“In an era where data is now considered the highest commodity; there are few individuals who have the insight and depth to take the complexities of the science of data and shift it into an environment art. Oleg Onegov are one of the few individuals who is entrusted with a deep capacity to learn and retain knowledge; while simultaneously fostering his environment for inclusive sharing. His professionalism, high technical aptitude, moral compass, strong activist for personal development (I believe he’s a triathlete) are all contributors to his pursuit of operating always in a spirit of Excellence. Any organization, institution, company and/or person who encounter his presence will truly be The beneficiaries. His subtlety quietly challenges those who deem themselves of importance; While awakening those who unknowingly have a desire to learn more. Those who highlight the best in others, usually tend to be high performers, such as Oleg Onegov. ”

Enterprise Service Desk System on Atlassian JIRA
Designed and implemented an Enterprise Service Desk System on Atlassian JIRA.
A processing workflow was created from scratch. To fulfill all requirements new issue types, statuses, resolutions, events, project roles and groups, security permission schemes, notification schemes, dashboards, screens, screen schemes, custom fields and filters were created. This system was integrated with a Java portlet located on corporate portal via JIRA REST API.

This system was integrated with a Java portlet located on corporate portal via JIRA REST API.
A Java plugin was developed to move issues via transitions.
Main plugins used for this project are Service Layer Agreement plugin Valiantys VertygoSLA to track SLA metrics, JIRA Enterprise Message Handler (JEMH) to handle mails from external JIRA users.
Other plugins are used to setup workflows, a data model, UI: JIRA Suite Utilities, JIRA Misc Workflow Extensions plugins to extend workflows, JIRA Toolkit Plugin to create some custom fields, Field Security Plugin to make some fields secured, Behaviorus and Script Runner to run Groovy scripts, Dashboard distribution plugin to make available dashboards for user groups.Other creators -

We designed and developed an Enterprise Information System for one of a huge Russian mobile operator using IBM WebSphere stack. We developed portlets using IBM Portlet API and JSR-168 specs. I designed and developed the following portlets: Glossary, Corporate News, Company's Offices, Quizzes, Weather forecasts, Currency exchange rates, Country's Regions, etc. Also I implemented some core WebSphere Portal modules to support using plain servlets inside IBM Portlet API portlets to download and upload files, made the Spring Framework and Spring MVC integration. I created DBUnit like testing framework for an integration testing of modules with databases. It improves the continues integration for modules with database interactions: a testing database schema is locked, after that tables, views, indexes, triggers are created, insert and update queries are executed and a database is populated by testing data, module tests are executed, after testing a schema is dropped. I developed two versions of a portal search system. In first version to search through a portal content I used OracleText for full-text indexing the content of portal and portlets content. To increase of indexing performance I designed and implemented the second version of a portal search system based on the SOLR search and full-text indexing server using a Lucene search framework. The server run on Tomcat server and indexed data and returned search results very fast. All required data were stored in search indexes and ready to be shown in a search results portlet without a need to get data for each found record from a database to show it. It improved the performance of searching in several times comparing to the OracleText solution.
