Yosuke Sakurai

Founder of Code Your Reality — a digital product studio offering fractional mobile leadership, architecture audits, and full-stack delivery for Android, cross-platform, and web products.

8+ years shipping production apps for e-commerce and banking. Experienced diagnosing production issues—crashes, ANRs, and device-specific failures—using logs, stack traces, and systematic root-cause analysis.

Comfortable across the mobile stack: lifecycle, threading, memory, MVVM, Redux/MVI, multi-module codebases, and Dagger/Hilt in high-availability environments. Recent focus on Kotlin Multiplatform (KMP) and Jetpack Compose.

I work remote-native, timezone-flexible, and async-first. Based in Japan, I collaborate with teams across APAC, EU, and US through structured daily standups, async updates via Slack or Linear, and weekly video check-ins when needed. Typical engagements span fractional mobile lead (2-3 days/week), project-based delivery (4-8 week sprints), or advisory retainers for architecture review and code audits. All contracts start with a one-week paid trial so we can validate fit before committing. Bilingual in Japanese (native) and English (fluent), I bridge communication across international teams and local stakeholders.
