About

Who I am

Transforming ideas into reality, one line of code at a time.

I'm a software engineer with a degree in Electrical & Computer Engineering. At work I build machine learning models and .NET microservices for the banking industry, with a lot of attention to unit testing and code quality.

Outside of work I take on freelance projects: portfolios, business websites and custom tools. I like working closely with clients, from the first call until the site is live. If you have an idea, I can help you turn it into working software.
