    I started in mobile development before the invention of the iPhone in a mom-and-pop games company creating the first multiplayer cellphone games for Qualcomm's BREW platform in C and C++. Since then, I've done freelance and speculative work in many languages, especially Java and Kotlin, and created a few apps which can be seen on my app store page, demonstrating the use of Amazon Web Services S3, Lambda, and Cognito integration; TextToSpeech and SoundPool/MediaPlayer resources; and a custom and user-customizable InputMethodService (built-in keyboard), among other things. (See my Google Play store linked below.) I'm seeking jobs to make use of and expand my experience in Kotlin, Android, and AWS and to this purpose I am happy to dive into existing code to solve bugs and insert new functionality, in addition to from-scratch development. Recent and Current Projects: IoT Bluetooth Display and Relay - Android App in Kotlin for phone/tablet and wearable Real-time control, calibration, processing, display, relay, and recording/playback of multiple remote sensors of various types in custom groupings and sessions. Maintaining bluetooth connection through out-of-range and device interruptions. WeeGee - Android App in Kotlin, Amazon Polly, under development Experimental alternative communication system in which touch interaction over custom dynamic menus builds strings of phonemes spoken aloud by the device's text-to-speech engine or Amazon's Polly service.
