical work but he is also able to explain technically challenging subjects to less technical people like myself. Very often after talking to him all that was not clear suddenly became very clear. This was extremely valuable to me and helped to move things forward significantly. Luis is very T-shaped which helps to bring down potential silos in a company and look beyond just his own job.
