- 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

In LanaLabs (located in Berlin) we were developing the process mining solution and it was incredible. The code was so clean, very nice architecture and I was glad to work for them. Unfortunately, I decided to come back to Ukraine.
I expect to be part of the nice team with nice designed processes and fast developing culture. Would be cool to develop something important for human (in general), environment, disables etc. I have an interested in golang, would be cool to develop something on it, no experience there tho (but its just a language).
