Dear language learner,

My name is Kateryna Boyko, although many people know me as Kate Boyko. I am a Ukraine-born, Japan-based English teacher who has been sharing my knowledge of and passion for the language since around 2010. At that time, I was still a student at a pedagogical university, but I had already discovered how exciting teaching a foreign language can be. I was fortunate to be approached by my very first students, who placed their trust in me and my private tutoring, and I will be forever grateful for that honor.

Over the years, I have taught an ever-growing number of learners with diverse needs, proficiency levels, and backgrounds. For my students, it was about studying, improving, and expanding their skills. For me, it was about the same, because when one teaches, two learn. I have had the privilege of teaching people from almost every part of the world, and as of 2026, my students have represented around 30 different countries. Needless to say, this experience has made me not only a better teacher but also a better person – more culturally aware, broad-minded, and open-hearted.

At this stage of my journey, I am returning to my roots as a private tutor after spending 6 years with an IT consultancy company, where I primarily taught employees business and IT-related English, grammar, and specialized courses such as English for Negotiations and Presenting in English. I am excited to embrace the challenge of teaching people from all walks of life once again, each with their own unique needs, goals, and learning journeys.

If you need help with your English, whatever your goals may be, or if someone in your family or circle of friends is looking for an English tutor, feel free to drop me a line. I will do my best to reply within a day, and if needed, we can schedule a call to discuss your goals and how I can help.

This blog is my hobby and my way of reaching a wider audience of intermediate and advanced English learners who want to deepen their understanding of grammar and vocabulary – areas that I personally find fascinating – while also discovering useful learning strategies, practical tips, and advice on how to study more effectively.

I sincerely hope you enjoy this online resource, which I started back in 2016 and which has gone through several transformations since then.

Whatever brought you to this website, I hope you find exactly what you are looking for here. Good luck with your English journey, and my warmest wishes to you!
