Разработчик Go 🔥 

Kyiv, Odesa, Lviv, Kharkiv · $3000 · 4 years of experience · Intermediate

Привет! Прежде, чем начать свой путь, как разработчик долго искал свою технологию. Во время учёбы в университете попробовал Python, Scala, Go, Dart, Java, Android, NodeJS. В итоге остановился на Android и попытался максимально углубиться в эту технологию. Но, к сожалению, первую работу удалось найти лишь как Java разработчик. Далее по случайному стечению обстоятельств вынужден был в кратчайшие сроки изучить Go, потому что одному из заказчиков нужны были гоферы на удалёнку. С тех пор даже не смотрю в сторону Java. Также на моём пути случился полугодовой вояж в мир JS и первого ангулара. Это были тёмные дни в моей биографии) Недолго поработал на действительно высоконагруженном проекте (20k rps/instance). После знакомства с GraphQL влюбился в эту штуку. Единственное, что имеется проблема N+1 запроса к БД. Моим решением стало использование процедур PostgreSQL, формирующих Json на уровне СУБД. Это дало возможно увидеть на выходе производительность на уровне 500 rps в среднем (клиенты хотели получать огромные Json'ы размером в несколько мегабайт). Последние полтора года кручусь около финтеха. Основной стек: Golang + echo/gin + PostgreSQL. Если очень нужно, могу написать скриптец на Python, но не более. Был как-то даже ментором для начинающих разработчиков. Предпочитаю удалённую работу, т.к. бывает сложно сконцентрироваться в шумном open space. В свободное время занимаюсь с друзьями разработкой (кладбища) собственных продуктов.

Git, Golang, REST API, Unix, PostgreSQL, TDD, MongoDB, AWS, Docker, Redis, Vue.js

– есть опыт менторства – разработка проектов, рассчитанных на высокую нагрузку (5000+RPS/instance)

Использование современных подходов и технологий в разработке (использование современных подходов также подразумевает существование хоть каких-либо налаженных процессов). В идеале - удалённая работа.
