My work history

I've started my journey with programming back in 2016 on Silesian University with C++ (basics) and Python (basics + NumPy), which I mostly used to analyze and simulate results of different experiments. I've also got some experience in creating basic drivers. Later, after I'd finished my studies, I decided to go in the different direction. I lived in London for a year and was learning web development on my own. In 2020 I'd managed to get an internship and worked as a trainee Full-Stack developer (PHP, JS React, MySQL, Rest API). Since then, I have been working as Front-End React TypeScript Software Developer.

Building on my own a responsive web application, which had a catalogue of all company's servers, displayed in the tree structure. Server's data was taken and parsed from XML file to JSON. Anyone logged could browse through lists of servers. Search and sort by name function were applied. App had system of accounts as well. Admins, technical and user ones. Admins could manage accounts by editing them, deleting and authorize (every new user had to be authorized by admin). Admins could also see what user is logged at the moment.

Main responsibilities:
- designing both frontend and backend side of the app,
- creating an asynchronous communication between client and server via REST API,
- setting up server with database.

Languages: JavaScript, React, PHP.
