Здравствуйте Lessie. It's been a long time since I've written a C/V, but I've had to suffer reading through more than a few. It's a bit hard to tell you what to say when I'm not sure what it is you are trying to say. Praxius and Spade noted some key items but I could add a few other suggestions, and maybe a few questions; Is this a sort of mass mail C/V or to you have a particular target in mind? Many C/V's I've gone through are the mass mail type and if nothing notable sticks out and we are not in hiring mode, they just get filed away. It takes a lot more time, but if an applicant has made the effort to research the targeted company and makes their C/V and cover letter more personal it gets more attention.
Saying you were instrumental in developing this project and what your responsibilities and duties were is a good start. It might be risky, but you could ask the organizer or supervisor of this project if you could use them as a reference. I would only use them if I were targeting specific companies or departments within your present company. The risk lies in the fact that once you ask them to be a reference they will know you plan on leaving, this could be good or bad. Always confirm your references before you put them on a C/V, we do call them without asking you first.
You didn't say where you were planning on going, whether it is another department in your organisation, another firm or another country. Knowing the culture of your target helps; Although there are societal cultural differences between Canada, the US, and Russia, corporate culture can deviate from what could be considered the norm anywhere. I can't speak to corporate culture in Russia, but here, being a team player is what corporations look for. While team building is what they say they want, empire building, sadly, is what really happens, at the older and more established firms anyway. Selling yourself as a team player is the best route; many supervisors have reached their level of incompetence and need people who will make them look good, they don't want those who will threaten their tenure by being or looking better than them. It can be an art finding the right balance of tenacity and humility to get you in the door.
Another thing is that unsolicited C/V's and resumes to large establishments end up in the HR, or Human Resources Department, (we call it the Human Remains Department, but I digress). To be fair, these folks have to sort through plenty of applications for anything from mail room clerks to highly trained professional positions they have absolutely no knowledge or understanding of. Our company has a program where employees are encouraged to pass along C/V's of qualified friends or family members directly to the appropriate department head. To save your efforts being lost in the HR abyss you have to research each company you want to apply to, find the head of the department you want to work in and apply directly to them. Most often this requires some effort to get past the switchboard for an introductory phone call. A follow up phone call after you've sent your C/V will keep you in the mind of a prospective employer.
I'm not sure what industry you are in or what kind of project this was either, how you present yourself depends on who your audience is. I'm not prying, but just a little more information can help with the wording of what you want to say.
