Oleg Bartunov has been involved in PostgreSQL development since 1996 (he introduced locale support). He is a major developer and a member of the PGDG. Together with his colleague Teodor Sigaev he developed infrastructure for implementing user-define index access methods GiST and GIN, built-in full-text search facilities in PostgreSQL 8.3 (formerly known as tsearch2) and a number of popular extensions like intarray, ltree, hstore, pg_trgm. Their latest contribution is an efficient neighborhood search in PostgreSQL, which provides scalable solution for many GIS applications.

Oleg graduated from the Astronomy department of the Physics department at Lomonosov's Moscow State University. During his professional work at Sternberg Astronomical Institute (SAI MSU) he realized he needed a free and powerful open-source database like PostgreSQL (Postgres95 that time). Since then he extensively used PostgreSQL in his scientific work and many other projects. Oleg is an active member of Russian PostgreSQL community, he advocated the adoption of PostgreSQL by astronomical community. One of his scientific projects makes use of scalable indexing of multi-terabytes sky catalogues, developed for PostgreSQL, which outperforms known techniques used in commercial databases.

His main interests are Informaton Retrieval, Databases Extensibility, Algorithms and Data Structures, Service-Oriented Architecture for Science and XLDB for Science. In spare time he like to play volleyball, jogging, and he does a little yoga. Last years he enjoy adventure trekking in Himalaya.
