Kirill Leontiev

Oracle developer / Data Architect / Performance engineer


Krasnoyarsk, Russia


I am an experienced Oracle database developer with background in banking, strong problem solving skills and interest in database performance tuning. I started my professional career in 2005 as an Economics graduate with passion in computers since childhood, with my first job on the edge of these two domains – as a junior support engineer in banking IT. Some time later I noticed my growing interest to software, and since that time I’ve been adjusting my career so I could gain additional expertise as a software developer and become more and more proficient in this domain.
