I participated in the creation of 7 large projects. In the last few projects I directly engaged in the development of architecture, which allowed to simplify the logic, improve efficiency and optimize business processes. I am result oriented person, that is why I am very attentive to each project in order to get the product of the highest quality
I am looking for an interesting project with a complex architecture

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

A few words about my dream job: low latency, high throughput, high load, big data, distributed, multithreading. Not interested in UI or FullStack!

Reorganized and improved existing tests execution time so that they pass within 30 seconds instead of 5 minutes. Redesign of shopping cart to support wish list and saved cart functionality, application integration with social networks and loading time speed-up of main search page from 3 sec to 200 ms by implementing product pool cache. Provided RESTful web services for the mobile application, setup automatic build process and integrated it with Jenkins, as well as covered code with unit and integration tests using TDD approach
I am skilled developer who enjoys challenges. I seek position to further expand skills and contribute to a company with creative personnel and challenging projects. My Computer Science interests span several areas including highly concurrent and distributed systems, mobile solutions and full stack of backend application development.

I learned Scala (and other new technologies) ‘on fly’ during the first months of development new game engine and made a number of successful contributions and architecture design decisions. I took a chain of important decisions that lead our product to success. I've encountered a lot of difficulties in my programming way. I've succeeded doing refactoring kilometers of code, investigating memory leaks, reducing memory consumption, decreasing stop-the-world GC time, increasing throughput, mentoring, fixing bugs, implementing algorithmic improvements, etc.
I have a passion for algorithms, mathematics, calculations, artificial intelligence. I adore solving nontrivial, challenging and significant complicated tasks, do researching and apply results for goal gaining. I like multithreading and highload. I am looking for a long-term challenging and interesting project that needs an enthusiastic programmer on board to develop high quality, intelligent software or product. Outsourcing is not interesting.
