Available to hire
I’m Mia Truong, a Senior Mobile Engineer with 8+ years of experience delivering Android and iOS applications across fintech, hospitality, and consumer platforms. Since 2016, I’ve shipped 30+ mobile products, including leading a team of 5 developers at Vingroup to deliver 6 large-scale apps on time. My core stack is Android (Kotlin, Jetpack Compose) and Flutter/KMP/CMP, with hands-on experience in Clean Architecture and cross-platform development. I know when and how to leverage AI-assisted tools like Cursor, GitHub Copilot, and Claude to accelerate development while preserving engineering fundamentals.
I’m currently expanding into .NET and full-stack development through self-directed study, with the goal of growing into a full-stack role over time. I’m seeking a full-time opportunity in Christchurch, New Zealand, with Work Visa (Open) and no sponsorship required. I value pragmatic, high-quality code, rigorous testing, and collaborative teamwork, and I’m excited to bring cross-platform mobile expertise to a new fintech or hospitality product family.
