SUMMARY
Python Developer with practical experience in Django, Django REST Framework, FastAPI, Aiogram, SQL, and
Git/GitHub. Worked with caching, signals, and Django features to optimize applications. Motivated to grow in web
development (Django, FastAPI), Telegram bots, and asynchronous programming. Strong English (Upper-
Intermediate) allows me to confidently read documentation, communicate with teammates.
Beyond technical skills, I bring qualities shaped by work and life experience: responsibility, resilience, adaptability,
and the ability to stay calm under pressure. I value teamwork, clear communication, and strive to see projects through
to a high-quality finish. And yes, I’m fine with occasional overtime - sometimes it really saves the day, so a bit of “night
coding” is no tragedy for me :)
