About

For the last decade I’ve been doing what I am passionate about: digital solutions for businesses. I believe that with the right blend of “get the job done” pragmatism and quality obsession, customer satisfaction is inevitable.

With that in mind, I’ve taken part as a full stack engineer for the digital journey of the industries I worked on. Here are some of them: healthcare, insurance, manufacturing, IIRC, clinical, e-learning, financial, real estate, tracking, billing and invoicing.
