Worked with all part of the project: developing, marketing, marketing automation, team building(finding and working remotely), product design, customer success, etc. Have a great production experience of Go development(using PostgreSQL, AWS, microservices, Vue.js, so on). I'm focused on problem solving with the best efficiency. I'm ready to learn something new, especially if it's needed to achieve a goal.
Want to work with an interesting project, it's better to be own product. I'm interested not only in programming but in BA too. It will be great if my experience of building a startup, launching a product would be useful. Keen on marketing automation, getting clients and so on.

I'm a Python/Golang Software Engineer and web scraping expert. I have deep experience in developing web applications using Django framework. Also, I have 3 years of web scraping & data processing experience. In my projects, I used Scrapy framework and Scrapyd to deploy my spiders. I scraped a lot of websites which using antibots, Cloudflare and complex JS. For more productive data processing, I used the technology of de-coupling processes and asynchrony. As a Go developer, I built highly loaded projects using the microservice architecture

Последние 3 проекта разработаны на языке Google Go с использованием gRPC, Google Protobuf3. Архитектура - микросервисы с оркестрацией на базе consul. Платформы обеспечивают бесперебойную работу 24x7, системы практически живут "своей жизнью", вне зависимости от возникновения критических сбоев системы умеют сами переключаться на "здоровые" узлы сети, не останавливая работу технологии в целом. Сетевое взаимодействие сервисов оптимизировано уникально
Использование новых технологий, изучение новых если в бекграунде еще отсутствует, разработка архитектур систем на базе микросервисов для бесперебойной работы в целом, использование языка Google Go для написания бекендов, работа над высоконагруженными проектами, требующими щепетильного отношения к использованию ресурсов железа, трафика сети...
