Description

Senior Android Developer with 10+ years of experience. I know all about the Android ecosystem and development. In all projects I've worked on, I not only focus on delivering features and fixing bugs but also work on tech debt and collaborate with different teams, even participating in the decision-making process while building new features with the team in charge. I also have experience working closely with REST APIs, so I know pretty much enough from both sides how a mobile app is built from scratch or how it works under the hood.
