I have more than 3 years develop ios projects with both objective-C, swift. All of projects related location of user and map with many kind of map: google map , mapbox, maply, altus ect... Sometime I develop sdk to intergrated in many apps. All of projects I already finished : spark, kudos, lake luncers , sensorlab, fusion sdk, sojo. For sensorlab it also get some information from apple watch ex : heart beat and send to app on iphone for some special calculator. So with my experiences I can handle and finish your project as well. I also have more than 2 years working with Scrum Framework It really helpful for me to finished many projects.
