PROFESSIONAL EXPERIENCE
English teacher — Compass learning centre | Lviv | [04/2024 – 06/2024]
In this position I started working with groups of children and analyzing what is the best method of teaching I can imply
for them all to be interested in lessons and not be distracted. My skills in working with CRM systems got better as I
had to fill in all the information about lessons (which included multiple types of data and formulas) into a big Excel file.
English teacher — Justschool | Remote | [08/2024 – 10/2024]
Here my proficiency in operating online tools got much better. Also advanced attentivity took place because of a
huge amount of teaching resources, which I had to look through carefully and choose the best ones to fit the interests and
needs of my students. There was a lot of times when I was asked to be a last minute substitute teacher, so I had to
analyze a lot of information about previous lessons quickly and adapt to students’ knowledge.
Head waitress — Friendly karaoke bar | Lviv | [10/2024 – 04/2025]
In this position my main responsibility was to provide the best experience I could. The main instrument to do so was
deep knowledge of menu and the ability to listen carefully to people and their preferences to choose which dish or drink
would be to their taste. I also had to manage the work of other waiters, fill for them or take responsibility, so it formed the
sense of team and its value for me.
English teacher — Pachka English | Lviv | [08/2025 – 08/2026]
Here I had to deliver to the requests of each student and to improve the specific abilities they chose. Their age,
profession and language level had to be taken into consideration to create the program that would become the best fit in
terms of their abilities and interests. The materials and tools were only of my choice, so it had to be creative and analytical at
the same time.
