After finishing Mathematical secondary school (MIOC) and ETF (Faculty of Electrical Engineering and Computing) in Zagreb, my first significant project was implementation of Mathematical programming model (Revised Simplex method) in order to solve optimal production scheduling problem.

Later I've been applying similar methods from Operations Research and Management Science, Statistics and Neural networks to optimize critical business processes (supply chain optimization, forecasting, financial and inventory tuning...).

More than 2 decades has passed from time when I started to use Oracle, and little bit later Linux and others Open Source technologies.

That experience allowed me to become technical solution architect most demanding European databases, helping some of the Global Fortune 100 companies to improve their operations.

I'm also regular speaker at OUG (Oracle User Group) and member of Europen High Performance Computing society.

Quite recently my web site:

www.josip-pojatina.com

was awarded for one of the best Oracle blogs out there, based on content quality, authenticity factors, uniqueness, data security and a bunch of other aspects.
Blog is considered as reliable and trustworthy and for that reason Expertido added it on its best list.

Although optimization of critical business processes (Operational Research & Mathematical programming) along with performance tuning and design/architecture of large IT systems based on Oracle (Oracle Retail), Java and Open Source technologies still remain in focus, today most of my time I'm spending to solve challenges from Cloud, Distributed System, Machine Learning, AI, Big Data and High Performance Computing fields.
