Have some non-commercial experience with Scala/Akka/Spark. I have some experience with Golang and Java. Currently, i work as python/django developer and have more than 3 years of experience. During my work carrier I developed different projects: system for medical recommendations; sports betting platform; cybersports events aggregator; rest api for app like Uber; rest api for dating app; etc.
Create a realtime map with indicators of current meetups in the world. For that project, i use Spark and Spark streaming, for web socket connetions - Akka-http. All data are storing in Cassandra with some processing.
Interesting projects with a professional team without frontends tasks.
