About me

I am a professional programmer, my main speciality is developing applications using React.js.

In addition to specializing in the frontend, I also work as a system administrator, where for a client in the medical industry I ensure the availability of critical services in public facilities working with the National Health Service.

Working in IT is a passion and hobby for me, not just a duty. There are no impossible things for me. Achieving a goal is just a matter of time and access to documentation.
