Smart, concise, highly responsive & responsible person, and rapid learner. I'm primarily working with European and US companies through Upwork, but I am also interested in working with Ukrainian clients. I have great experience in developing complex systems (automation tools and distributed platforms, parsers, crawlers, real-time applications), browser extensions (simple browser extensions for slight enhancement of a user experience on sites, parsers, data scrapers, complex tools), bots (telegram, discord, social networks), and even more. I know that for the Ukrainian market, my prices might be high, but it's not my target market anyway. And I bet my experience and skills are worth it because I can provide the best solutions for your problems. My key skills are: Programming languages: TypeScript, JavaScript, PHP, SQL Database technologies: MySQL, PostgreSQL In-memory storages: Redis Message brokers: RabbitMQ Version control systems: Git (GitHub, GitLab, BitBucket) Server-side: Nginx, docker, docker-compose, php-fpm, vim (I know how to exit, for example xD), ufw, iptables, bash Browser: automation with puppeteer, browser extensions Have strong expertise in the following: electron, nw.js, discord.js, OpenAI API

My name is Oleksandr Velikiy, I'm a backend developer and lately I specialize in Python and Django.For the last 2 years, I have been working full-time in a Ukrainian outsourcing company as a Python developer. During this time, I took part in the development of 2 projects. Both are quite large and have been developed and supported for more than 2 years.Before that, I worked as a freelancer (partially) for 5 years, mainly on this site and with regular clients. Had several long-term projects from regular customers.I have a higher education, graduated with a master's degree in System Programming in 2001. I have more than 7 years of experience working with Python.I have experience working with multi-threading, experience designing systems, writing desktop applications using the QT library, writing parsers using the Scrapy framework, t ried using FastAPI, Flask and so on.Before Python became the main programming language, I developed in C++ (a long but long time ago). Recently, for about a year, in addition to Django, I've been doing full-stack development using React - I've learned JavaScript and TypeScript, CSS layout and front-end development.I have experience working with the necessary tools for developing testing and deploying projects.I take my work as seriously as possible and try to perform it as well as possible.My father used to tell me: "Try to do well, bad things will turn out by themselves." :) I always try to do just that.I have experience working in a team and managing a team. I believe that the team and people are what the company should value the most.
