🚀 I work with async-friendly, trust-based teams around the world — remote, hybrid, or on-site.
I focus on delivering accessible, maintainable, and intuitive interfaces — translating UX thinking into aligned frontend–backend flows.
My work often involves defining API contracts from frontend needs, aligning logic with data shape, and reducing ambiguity between designers and backend engineers.

💡 My approach combines:

• Frontend development (React / Next.js / TypeScript)
• UX-driven architecture and async-friendly component structure
• API contract definition and integration based on frontend logic
• Clear communication in distributed, trust-based teams

Practice your own answers out loud — built with accessibility at the core.

Whether working independently or as part of a distributed team,
I focus on clarifying requirements, sharing ideas early, and delivering code that respects users and teammates alike.

🔍 I’m currently deepening my accessibility practice — learning to design and build with inclusion from the start.
I see accessibility not just as a checklist, but as a way to sharpen engineering, UX, and real-world care.

📖 I also write about what I learn — mostly on accessibility, UX, and designing with care:

• What Building My First A11y-Focused App Taught Me ↗
  Featured in JavaScript in Plain English, a major publication for frontend developers and JavaScript practitioners.

• From Universal Design to Personalized Interfaces ↗
  Featured in Bootcamp (UX Collective), a curated UX publication reaching 3M+ monthly readers.

• The UX Lesson I Learned in a Quiet Tokyo Salon ↗
  Also featured in Bootcamp (UX Collective), and later selected for Boost, Medium’s editorial recommendation program.

🧠 Recently, I’ve been working on:

• Designing and implementing frontend architecture in async environments
• Aligning UI logic with backend structure and defining API contracts
• Building modular, maintainable UI components from Figma
• Translating design insights into testable, clear code with documentation

I’m especially passionate about clarifying logic across layers — from user flows to database design — to build products that feel simple, even when they aren’t.

Thanks for stopping by!
