C# Developer

Do světa IT a vývoje softwaru vstoupil během studia na Střední škole elektrotechniky a informačních technologií (SPŠE). Po ukončení studia pokračoval ve studiu na Univerzitě Karlově v Praze, kde získal rozsáhlé znalosti z oblasti programování a postupů při vývoji softwaru. Svou kariéru softwarového vývojáře zahájil v březnu 2013 vývojem evidenčního systému pro místní exekutorský úřad. Poté přešel k údržbě malé hostingové platformy pro Minecraft, než si našel novou práci. Jeho dalším zaměstnavatelem byla společnost Orchitech Solutions, středně velký softwarový dům specializující se na portály Liferay, správu identit a aplikace v jazyce Java. Po roce stráveném vývojem backendu přešel k vývoji frontendu a nakonec nastoupil ke svému současnému zaměstnavateli, kde pracuje na jednostránkové aplikaci pro správu nemovitostí.
