Work History

Nov 2016Present

Lead Java Engineer

Evosoft Hungary Kft

As a lead of an 8 developer scrum team I designed and took part in the implementation of a data stream processing workflow engine. This service consists of 10+ microservices, built on top of AWS and Spring. I also designed and implemented the whole CI/CD pipeline which is currently adopted in the organization by 10+ teams. 

I also implemented process enhancements in my team, such as introducing story point based estimation, proper granularity in work item refinement and other measures to help the developer workflow to be as efficient as possible.

I am part of the architecture board on this project for the Hungarian site and represent the Hungarian teams on international forums.

Java Engineer

Ustream, Inc.

As a member of the Streaming Team my job was to modernize it's technology stack and developer workflow. After the services were moved to a container based environment I introduced Spring Framework including Spring Cloud to the JVM based applications. We deployed multiple applications to this platform and the concepts introduced are still in place.

Java Developer

ShiwaForce.com Inc.

Working on karmaplatform.com my biggest accomplishment was leading the transition from a single, monolith application in a private datacenter to an AWS based polyglot microservice architechture without a single point of failure. Building on top of Spring Cloud and Netflix OSS I grasped the fundamental principles behind cloud native applications and high availability. I also took part in developing an Atlassian based delivery pipeline for all of the services.

My latest assignment is implementing the researched architecture at one of the company's most prominent client.

As a freelancer developer I was part of a small team to develop a LAMP private video sharing platform. The application needed a full DevOps mentality, tasks included apart from the LAMP stack development were :

  • Design and implement a video encoding service
  • Set up a linux based server including hardware assembly in a private datacenter
  • Multiple crawlers for competition checking

PHP Developer

Docler Holding

After acceptance through a week long boot camp program I became a part of the SWAT team. Tasks included bugfixing and new feature development on all PHP based products and the streaming servers. The nature of the SWAT team required that we worked in Kanban. The bugfixing was quite challenging since there were multiple services and layers involved with almost every error, it greatly enhanced my debugging skills.
