Hello,
I am excited about your job post. It fully matches to my skills and experience in Android development. I can creat Android background service that collects movement sensors inputs for you. I have a strong experience in geolocation based mobile apps. Please take a look at my portfolio. And let's discuss details of the project.
I have over 8 years of experience in mobile development gained during the work terms and through personal projects (social, geolocation based, chat, dating, food delivery, healthcare, education apps).
Right now I am looking for new and exciting projects to work on. I know you've got a lot of low cost candidates, but if you would like to get a high quality result for a good price, you are welcome to consider me.
I am always looking for a long-term relationship based on trust and professionalism. Your Success Is My Success!
I am looking forward for your reply.
Best regards,
