.NET Architect & .NET Developer & Architect & C# Developer & Java Architect & Java Developer & Javascript Developer & Oracle Developer & Scala Developer

Senior Java, .Net a C# vývojár a architekt s viac ako 15-ročnými skúsenosťami v IT a v zahraničí. V rámci svojej súčasnej spoločnosti pracoval na 3 projektoch. Jeden, ktorý bol zameraný pomerne do hĺbky. Mnoho spoločností v Nemecku a Rakúsku posiela faxy, pretože ide o právne uznávaný dokument. Fax manager je aplikácia na správu faxov na prevádzku, ktorú používa niekoľko spoločností. Projekt bol realizovaný spoločnosťou BE programming, kde prepísali staršiu aplikáciu do Java EE, urobili integračné testy, ako aj ladenie výkonu. Boli tam veci ako konverzia pošty a faxu a prispôsobenie novým štandardom.

Jedným zo zaujímavých projektov bolo nasadenie nového systému pre švajčiarskeho klienta vo verejnej správe. Chceli urobiť riaditeľský model na internetový informačný server, kde mali starý systém, v ktorom boli uložené niektoré dokumenty. Vytvorili nový systém, v ktorom boli tieto dokumenty rozmiestnené na rôznych miestach a podľa určitých pravidiel, keď niekto zadal požiadavku na starý dokument, prepočítal sa a nasmeroval danú osobu na nové umiestnenie tohto dokumentu. Odtiaľ sa v rámci tohto internetového informačného servera používal .net a robilo sa rozhranie REST API. Pracoval s databázami Mongo DB kvôli veľkému výkonu v systéme. Tam urobil kompletnú inštaláciu tohto servera, na PC server Windows a implementáciu Mongo DB. Pracoval aj s databázami ako SQL a Oracle. Okrem toho robil architektúru riadenú udalosťami pre obchod s módou. Pracoval s Netflixom, Spring Cloud, jadrom .net a používal orchestráciu mikroslužieb, ako aj zasielanie správ. Venoval sa tam aj zasielaniu správ. Pracuje agilne v Scrume, kde majú šprinty 2x týždenne. Plynule komunikuje v angličtine a ešte lepšie v nemčine. V minulosti bol vedúcim tímu, ktorý mal na starosti 4 vývojárov.
