I have 2+ years worth of experience creating and maintaining Android Applications from the ground up. Often, before I delve right into coding I make a habit to list down every task that I will do to serve as my implementation checklist. This also helps me in analyzing the project and the features to be implemented, allowing me to generate suggestions or comments for inquiry on the client's Application Design. I also have fun in contemplating for the perfect Code Design, which concerns about the implementation details of the project and helps as a guideline in creating maintainable, developer-friendly code. ... more I am confident in my skills and am interested to learn more so that I could provide efficient, high-quality applications for my clients.
