    I'm ambitious and dedicated to whatever comes my way. I always find creative solutions to tackle issues that arise with clients. Due to my perfectionism, these solutions are usually the most optimal resource and time wise. I'm very well able to communicate clearly with clients to understand their needs and translate them well into the final high quality product, being also able to suggest brainstorm and suggest ideas to save resources and improve the product's final features and usability. Most Importantly, I am truly passionate about my work, and find pleasure in being challenged and put to my limits to find unorthodox and out of the box fixes and features for the product, I'm not looking to just fit deadlines and pass by tasks, I'm hoping to deliver the best possible product that best fits the criteria requested by customers

    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.

    I have mostly been as an embedded software/firmware engineer focusing on Android and Linux. I also worked in early days on Windows software for POS in Delphi and .NET (C#). In addition, I can make good mobile user applications based on native Android. I'd personally hope to acquire Flutter as my secondary specialty asap. It's not that easy though :) Regarding native Android app development, Java is my preferred language but I can also do with Kotlin quite a bit. I have just started my Upwork career and look forward to great relationships! Thank you for visiting my profile.
