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
