Oikumena работает по всему миру

Why ‘Oikumena’?

Oikumena, in Ancient Greek, means the known, inhabited world — the space where people live. And the world is one; it should not be divided by borders or nationalities. We strongly believe that everyone has the right to live, learn, and work wherever they feel comfortable and inspired. Through our work, we help erase boundaries and foster better understanding between people.

Hi! I’m Maria — the person who’ll help turn the language barrier into a pleasant stroll. I’m a certified court translator for Croatian and Russian, a member of the Croatian Translators Association, and the founder and lead translator at Oikumena.

I’ve lived in Croatia for over 20 years and know firsthand what surprises a new language environment can bring. That’s exactly why my mission is to make your adaptation smoother, more comfortable, and free from those ‘Oops, I got a bit lost there!’ moments.

I believe that language is more than just words — it’s a bridge between cultures. By helping people understand one another, I don’t just translate documents and phrases — I dissolve boundaries, eliminate misunderstandings, and create space for harmony and collaboration.

Welcome to a world where language challenges aren’t a problem — they’re an opportunity!

What Matters in Oikumena’s World

01

Love for Croatia and Its Culture

I’ve been living in Croatia for 28 years — I came here for work, but stayed for love. I was won over by the people, the climate, and the relaxed pace of life — so different from hectic Moscow. Now I help others adapt and feel at home here!

02

Translation as the Art of Communication

I truly love what I do, because translation is more than just words. It brings cultures closer, breaks down borders, and helps people understand each other. That’s why I never use machine translation — only real, human language and careful attention to detail. And yes, it always shows in the quality!

03

Transparent Pricing and Impeccable Quality

The cost of translation depends on urgency, volume, and topic — but it always remains flexible and individually agreed. We guarantee professional style that stays as close to the original as possible, respect for deadlines, and excellent quality. And if anything needs to be revised, we’ll do it quickly and free of charge!

04

Personalised Approach to Learning

Everyone learns languages differently — that’s why I adapt the method to each student. I take into account their level, goals, and even learning habits. Language isn’t just grammar, it’s living communication and culture. My goal is to help you feel confident and free in a new language environment! Lessons are available in Russian, English, or Croatian — as you prefer.

Original Lectures by Oikumena

For me, lectures are another way of bringing cultures closer together. For many years, I gave free public lectures in Croatian on history of Russia, and in recent years — a separate course on history of Ukraine.

For me, lectures are another way of bringing cultures closer together. For many years, I gave free public lectures in Croatian on history of Russia, and in recent years — a separate course on history of Ukraine.

History is a complex and often contradictory field, but in my lectures I always tried to present facts I consider undisputed. I presented my interpretations and links to other events as possible versions, always mentioning alternative perspectives as well.

Analysing events, exploring cause-and-effect in the historical process, and trying to view everything through a scientific and historical lens — that was my approach to building these lectures. They attracted 50–60 people each time, and I still keep in touch with many of the attendees.

Andrey Klochkoff, Gotek Group of Companies

Moscow, Russia, April 24, 2016

Maria is a true professional! She was a great help to us during negotiations. Our industry is quite specialised, but Maria prepared thoroughly in advance and quickly grasped the subject. A good interpreter is key to successful negotiations — and Maria is an excellent interpreter. I highly recommend her to everyone!
