About me
My name is Francisco Gonçalves. I’m a 26 software engineer based in Porto. I hold a Master’s degree in Computer Science and Engineering from FEUP (Faculty of Engineering at the University of Porto).
I enjoy all things software, with a strong focus on full-stack web development. Currently, I’m working at Feedzai
, where I have been contributing to complex platforms such as Case Manager supporting Feedzai's Anti Money Laundering (AML) solutions and building features for managing high-volume transaction screening alerts and their relationships for large financial institutions.
Beyond full time work, I have in the recent years dedicated some time to a project I named Price Lens
-- a price tracking platform for Portuguese supermarkets, with the mission of saving consumers money and raising awareness about purchasing power and price hikes over the years. You would be surprised how much money you can save just from buying at the right time and seeing beyond what shelf labels tell you.
I've been blending my interests and packing them into hopefully useful tools. I'm always open to chatting about new opportunities, so feel free to connect with me on LinkedIn
