I develop high quality iOS and Android mobile apps using Swift, Kotlin, Java, SwiftUI, Jetpack Compose, Firebase, and APIs as needed depending on project. Through my hard work and dedication to meet all project requirements, I've earned Upwork's Top Rated Plus rating! I am self-motivated, self-directed, dependable, reliable, and trustworthy. I've been an independent consultant for most of my career. I know how to conceive a project, get the work done independently, and successfully deliver the project. I excel at testing so when the project is done, it is done! No one likes to put together a large programming team where there are tons of duplicated effort and miscommunication. I can be your single-source developer for both Android and iOS phones and tablets! Most apps also need a back-end. No need for a separate web app programmer that can cause timeline problems and miscommunication! I can write the back-end utilizing Firebase then integrate it into all versions of your mobile app. Using a single source, you control the timeline, you avoid integration issues, and everything flows smoothly. You probably cut your delivery time in half! Every week, I develop mobile apps, cloud functions, and cloud tasks, mainly for Internet of Things using Bluetooth and Firebase. Every week, I am using: Kotlin Java Javascript, typescript, node.js (back-end) Swift Jetpack Compose SwiftUI Bluetooth (Android) Core Bluetooth (iOS) Firebase Auth (user authentication, login) Firebase Firestore (database) Google Cloud Functions Google Cloud Tasks (scheduled based on a trigger) Firebase Crashlytics Firebase and Apple push notifications Google sign-in Apple sign-in As an expert Mobile App Developer, other skills I can deliver: Flows, co-routines, async tasks, flow state. WiFi configuration: static IP, dns, enterprise, add and update. JSON serialization/parcelization. NFC tag reading. Develop Maven library. Network Service Discovery (NSD). Direct ipp open protocol for printers. REST - okhttp and retrofit expert for network calls, including calls to Amazon AWS. User accounts with encryption tokens. Encrypted keystore. Push notifications (Firebase, Apple, in-app). Silent package Installer and updater. Kiosks management. Google maps with location updates, custom map markers, annotated map markers. Custom User Interface features with custom graphics, backgrounds, themes, and styling. User authentication. Credit card validation. Stripe credit and debit card processing. Google Pay processing. Glide or Picasso image handling/transformation. Image upload as file or bitmap. Dark mode activation. Launch and welcome screens with terms of service. Multi-threaded environment solutions and multi-tasking co-routines. Dynamic updates of screens from incoming push notifications. Phone dial, messaging, camera photo-taking, gallery browsing. Backwards compatibility to older versions of Android. Forwards compatibility to latest versions of Android. Room database. App publishing on Google Play Store and Apple App Store. App testing on Firebase. Firebase/Maps API keys. Troubleshooting and expert debugging of crashes/bugs/memory leaks in legacy apps. Development environment: Gradle multi-flavor (multi-version) builds Github and bitbucket version control Slack or Jira team communication Figma wireframes Swagger REST API calls Github or Jira project management and collaboration Roll-outs to 50 million user install base A recent review on Upwork: "Stephanie did a superb job to make our Bluetooth hardware on-boarding via Android very reliable. She was able to find the corner cases and then find solutions for those corner cases! This was a difficult challenge as Bluetooth permissions, capabilities, and processes vary greatly between Android OS versions and devices. The on-boarding process is simple, elegant, and extremely user friendly. It has been an honor and pleasure working along side Stephanie." Other: Protocol Stacks, embedded systems, multi-tier networking systems Fortune 500 Java and C/C++ Trainer, Expert Witness Computer Science degree, Certified Project Management Professional Native English Speaker Available to work any timezone Background: I've used many protocol stacks: Point-to-point, TCP/IP, sockets, WiFi CDMA network, Bluetooth, other wireless networks. I've developed application systems with 4 tiers of communication layers: Device to Handheld, Handheld to PC, PC to mini-computer, mini-computer to mainframe. Embedded Systems: Transponder readings sent to handheld which then transferred data to desktop computer which interfaced to IBM mainframe. Cable system "set-top" box. Assembly code for micro-chips. Veriphone credit card readers with communication to mainframes/cloud. Java Trainer for Sun Microsystems (before they were bought out by Oracle) for 2 years. C/C++ Trainer for Intel University (part of Intel) for 2 years. Expert Witness in trial against a top insurance provider regarding their Java based application.

In the past ~ 12 years I was mostly developing Desktop Applications, plugins, DLLs and web services in C# .NET for the mortgage / lending / banking industry. Before that I was working with C++ and developed a sales system for my own sales business which I successfully ran for ~ 8 years. I am well familiar with Windows Servers, Virtualization, hosting, .. and have been hosting / maintaining my own servers for various projects since 2011. As a hobby, I design circuits with ESP32 microcontrollers, and program them in C++. Latest designs also include capacitive touch-screen 240x320 displays which look and work very nice with ESP32's. In the past I used to also develop for Windows Mobile, which was put on pose due to other more important projects. I am getting back into Mobile development by learning Flutter, although I only published 1 application so far.
