C# Developer

Do sveta IT a vývoja softvéru vstúpil počas štúdia na Strednej škole elektrotechniky a informačných technológií (SPŠE). Po ukončení štúdia pokračoval v štúdiu na Karlovej univerzite v Prahe, kde získal rozsiahle znalosti z oblasti programovania a postupov vývoja softvéru. Svoju kariéru softvérového vývojára začal v marci 2013, keď vyvíjal systém evidencie pre miestny zberný úrad. Potom prešiel na správu malej hostingovej platformy Minecraft, než si našiel novú prácu. Jeho ďalším zamestnávateľom bola spoločnosť Orchitech Solutions, stredne veľký softvérový dom špecializujúci sa na portály Liferay, správu identít a aplikácie v jazyku Java. Po roku strávenom vývojom backendu prešiel na vývoj frontendu a nakoniec nastúpil k svojmu súčasnému zamestnávateľovi, kde pracuje na jednostránkovej aplikácii pre správu nehnuteľností.
