About

I’m a Senior React Native Developer with 13+ years of experience building and shipping production mobile applications for iOS, Android, and Web. I specialize in React Native and TypeScript, with strong experience in cross-platform architecture, native integrations, third-party SDKs, APIs, testing, CI/CD, and App Store/Google Play releases.

I’ve worked with startups and established companies across healthcare, fintech, AI, rewards, education, and consumer products. At CopilotIQ, I architected and delivered a unified React Native application across iOS, Android, tablet, and web, helping a team of around 10 engineers ship from a single codebase. I’ve also worked with clients through Toptal, including HUB International, Fetch AI, FairmarketHome, and Scholly, taking ownership of features and projects from design through production.

I enjoy solving complex technical problems, building clean and maintainable architectures, and turning product ideas into reliable, polished applications. I’m comfortable working independently or as part of distributed teams, collaborating closely with product, design, QA, and engineering.

Push notifications
CopilotIQ is a shared-code web and mobile application that enables patients to communicate with doctors through the Twilio Video SDK while providing access to charts and medical data. The platform also includes a web admin where nurses can view patient information and manage patient calls. I built the mobile application from scratch for Android, iOS, and web. The main challenge was supporting multiple platforms, screen sizes (phones, tablets, and desktops), and accessibility settings such as font scaling, since the platform was designed for older users. I implemented Twilio Video calling across Android, iOS, and web, as well as push notifications, CodePush, and Google Analytics. I managed CI/CD pipelines and mobile store approvals, contributed to the React-based web admin, and implemented caching techniques using AWS CloudFront.
