Designing and implementing generic infrastructure components like Cache mechanism, generic grid, dynamically changed form and more.Deep knowledge of Angular JS framework, how it works and what lies under the hood. Accompanied other teams and co-workers in designing and developing features, solving defects, code reviews etc.I lectured and instructed internal, formal, courses at HPE: Java (4 times) ; Angular (17 times)Act as a "go-to" person and gave vast support for many teams and co-workers on various subject and problems (cross HP products)Primary tools, frameworks and methodologies:GIT, Maven, Spring, Rest (Jersey) JUnit, EasyMock, Web development (Angular, Jquery, HTML5, CSS3), multi-threaded environment, design patterns, functional programming

Generic platform for utilizing processes (GPUP)A Desktop application (.NET based) that enables managing list of items, dependent on each other and perform various parallel tasks while considering the relationship and constraints between the items, sub groups etc. GPUP is plugin based so it could be adopted easily to every domain needed. GPUP was tested and embedded within my working place and was found to improve significantly (by scale of 2-4) the compilation process, testing process and more.Inventory management tool:Desktop tool (Java swing) to manage inventory of models build up from many different pieces. (Lego-like). The system includes sophisticated modeling of the items, sets and building instructions. Support in various queries, what-if scenarios etc.Transportation forecast and analysis:The software implemented mathematical model that pretended to forecast traffic jams over time as function of demands on routes and junctions. The model was explored and used by a master degree student, who used my software to apply the model to various test casesMachine learning experience:Evolutionary based software to solve scheduling problemsArtificial neural network implementation to analyse stock market trends
