Fuller runs App Ape, a mobile analytics platform serving Japanese companies, alongside full-cycle digital services (strategy, design, development, data analysis). The tech stack is deliberately split: native mobile (Android/Kotlin, iOS/Swift) paired with backend Go + AWS + Firebase, plus recent Gemini, Claude, and Vertex AI integrations. Hiring velocity is accelerating with 14 roles posted in the last 30 days—nearly all engineering—and a stated focus on server-side skill development and large-scale architecture changes, suggesting the company is scaling beyond single-app analytics toward a broader platform or expanding service delivery.
