Mobile development: iOS, Android, and Flutter
I've shipped mobile software since 2013. My own app, Reword Me, is on the App Store now. My accessibility work shipped in the discovery+ iOS app, which has 4.9 stars across more than 912,000 ratings. I've also built enterprise apps at CA Technologies, AR at Verizon, computer vision on Android at Zebra, and apps for IoT sensors. My current Flutter work builds for six platforms from one codebase, and the first branded client build is live on the App Store.

Apps I've shipped work on
- Reword Me (my app, 2026, iOS). An iMessage extension that rewrites an awkward draft before you send it. I built it alone in Swift with UIKit and a StoreKit subscription. It ships in 12 languages and supports VoiceOver, Dark Mode, and Dynamic Type. It was rated 5.0 on the App Store as of August 2026, and the product site is rewordme.ai.
- Westbury Teachers Association (my product, 2026, iOS). A private member portal for a New York teachers union, built on One Group Central, the platform I wrote, and shipped to the App Store in September 2026. Members get contracts and documents with in‑document search, announcements, events, chat, and cryptographically anonymous voting, and it's invite only. The client is Flutter, the backend is C++, and it went through App Store review as a branded single‑tenant build. On the App Store.
- discovery+ (Warner Bros. Discovery, 2020 to 2022, Senior Software Engineer). I added VoiceOver support to the discovery+ iOS app and its tvOS sibling in Swift. The iOS app has 4.9 stars across more than 912,000 App Store ratings as of August 2026.
- CA Flowdock (CA Technologies, 2014 to 2016, Mobile Software Engineer). I worked on the official iOS and Android apps for CA's team chat product, and I built the RESTful JSON and OData backends they called. The apps ran until CA retired Flowdock in 2022, and CA's archived download page still lists the iPhone, iPad, and Android apps.
- TouchID authentication framework (CA Technologies, 2014 to 2016). I shipped the TouchID authentication framework for CA Identity Manager, CA's enterprise identity product. That brought fingerprint login to enterprise identity in the first years Apple let third‑party apps use TouchID.
- AR Designer (Verizon's envrmnt AR/VR unit, 2017 to 2019, Software Systems Engineer IV). I built the AR Designer iOS app in Swift and integrated Cognitive3D spatial analytics. AR Designer launched in April 2018 as envrmnt's platform for adding AR to mobile apps. I also integrated 3D physics into VR, AR, and 360 video services on five platforms, iOS and Android among them.
- Computer vision on Android (Zebra Technologies, 2019 to 2021, Lead / Senior Software Engineer). I led a computer vision project on Android in a native NDK and C++ codebase. I moved the app from a single thread to three threads and improved its rendering performance with OpenGL ES 2.
- IoT sensor apps (Green Energy Research, 2013 to 2019, Principal Software Engineer). I built iOS and Android apps that capture live data from 24 device types over TCP/IP, plot it in real time, and stream video from an embedded single‑board computer.
One codebase, six platforms
Both products pictured are mine, and I designed, built, and run each of them alone. Reword Me is native Swift. The rest of my current cross‑platform work is Flutter.
- One Group Central is a private member portal with documents, events, chat, and cryptographically anonymous voting. The Flutter client builds for web, iOS, Android, macOS, Windows, and Linux from one codebase, and I wrote the C++ server behind it. The first branded build shipped to the App Store in September 2026 as the Westbury Teachers Association app, so the pipeline has made it through store review as well as CI. It's live on the web at onegroupcentral.com.
- Proven Sudoku and Musicianle, my two daily games, are Flutter clients too. Both are live on the web, and the Proven Sudoku iOS release is in progress.
What I bring to a mobile project
- Native iOS in Swift and UIKit, including enterprise auth, iMessage extensions, StoreKit subscriptions, and App Store submission.
- Native Android in Java and NDK C++, with multithreaded capture and processing pipelines and OpenGL ES rendering.
- Flutter apps that build for six platforms from one Dart codebase, with camera capture, on‑device ML Kit text recognition, and push notifications.
- VoiceOver accessibility, shipped in an app with more than 912,000 ratings and in my own app.
- Biometric authentication frameworks, RS256 JWT flows, and subscription billing.
- Computer vision pipelines, sensor protocols over TCP/IP, and AR, both at Verizon's envrmnt unit and on HoloLens 2 at NIST.

Talk mobile with me
I take a small number of consulting projects through NJLIGames Ltd, and I'm happy to compare notes with anyone building for iOS, Android, or Flutter. I'm in Mount Sinai, New York, and I work with teams anywhere.
