Python Developer

Jirko je veľmi skúsený vývojár s 31-ročnou praxou. Najradšej pracuje s backendovými technológiami, najviac skúseností má s Pythonom, Linuxom, Unixom, SQL a jazykom C. Má rád agilnú metodiku, ale na svojich projektoch väčšinou používal Waterfall. Jeho angličtina je na veľmi dobrej úrovni, ruština a nemčina sú pasívne, v minulosti pracoval v Nemecku a potreboval by pohovor. Má bohaté skúsenosti s vedením tímov, pracoval ako manažér a riaditeľ, je dokonca certifikovaný kouč. Mimo práce externe vyučuje na univerzite. Nemá preferovanú oblasť práce a je otvorený krátkodobým aj dlhodobým projektom.
