Started his career as research assistant (marine ecologist, analyst) at the Fishery Research Lab and Marine Research Centre in his native town (Klaipeda, Lithuania) by observing patterns of benthic and fish communities of the Baltic Sea and Curonian Lagoon. Initially employment was a part of university studies. Afterwards it turned out into a more free-form cooperation after he started independent consulting activities in 2000. The consulting activities involved sampling, statistical data analysis, reporting to different governmental bodies (national and international). He has been reading ecology lectures for undergraduate students at Klaipeda university for a couple of years. Since 1999 he has been more and more involved into IT development and consulting activities (LAMP, computer networks, databases, data exploration software development using a range of scripting languages - perl, php, bash, livecode, html/javascript). This naturally evolved into the mainstream activity throughout his carrier and was backed up by both formal (environmental information management) and informal studies on a wide range of IT subjects.

During his later projects he participated in design and implementation of the DAISIE alien species database describing ~50 000 introduction events of ~10 000 alien species in Europe. He collated data from partners in different parts of Europe into a single database and created software to map and explore alien species occurrence and spread in Europe. During the NOBANIS project he has produced and published a few popular alien species profiles. He has implemented a few regional biodiversity resource portals. Currently he works as systems manager at the Employer (4D4Life and i4Life projects funded by the EC 7th Framework). He works in a team of the Catalogue of Life - the database aiming to collect names and taxonomy of all known living species. He is also employed as a leader of a work-package in the i4Life project which aims to bring together all the major global biodiversity data providers and smaller biodiversity databases into a unified workflow that would allow to exchange and update taxonomical parts of databases of all the participating parties.

Since 2001, he has been producing ecological niche/environmental envelope models implemented in GIS (IDRISI, Manifold GIS, and own software) to map species or habitat distributions (probability of occurence of marine habitats or species under certain environmental conditions) for an environmental consultancy Alleco located in Helsinki. These maps were used by the consultancy to plan sampling and produce reports for their customers.Since 2001 has been designing and programming server-side software for LAMP systems. This includes various databases and web-frontends programmed using Perl, PHP or customized Webmin/Usermin. usually this also involves some JavaScript. Also programming crossplatform dektop applications (using LiveCode RAD for it). Different customers - from private research organisations to government agencies that need working systems delivered within reasonable timeframe.As an employee (systems manager) at the University of Reading he did comparison of options, described, chose, ordered and purchased pc and server hardware. Virtualized the catalogue's of life servers infrastructure and introduced load balancing (as well as elimination of single point of failure). Systems management also involved beta testing of the software provided by project partners, building Linux servers, scripting (bash, awk, sed, php, perl), data transformation (ETL).
