At Flash Pharmacy, I own delivery of mobile product features from requirements and technical discovery through QA, release, and iteration. I’ve designed reusable networking infrastructure and implemented real-time WebSocket chat for healthcare experiences that include doctor consultations, prescription workflows, and Apple Health integration.

At CarDr.com, I led development of BLE-powered diagnostic products including OBD IQ and Trade Scan, integrating vehicle diagnostics, OpenAI APIs, and analytics. Earlier, I developed and maintained iOS products at Xicom Technologies and Quadrish Innovation, working with Swift, Objective-C, UIKit, and Firebase.
