Hi there! My name is Marius and I'm from Lugoj, Romania. I'm a curious self-taught developer. I've started learning software development using Java, and web development using JavaScript libraries such as React and Angular. Working in an Agile team of dedicated developers helped me grow, learn and implement new technologies. Together we built viable deliverable products, and inside that team I took upon researching and implementing a testing framework solution (Cypress) thus obtaining good code coverage. I have good communication skills, I'm patient, curios and I'm very motivated to succeed in every project I get involved.
