I worked on production-grade React Native applications across the full development lifecycle, from planning and implementation to testing and release. I built cross-platform features using TypeScript and integrated native modules in Kotlin/Java and Swift to access device capabilities. My work emphasized accessibility and usability, delivering inclusive experiences such as overlay interactions and assistive workflows aligned with platform guidelines. I also helped ship AI-powered voice features, including speech-to-text, text-to-speech, and promptable responses, with a focus on responsiveness and reliability. I improved app performance and stability through profiling, efficient state management, and optimized networking and storage. In addition, I contributed to automated testing, CI/CD pipelines, observability, and collaborated closely with product and design teams while participating in code reviews and knowledge sharing.

I developed production-ready mobile applications following industry standards, best practices, and user-centric design principles. My work spanned feature development and maintenance across React Native UI layers and native Android modules using Kotlin and Java, with seamless integration of RESTful APIs. I prepared and maintained technical documentation, including software design specifications, API references, and user manuals. I also supported quality assurance through functional testing and System Integration Testing, collaborating with stakeholders during UAT to triage issues and incorporate feedback efficiently. To ensure reliability and consistency, I added unit and instrumentation tests and contributed to CI workflows. I actively participated in code reviews and agile ceremonies, helping improve delivery cadence, collaboration, and overall code quality.
