Is there any place on Stack Exchange network where I can post some information about a project I am currently working on?
All Stack Exchange websites are Question + Answer sites. The software that powers them is not a generic CMS, but a specialized Q+A site engine, and all sites have a similar policy.
Your project obviously does not qualify as a question. If it already serves as a part of a completely practical answer to some kind of a question asked by someone else, you are free to offer such an answer.
I don't really expect that you would succeed in finding questions that will be directly and fully answered just by pointing to your project; which means that you should not post information about your project on Stack Exchange sites.
Even just looking for such questions may however provide inspiration to your project; you will see a sampling of real questions asked by people in your area. That's the real benefit of the exercise.
Please be realistic when evaluating the possibility of answering a question by "pointing to yourself". Make double sure that you don't overlook an operating system mismatch, previous better questions, or maybe a difference between a market ready library and a tentative project. Do not answer a question just because you are looking for free advert space. The community is known to close such "answers" promptly. Be also very open about your relation to the project, to avoid any doubt about your motives; and stick to facts within the scope of the question.
