Hello, nice to meet You! Seeking for Android App developer?
I love to convert Your idea into app, that not only “gets the job done”, but also provides a Value for You, Your Brand and Your Customers.
“Happy Customer leads to more Customers” - one of things, that I always keep in mind during development of software.
I’m an experienced software craftsman for Android devices, who enjoys smartphones, tablets and gadgets and who loves to convert the ideas into robust, good-looking and as lightweight, as possible, apps.
What features You want to have in Your app?
Want to personalize Your services by knowing user’s location?
Or Your app needs to sync it’s data across user’s devices and provide him/her a convenient access to his/her data?
Or You have a set of unique, maybe even non-standard, features, that highlights Your app among competitors?
Or etcetera?
Let’s discuss Your project details and then You can relax and leave me the hardest part - implementation of Your ideas. I will also propose my ideas and improvements for Your Android application.
If You are not sure, which features Your app will have, I can help You to create technical requirements for it. And I'm open for discussions in Upwork's chat and video-chat.
