PROFILE:
I think that of all my experiences it is worth highlighting the place where I worked for more than a
year, because during that time I really had time to deal with a lot of things. I worked on small projects,
where every next task could require a special approach or technology. And I also spent a year on one
big project, it was a document management application that I had the chance to develop and modify.
Of the features I could highlight were the multitenancy, the tremendous potential for customization
and the incredible amount of interconnected logic. Each module, each page and each field had its own
permissions, as well as users could expand the system with their own entities, which could interact
with existing ones, as well as to link to them, pull them up and use them. This is only a small part and
I could go on and on, but I think it's worth specifying my contribution to it all. At the beginning I
mostly dealt with bugfixing and refactoring of existing modules for optimization or modification,
including customization and permissions. After that, I started to work more on implementing new
functionalities, such as the export fields tree, the export system in general, where depending on the
user's wishes the user had to build his own file style, as well as retrieve all the necessary data,
expanding and optimizing the custom entities (custom fields), adding new types of fields, for example
dates, as well as the ability to specify the format in which this custom field type should be, a lot of
small pages with CRUD functionality.
I left that project because I felt I would be interested in trying something else based on C# and .NET,
so I had my eye on Unity and the potential of C# in gamedev and .NET in the server side of Massively
multiplayer online games, but life decided otherwise. When russia attacked Ukraine I got under
occupation and lost my job. It took me five months to get out to a safe and free place and now I am
looking for something remote to get back to work so I can work without being tied.
