Golang developer

Remote work, Estonia · $3000 · 4 years of experience · Intermediate

- post-processing service that could process ~300k rps in peak(Golang, MySQL, kafka, gRPC) - service that selects the best ad for user request less than 20ms(Golang, MySQL) - Data Management Platform(Golang, Aerospike, Protobuf) - service that receives IP in request and returns geolocation data("netacuity" as data provider, Golang and protobuf) - service that collects data from IoT devices and generates reports(Golang, PostgreSQL, redis)

PostgreSQL, Golang, Docker, Linux, MySQL, Git, MongoDB, REST API, go, SQL, JSON, Python, Microservices, RabbitMQ, ElasticSearch, InfluxDB, Backend, aerospike, Redis, Prometheus, Grafana, Consul

In additional to solving business tasks, I also prefer to write maintainable and optimal code. For instance: - Improved primary metric for service(latency) from 50ms to 10-20ms. I really like metrics. Metrics can show you how your application works and shows you problems of your users. I prefer to improve metrics that you can measure instead of subjective metrics - after my optimizations, we decreased count of servers from 10 to 3. - I decreased code lines from 1kk+ to 300k. It made it easier enter to the project and keep in mind whole project - I really like devops philosophy and believe that developer has to write, test and ship code to servers. With this approach I reduced "time to market" metric. Earlier we deployed few features in one big deploy, we had risks. Deploy process was hard and nobody wanted to deploy. Now my team deploys as fast as feature is finished and delivers fixes and features every day

Backend developer (Golang/PHP)

St. Petersburg · $2500 · 6 years of experience · Intermediate

Синьор PHP-дев с опытом 6+ лет. Много работал с Symfony разных версий (2/3/4) и ecommerce платформой Magento. Руководил группой бэкенд разработчиков, занимался настройкой систем CI/CD как для dev/stage окружений, так и на клиентские live сервера. В какой-то момент стало понятно, что больше не могу заниматься просто "сайтиками", хочется/нужно делать что-то более серьезное. Было решено перейти на Go, и я плотно занялся его изучением. На данный нет коммерческого опыта в Go, но есть огромный энтузиазм, имеется понимание многих вещей в го, в том числе pprof, grpc и написано много учебного/академического кода (ну, это такой сферический-в-вакууме код, который практически бесполезен, но при этом требует выполнения какой-то задачи с помощью возможностей языка) Так же мне нравится направление DevOps, однако я не имею достаточно знаний/опыта, чтобы считаться полноценным DevOps инженером

Профессиональный рост. Неформальная обстановка. Интересный проект. Адекватный менеджмент. Возможность удаленной работы. Преимущественно рассматриваю предложения по Go или по Go/PHP. Чисто PHP - нет.

I can't wait to tackle challenging tasks and make a product better. Whether I am a part of a big team or working alone, I value the impact every person can make to achieve the best results in the end. I am looking for a Golang position, really excited to start this new career path! I am willing to develop Web application whether RESTful or gRPC and use algorithms as a daily ritual. My goal now is to find a project with good management and the ability to work remotely. Only backend, only golang!

Профессиональный рост. Адекватный менеджмент. Белая зарплата. Сложные задачи. Интересный проект. Дружелюбный коллектив. Командировки за границу. Удаленная работа.

CTO/Co-Founder

Kyiv · $8000 · More than 10 years of experience · Advanced/Fluent

Skills: - Web Development - Architecture Design - CI/CD integration - Leading and Motivating people - Facilitation of conflicts and holywars - Line management - Understanding Business and Client needs and values - Providing visibility of process. - Experience with highload/highperformance apps - Recruitment (tech interviews)

- Настраивал процессы разработки с нуля в ограниченных ресурсах, балансируя между маленьким бюджетом, требованиям бизнеса, стоимостью разработки, комфортом разработчиков и девопсов. - Вырастил много мидлов из джунов - Вырастил Тех Лидов из разработчиков - Сформировал дочернюю команду - Разработал архитектуру полного CI/CD процесса (после ревью, происходит тестирование, создание динамического тестового окружения, автоматический деплой на это окружение, передвижение задачи в статус "готово к тестированию" после автодеплоя, удаление тестового окружения по статусу задачи "закрыта") - Участвовал в процессе найма, разработки и проверки тех задания - Разработал общую и индивидуальную схему Personal Development Plan на длительный период для разработчиков и тех лидов. - Разработал схему развертывания группы проектов как единое целое, а также создал схему развертывания которая работает локально, на тестовом окружении и проде. - участвовал в разработке двухуровневой архитектуры модульного фреймворка/платформы для создания новых и перевода старых проектов, что сокращает расходы на разработку и поддержку. - разработал систему интеграции магазина одновременно с многими платежными агрегаторами как avangate, payproglobal, stripe, paypal, etc. - разработал систему партнерской программы, для одновременной работы с несколькими сетями как Hasoffers & CJ. Участвовал в проектировании/интегрировании/поддержке таких процессов как: - TDD/BDD, - В контексте интеграции тестов, за год в неспешном режиме, без значительных потерь по времени покрыли все проекты на 70% тестами с нуля. - миграция из kanban на scrum, - создание и поддержка локального окружения, которое имитирует структуру продакшн серверов - наступал на грабли, знаю как делать не нужно. - контрибьютил в опенсорс проекты - пишу блог - изучаю различные языки

Не хочу заниматься с устаревшими технологиями. В принципе не имеет разницы с чем работать, главное в этом всем - стоимость разработки, поддеркжи и минимальное количество боли разработчиков при работе с этим. Было бы неплохо поработать с проектами на Go Но пока сталкивался с ними чисто ради очень маленьких однозадачных сервисов для очень высоконагруженных систем. Не хочу заниматься проектами, основанными на коробочных "быстрых" решениях, такие как magento, wordpress и любые другие подобные cms, cmf и т.д. Т.к. в конечном счете придется это переписывать и это будет очень дорого и больно.
