I'm a computer science graduate with a passion for mobile development have industry experience in Android app development. Over the years, I've worked on a wide range of android projects with companies and multiple clients developing high-end applications from starting phase to deployment. My goal is to develop maintainable, easy-to-scale, and pixel-perfect applications. I have also extensive experience working in teams with design architecture, project management tools (Jira, Trello, slack), version control (git), software development methodologies (scrum, agile), and direct communication with clients. I prefer long term contracts and projects that have rich functionality.
