    Hello! I am a multilingual, highly experienced professional.

That was the beginning of a very exciting freelance journey. I have a proven record of meeting and exceeding expectations and I always work as if I'm doing the job for myself. Mediocrity isn't something I cope with, so you can expect utmost attention to detail and fast turnaround. Currently studying Marketing management with entrepreneurship and working on my freelancer portfolio. To date, I have successfully completed over 100 research, data and translation projects with a focus on company research. Language certificates: - C1 level in Russian (mother tongue) - IELTS band 8 - B2 level in French I'm also fluent in Bulgarian (mother tongue) and can work my way around in Greek, Arabic and Spanish.
