ABOUT ME

An enthusiastic Python Backend/Fullstack Developer

I've started my developer career in early 2010s, after I found myself being unable to process a large dataset with standart MS tools. Since then I have learned databases, data processing and analysis with R and Python, then discovered the world of Web Development and decided to build my future careed around it.
The very first project was a web-based interface to account laboratory orders and expendable materials for my friend's lab. The second one was a desktop GUI for a scientific articles database, writter in Python + Qt4 and PostgreSQL.
Few years later I discovered some freelance services like Upwork and became a part-time freelancer. Since then I discovered a bunch of new technologies, and now I'm able to build a medium-sized project from scratch in a short time and with a good quality. Being a freelancer was a fun time, with lots of new projects and new connections, but now I'm looking forward and have a desire to share my experience with others.

Andrey was very helpful. He would respond fast and completed the work very fast too! He would also ask if everything was ok and would fix it if I wanted a change. Will definitely work with him again!
