I am a ProZ.com Certified PRO (professional) translator and scientific editor/proofreader. I can send you CERTIFICATE, REFERENCES and samples of my translations in any field if required (find attached one).
For example, several times, I have translated scientific materials for the United Nations Organization, and I can send you samples of such translations if required.
For 25 years, I worked as a freelance translator and a scientific editor/proofreader of technical, scientific and other texts from English into Russian at the state magazine “Изобретения стран мира” (“Izobretenia Stran Mira”) in Moscow. In that period of time, I translated more than 25,000 pages of English texts.
I want to offer my services in translating technical, scientific and other texts among English – Russian - Ukrainian.

RESUME
Name: Boris Zeltser
Education: higher education (M.Sc.). I graduated from Moscow Aviation Institute and was qualified as a mechanical and aeronautical propulsion engineer. Diploma (honors degree) No 495802.
Professional experience in translating:
For 25 years, I worked as a freelance translator and a scientific editor/proofreader of technical, scientific and other texts from English into Russian at the state magazine “Изобретения стран мира” (“Izobretenia Stran Mira”) in Moscow. In that period of time, I translated more than 25,000 pages of English texts. During the last few years, I have been doing translation work for the US and GB translation companies.
I have a REFERENCE (a signed and sealed letter in Russian translated into English) from the editorial board of this magazine. If it is of interest to you, I will send it to you additionally.
My translation process involves not only a translation, but also editing and proofreading the translated text by myself.
Therefore, my translations into Russian need no editing and proofreading.
