Do not walk around the company proclaiming that you are the best. You should, however, not keep quiet about what you have achieved either. Mention your achievements when talking to your boss about what you are working on. You can also send your boss a copy of an e-mail in which you are being praised.
Honestly answer the question whether you are able to keep up with the development of your field. To be in the picture, read professional journals or websites regularly and inquire about the possibility of attending courses or conferences.
Do not bother your boss or colleagues with every little thing. Do not complain about everything either. Rather search for solutions. At the same time, be careful not to get constantly reminded by others about meeting your deadlines or because you are repeating the same mistakes.
Your debts are not a sufficient argument. The only strong argument for a salary increase is your performance and the value you bring to the company.
Try to get familiar with the economic situation of the company. Then visit the website of the Czech Statistical Office and find the latest information on the development of salaries in your industry and region. Job servers such as jobs.cz or profesia.cz publish regular statistics of average salaries, too.
If the above problems are not your problems, you have no reason to be afraid to ask. Although you do not have to get a pay raise now, you do not have to be shy. You can talk with your supervisor about your further career plans openly.
