1) Senior Software Engineer at Adform Development SSP (https://en.wikipedia.org/wiki/Supply-side_platform). - new features development - optimizing code and infrastructure for highload - finding and optimizing hot spots Technologies and tools used: Scala, Twitter Finagle, Kafka, Akka 2) Senior Software Engineer at EPAM System Developed data ingestion flow for large retail company. Involved in processing up to 100GB daily data in Spark on Azure cluster. Part of the data was prepared and queried via Hive. Technologies and tools used: Kafka, Spark (Scala), Hive, HDFS, Azure 3) Senior Java Developer at iFuture On this position I : - developed online casino; - integrated two online games providers; - created CMS for manage stuff like games, banners, promo etc; - developed system for managing transactions; - developed system for reports(profit and loss by users, product etc.); The system itself consists from a bunch of microservices, which communicate with each other via REST or Kafka, and a couple of monolitic services. I used docker for local development, Spring Boot freamework as a DI, WEB, AOP framework, Spring Cloud (Feign and Hystrix clients), JPA (HIbernate as an implementation), Postgresql and Oracle as a databases, EHCache for caching, Redis for caching and zero-downtime deployment. Also, I was in charge of: - monitoring the system (NewRelic, Zabbix); - architecture improvement. Here I was mostly focused on following best practices for microservices development: 12-factor principle, config server, request tracing, choreography over orchestration if it makes sence; - performance improvement: caching slow queries and remote calls, resolving slow queries (Hibernate), - codebase improvement: Lombok, monitoring aspects, unit testing
