Available to hire
I’m Phill Valoyi, a mobile developer with 8+ years of experience specializing in Android (Kotlin, Jetpack Compose, Retrofit, Firebase) and cross-platform development (Flutter, Compose Multiplatform). I build, scale, and maintain mobile applications with hardware integrations like RFID and barcode scanners. I thrive in Agile environments, lead CI/CD initiatives, and focus on delivering high-quality user experiences. I’ve led product-driven teams, collaborated with designers and PMs, and enjoy turning complex requirements into intuitive, reliable apps.
I’m passionate about UX design, prototyping, usability testing, and creating interfaces that are a joy to use. When I’m not coding, I enjoy learning new technologies and mentoring teammates to ship impactful mobile experiences.
