About us
Our story
In the early 2000's, ObjectStyle’s founder, Andrus Adamchik, realized there weren’t any good open-source object relational mapping solutions out there. This led him to create Cayenne (now Apache Cayenne) – a framework that helps Java developers efficiently “talk” to databases.
Out of this initiative, in 2002, emerged a company called ObjectStyle, whose original purpose was to help early Cayenne adopters migrate from legacy persistence technologies. ObjectStyle was founded in Atlanta, GA; the company currently has offices in Connecticut, USA, and in Warsaw, Poland.
Over the years, ObjectStyle evolved into a full-service provider that is capable of carrying out complex projects: writing software, performing end-to-end testing and quality assurance, creating complex software architectures, and much more (see our services).
One of our most notable projects is the ongoing partnership with the National Hockey League. ObjectStyle has been developing core software for the league’s main web properties since 2006, as well as supporting dozens of internal business applications.
Open-source projects
ObjectStyle has deep roots in the open source community, and the ObjectStyle team are active contributors to open software.
Apache Cayenne, a powerful object-relational mapping and remoting technology.
Bootique.io, a minimally-opinionated framework for runnable Java apps.
Agrest, a protocol and a framework for flexible model-driven REST data services.
LinkMove, an ETL solution for data synchronization across the components of a complex enterprise architecture.
Programmers can use the above solutions as a comprehensive stack that is well-suited for creating lightweight microservices among other things.
Leadership
Andrus Adamchik Founder, CEO, and Chief Architect
In addition to being a programmer with nearly 20 years of experience, Andrus is also a blogger, conference speaker, open-source developer, and ex-Vice President of the Apache Software Foundation.

A big advocate of open software, Andrus is the founder of such open-source solutions as Apache Cayenne, Bootique.io, Agrest, and LinkMove. In the last year alone, he has made over 3,000 contributions on Github.
Andrus has spoken at Java conferences such as ApacheCon North America; JEEConf in Kyiv, Ukraine; and Joker (the biggest Java conference in Russia). He has also presented at various Java User Groups (JUGs) around the world.

Artyom Kravchenko Team Lead
Artyom joined ObjectStyle in 2013. Initially, he was a Java programmer on one of our company's oldest and most significant projects. As he gained more experience, he started to sometimes fill in for the team lead when the latter was absent. With time, Artyom himself was promoted to a team lead and became fully responsible for the team's operations and client communications.
In his current role, Artyom coordinates his team's software development, QA, and support efforts on a day-to-day basis. Because the team has a lot of unplanned work coming in (it provides technical support to the client's corporate users, among other things), it uses a methodology with elements of Kanban in it, such as limiting the amount of work in progress. Staying focused on high-priority tasks and continually updating tasks priority helps the team effectively develop new features as well as close support tickets.
Artyom holds a degree in Information Technologies and Control in Engineering Systems from Belarusian State University of Informatics and Radioelectronics in Minsk.
Oleg Artyukevich Team Lead
Oleg started his employment with ObjectStyle back in 2013. At first, he was mostly working on the Apache Cayenne project. Then he became a software engineer on one of the client's projects here at ObjectStyle. The team was implementing DevOps best practices to improve time to market and software quality for the client. Practices like code reviews and unit tests were a norm. As the previous team lead moved on, Oleg became the key person on that project.
Right now, he oversees the project by talking with the client's representatives on a regular basis, discussing business requirements, and distributing work between his team members. Since he started, the size of the project and the number of people on it nearly doubled. Recently, the team introduced some elements of the Kanban framework to its work routine to increase transparency and allow everyone to see other people's tasks and availability.
Oleg holds a degree in Economic Cybernetics from Belarusian State University in Minsk.
