    I am an expert in rolling out user friendly mobile applications. I have been building iOS apps since 2014. My strengths lie in my core technical skills, my fast flow of communication, as well as my industry experience in working with over 30+ app publishers since 2018. My recent projects include working on a privacy-centric, location aware Software Development Kit (SDK) that was generating visit data off of 400k+ individuals. This experience allowed me to work hand-in-hand with CTOs, project managers, and other engineers to get them to implement best practices and leverage UI/UX to grow their user base. Building apps should be a fun, enjoyable and transparent experience. You should know what portion of your app is being built, at all times. That is why I strive to be the most transparent and communicative developer here on Upwork. I'm extremely fast to respond and have a unique ability to translate technical jargon into easily understandable explanations. I write clean, testable, and reusable code. This means you app's technical architecture is simple and scalable. Thus allowing any other developer easily build upon the app I have built for you. If you've worked with freelance developers before, you understand how this alone can be such a headache.
