In 2001, 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 emerged a company called ObjectStyle, whose original purpose was to help early Cayenne adopters migrate from legacy persistence technologies. ObjectStyle was founded in Connecticut, USA; the company currently has offices in Bridgeport, CT and in Minsk, Belarus.
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.
ObjectStyle has deep roots in the open source community, and the ObjectStyle team are active contributors to open software.
Programmers can use the above solutions as a comprehensive stack that is well-suited for creating lightweight microservices among other things.
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.
He is one of the few “coding CEOs” who combine writing code with running a successful IT company. In his current role at ObjectStyle, Andrus remains its Chief Architect and is personally involved in a number of ObjectStyle’s projects.
A big advocate of open software, Andrus is the founder of such open-source solutions as Apache Cayenne, Bootique.io, LinkRest, 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.
Andrus Adamchik holds a Master of Science degree in Chemistry from Belarusian State University in Minsk.
