Android Developer

Vývojář pro Android, který se vývoji věnuje od roku 2018. V současné době pracuje na aplikaci pro zdravotní pojišťovnu. K tomu také pracoval n a interní firemní aplikaci Lifestyle, kde se vytvářely různé výzvy mezi týmy a jednotlivci. Prostřednictvím API získávali data z Google Fit a zaznamenávali je do interní aplikace. Pracuje hlavně v Kotlinu, v Javě prý vyvíjí spíše starší aplikace. Má také zkušenosti s RXJava, architekturou MVI, Jetpackem, Coroutines. Zajímá ho práce s databázemi, aby uživatelé aplikace nemuseli být neustále připojeni k internetu. Na podobném tématu pracoval ve své diplomové práci a rád by se mu věnoval, pokud bude mít příležitost. Má zkušenosti s agilními metodikami Scrum i Kanban. Komunikace v angličtině mu nedělá problém. Měl také možnost školit mladší vývojáře.
