Java Developer

Skúsený programátor, ktorý programuje backend v jazyku Java už viac ako 11 rokov v komerčnej praxi. Medzi jeho najpoužívanejšie technológie patria - Java, Spring, Hibernate, JSP, Struts, JQuery, iReport, Jasper Server, SVN, Tomcat, SQL, Jmeter, Tomcat, Rest. Robil aj jeden projekt, kde boli portlety v Liferay a používateľské rozhranie bolo urobené cez Vaadin, čo sa mu celkom páčilo. Na poslednom projekte mal na starosti opravu chýb, návrh nových riešení a celkovo aktualizáciu na novšiu verziu Javy. Jeho komunikácia v angličtine je na slabej úrovni, ale dokáže prečítať a pochopiť všetku dokumentáciu. Určite uprednostňuje dlhodobé projekty, kde sa môže zapojiť svojimi návrhmi. Pri svojej práci aktívne využíva agilné metodiky, najmä Scrum a Kanban.
