Senior🎓
Top SchoolDaisuke Adachi is a pragmatic full‑stack mobile engineer with 13 years of professional experience who single‑handedly designs, ships, and operates coherent iOS (Swift/SwiftUI/SwiftData), Android (Kotlin/Jetpack Compose), and Ruby on Rails stacks. He specializes in taking products from concept to App Store, Google Play, npm, and OSS—examples include Printora, My Texas Method, and the NativeAppTemplate suite—often using Claude Code as his AI pair programmer. Daisuke builds production-grade tooling as well: a Claude Agent SDK CLI that scaffolds 3‑platform apps with multi-agent verification and a Rails multi‑tenant SaaS API used across his projects. He has shipped security‑sensitive work too, delivering a Ministry‑spec Japanese Residence Card NFC XCFramework validated against real government test cards. Comfortable with high test coverage and automation (hundreds of unit tests, CI-driven test runs, UI vision scoring), he prefers roles where agent‑driven workflows accelerate reliable shipping. Based in Saitama, Japan, he’s open to full‑time, contract, or collaborative opportunities.
