Looking for a team to develop an app and a minimal backend for our wearable Electrocardiogram (ECG) device. It will be very similar to the Garmin connect app, except the ECG will give more detailed and real time information than a simple heart rate monitor. First project scope will be to develop an Android app for phone and tablet, plus a minimal back end, but there will be future jobs for iPhone/iPad version, and the full back end and web app. All work can be in English, but must have multi language support built in, so that I can quickly translate this app into Japanese. SDK will be provided to connect and get data from the device. Must have experience with Bluetooth low energy devices. Wireframe is attached, and function requirement is available for applicants. Applicants should have some UI and UX experience, enough to critique and discuss my designs and make necessary improvements and adjustments.

I have a Swfit app. I need someone to teach me how to make an authenticated request with the Twitter Rest API. I have already integrated twitter using their frameworks, TwitterKit and I can log the user in successfully. However I"m looking for someone to teach me about oAuth more directly. I've already done extensive reading and I understand all the keys that need to be created in the headers. However, I'd like to fast track this feature. I'm hoping it will help me make my own authenticated request going forward. English speaking fluency a must. I'd like to build as we go. I'm hoping this can be achieved in a couple hours, but would like to hear your thoughts. Note: Since I'm using my own UI and I don't want to use the Twitter Composer, I can't use Twitter Kit and need to access the REST API and make authenticated requests manually. Since you will be teaching me, let me hit you with my experience. I'm a learning developer, but I already have an obj-c app in the store. Used SDKs to connect to twitter, facebook. Was using Parse, but now self host a version of the parse server. So I have background, but I'm having trouble with these API calls. You'll just be showing me the syntax and I "should' be able to follow.
