Project you are most proud of:
So there was a sports betting system and our stream work with life matches, in a few words - we get data(goal, passes, etc) from different provides, made business logic on BE side(Java 8, Spring Boot, Postgress, Redis, Apache Kafka, AWS) and send it to FE, the last one visualize it to end-user. Why I'm proud of this project - work on performance(caching the responses, async some flow, hashing input date to restrict duplicates), save resources(scaling, memory, CPU, smart logs using, API, the traffic - AWS expensive :)), creating new microservices from scratch(development, thinking about the impact on system), app monitoring and alerts, support performance runs, made some kind of deployment checklist
Mostly interested in high loaded distributed systems
