Maintained and added features to the nRF52833 Bluetooth Sensor firmware using C, and Segger Studio and J-Link, and did all the Sensor firmware releases. Alivecor Kardia EKG

As an iOS consultant wrote several new MVVM (Model-View-ViewModel) View Controllers for a medical EKG & Blood Pressure App that was being converted from Objective-C to Swift 4.0. Used Anchor & Visual constraints to layout views with no Storyboards or Nibs. Created and updated Core Data models to support new View Controllers. Used JIRA to close tickets and updated the source using Git Pull Requests.

Cocoon Cam/Health Baby Monitor

Architected and wrote entire Cocoon Cam & Health applications. Both Apps used SQLite and Cocoon Health was entirely written in Swift 4.0. Apps used Redis(https://redislabs.com) to stream video and audio to iOS video hardware decompressor(VTDecompressionSession) and AVAudioEngine for speaker and microphone. Apps could support 10 or more camera streams, and users could swipe between camera’s with video starting instantly on new camera stream. A cloud binary that used neural networks analyzed the video and would calculate the baby’s breathing rate and sleeping patterns. The Activity view displayed the baby’s sleeping analytics along with Gif ’s displaying the baby waking up or crying along with sending notifications for these events. Apps used RESTFul services using Alamofire framework for networking and Codable models.

Architected and wrote the entire Aqueous iPhone water consumption application adding Watch-OS 4.2.3 support along with Notifications and several animations showing water level consumption on both iPhone and Apple Watch. Added Watch complication support so the user can see the water consumption in the watch complications. Watch uses SQLite to store data from iPhone and has very reliable Watch to iPhone communication using WatchConnectivity delegates. Aqueous is mixed language Objective-C Swift application. Aqueous is free on the App Store. Aqueous iTunes Link :https://itunes.apple.com/us/app/aqueous-stay-hydrated/id991272898?mt=8 Cell 408-***-**** Email **********@*****.***

DocSpera

Architected and wrote entire DocSpera medical application for Orthopedic surgeons used for scheduling operations for patients, and chatting with other surgeons and nurses caring for patients. DocSpera has a very sophisticated Calendar with several complicated views for creating and updating surgical calendar events. The Calendar view uses 2D animations for displaying a Month view, time line view, and table view and uses dynamic auto-layout to re-animate the view if the user rotates the device. DocSpera has a very complex chatting application where nurses and surgeons can chat about patient care and diagnosis, and view and edit numerous attachment types including X-ray images and DICOM images. The chat view supports dynamic messaging for creating complex chat bubbles that have buttons the user responds too. DocSpera is a HIPAA compliant and secure application with a fully encrypted database using SQLCipher. DocSpera has Episode of Care to monitor patient recovery time for ninety days after surgery including task updates and messaging. DocSpera supports full view rotations and all iPhone and iPad devices. DocSpera is very reliable for end users who are medical doctors and are very demanding, and usually work in very poor networking environments like hospitals. DocSpera uses 98 complex API’s to communicate with the Server, and all networking is done using AFNetworking with instantiation controlled by CocoaPods.

DocSpera iTunes Link : https://itunes.apple.com/us/app/docspera/id592703908?mt=8 Medigram

Architected and wrote entire the Medigram messaging application. App uses SQLite and SQLCipher as the database, and talks to an XMPP Server for sending and receiving chat messages. The new application was designed to be quickly ported to a new XMPP Server architecture that was to go live in the December time frame. Entire application was started in July, and submitted to App Store the first week in November. In addition fixed the old existing Medigram application which had numerous bugs and stability issues while the new application was being developed. The application used the iOS XMPP Framework to communicate with the XMPP Server which was done in Erlang. Smug Chat

Architected and wrote entire Smug Chat messaging application. Lead developer for Smug Chat a social chatting application. Uses SQLite and SQLCipher as the database, and RESTFul API to send chats from the server over Apples APNS.
