    NodeJS, NestJS, AWS, VueJS Web Developer For the past 15 years, I've been working in web engineering and polishing my skills creating applications of different complexity. Currently, I'm mainly focused on full-stack JavaScript/TypeScript development with NestJS and VueJS. Most used databases: MySQL, Redis. Most familiar infrastructure: AWS Services. SCM of choice: GIT (including GitLab/GitHub) I have experience with serverless solutions, most commonly utilizing AWS Lambda for a variety of background jobs and lightweight APIs. I usually use "Serverless Framework" for these. I also have a good knowledge of PHP. And while I'm not interested in active PHP development, if it is a part of the system or something that needs to be converted to NodeJS I'll be good with that. On the way, I learned many related technologies, skills and concepts like Linux administration for servers and everyday desktop usage, understanding of networking, image manipulations with ImageMagick, Docker, CI/CD, etc... I'm always open to learning new things and happy to do it. My work is a kind of art for me, and I do everything possible to achieve beauty and efficiency in my creations.

Recently, I have been working as a full stack developer (mobile client + .NET backend). I enjoyed developing microservices, so I made a willful decision to quit mobile development and focus on backend. At the current stage of my development as a backend programmer, I don't care what my position will be called and how much money I will get for my work, the main thing is gaining experience. I live in the city of Kyiv in Ukraine and have an ability to work remotely with flexible schedule
