Java Developer

Vývojár v jazyku Java s 8 rokmi skúseností v komerčnej oblasti. Spočiatku jeho pracovná úloha zahŕňala klasický BE vývoj, neskôr mala prienik s DevOps - napr. nasadzoval na AWS, používal Terraform a postupne sa dostal do úlohy Product Ownera a Tech Leadera. Komunikoval s technickými ľuďmi na strane zákazníka, jeho úlohou bolo preosiať požiadavky, navrhnúť riešenie a potom ho pretaviť do kódu. Bol tiež akýmsi "vývojárom poslednej inštancie", keď si tím nevedel rady, radil sa s ním. Podieľal sa na implementácii mikroslužieb (Java, Spring), transformácii údajov z relačnej databázy - používal Oracle, SQL, Kafka, DynamoDB, revízii kódu, budovaní pipeline v Jenkins, Github, Codebuild. Skúsenosti s prácou v agilnom prostredí, v rámci Scrumu mal šprinty, stand-upy, štvrťročné ceremónie, retrospektívy atď. Schopnosť dohovoriť sa anglicky v IT prostredí.
