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.

- Speeded up performance by updating DB and caching APIs from 1200 to 1800 req/sec. - Implemented UA and Advertising platform for 10+ partner APIs with scheduled data pulling using Cron and Kubernetes - Developed of domain language API for models and contracts definition which support client and server parts (minimized typos and code base duplicating) - Decreased build and publish time using Docker containers and Docker Compose to define testing dependencies and isolate them, which gave a speed increase from 20 to 12 minutes

For the last 5 years I am working with Scala web projects. Main library at use is Akka (actor, cluster, streams). Database is distributed embedded key-value storage on basis of akka-cluster.
Scala, Akka, NoSQL
My biggest achievement is gradual migration of project which had required a dozen of senior developers to simpler solution which now can be maintained by couple of middle ones. All changes were done on production systems and clients have very positive feedback about changes. Bugs and performance issues have become a rarity. Along the way the product expanded its functionality and introducing of new features takes of magnitude less time now.
