Участие в крупнейшем международном аэрокосмическом проекте. Опыт работы с иностранным заказчиком в качестве архитектора. Работа с большим объемом legacy. Вырастил всего двух, но очень толковых разработчиков, за работу которых не стыдно.
Хочу погрузится в проект на 100%, активно участвовать в его жизни и не быть банальным исполнителем команд сверху(снизу, сбоку). Остальное как обычно: Профессиональный рост. Можно стартап. High-load cloud based distributed application

Have more than 4 years of experience working PHP programmer: developing and support Wordpress sites, developing and launching own CRM system. After that started to develop my own projects. Have successfully done a project by contract. Have successfully launched my own startup.
I have developed and launched my own project. 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.

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.
