Technical Architect, Technology Evangelist
02 / 2008 - 03 / 2016
Conducted multitudes of technical strategy sessions and projects, supporting needs of $60 billion company. Designed and personally created various parts of Omega project, it's a set of Oracle E-Business suite based apps, a central backend processing unit of company's trading and accounting infrastructure. Dell has one of largest and most complex Oracle Apps instances in the world. Authored multiple Proof-Of-Concept technological sessions to access the business value of new & emerging technologies.
Some projects examples:
Large-Scale search engine + fast data storage for orders, invoices, products and customer data, more than 150M records searched & indexed & updated in near-real time. Thousands simultaneous search & data requests from end users & applications.
Designed the architecture & engine for streamed data extraction & data conversion & transaction-safe storage & retrieval of the aforementioned data. All stages from Proof-Of-Concept to Production ready solution. Search engine is based on Apache Solr + custom-made request handlers, Hadoop + custom transactional engine, Oracle NoSQL cluster.
Scalable cache &distrubuted computing solution based Oracle Coherence In-Memory Data Grid, able to scale up/down without reconfiguration or downtime under high load. Proposed & led the development & implementation of the aforementioned architecture, including data extraction engine, cache infrastructure, user and admin interfaces, connectors for various business application & data flow protocols.
Development and customization of various AR/OM components.
Responsibility: Worked on automated order/products data processing. Proposed & implemented performance & functionality improvements over various stages of Dell custom order workflow code at OM and AR modules.
Implementation of the streaming import data daemon and set of tools in a form of FSM (finite state machine) for high density datastreams at oracle Apps OM product interface. Project first was implemented & deployed as a compiled binary, then Java version has been made.
