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

As a web developer (Python/Django): - creating complex web applications using such technologies as celery, redis, nats, kafka, jwt auth, and other - TDD approach As web scraping specialist: - Creating spiders to crawling sites of any* complexity - Bypass captcha, bypass Cloudflare protection, NOT selenium approach to sites with a complex Js, use rotating proxies - creating pipelines for the collected data (checking for duplicates, format of fields, etc.) As Golang/Go developer: - creation of high-load projects using the microservice architecture - processing large amounts of data through web sockets api
At the moment I am interested in working with web scraping and data processing

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...

I am a Server Software Engineer with huge experience in making server architectures. I adept in Golang and PHP, but I prefer to use Golang for future projects. Also, I have huge experience in Game Development, Ad Exchanges, microservices, machine-learning. I used a lot of different technologies, for a lot of different tasks. In the case of databases, I have extensive experience in no-SQL databases (MongoDB, Redis, Aerospike, Elasticsearch), and some experience in SQL (MemSQL, MariaDB). I have great skills to works with docker. For CI/CD tasks I`m using Jenkins (have skills to configure and make pipelines). In the case of Clouds, I do not have any preferences. For my own need, I prefer a physical server, but in the real project, I worked with AWS and Google Cloud as well. In the case of queues, I worked a lot with different queues, in cases, when we want to do not make our own implementation, this is RabbitMQ, Kafka, ZMQ, NSQ. In the case of network, I basically use TCP, with its children HTTP layer (include WebSockets), AMQP and some custom socket implementations.
I had a lot of awesome tasks, one of the most interesting tasks what I had, this is implementation RTree spatial index in memory on Golang and AI for the game based on neural network. My personality type: logician "INTP-A", I think this is can be useful. I think that any good programmer can learn any technology, technologies here, this is not a complete list, but here most useful and important of them
Strives to get more experience in Game industries or Bid-systems or Machine Learning, but I guess I can be attracted to other projects if this is something big and cool.
