My Story

I’m currently working as a Bioinformatician and Web Developer at BROWSer, a University spin-off company that I co-founded, while doing my PhD in Bioinformatics.

You can check my complete story and download my resume from my curriculum page.

If you need a great website for either yourself or your company, good news for you, I’m currently available for hiring, also from remote. Drop me a line to explain your needs and we’ll arrange something together!


For freelancers and business websites, my usual choice is WordPress, given its broad capabilities and customization options. I use a wide range of both free and premium themes, based on the design and functionality requested.


I usually employ the Python programming language together with a web framework like Flask for websites needing custom database integration and advanced functions. Mostly this regards biological databases, but the choice is endless.


These are the foundations of Web Development, and can be used for any task, from creating a complete website to developing specific snippets to be integrated in an existing platform. I usually employ this for landing pages.
