As a Senior level backend developer my key areas of expertise are on PHP, Javascript, and Symfony Framework. I am very into domain-driven design, software design patterns, and test-driven development.

Past projects required a close coordination with customers from which I gained a lot of experience in facing all kinds of different requirements and problems.

Working with Scrum or Kanban are my preferred organization methods.
