START A CONVERSATIONWhy hire me
App Router expertise
Deep production experience with Next.js App Router, Server Components, streaming, and caching semantics. I know when to render on the server, when to hydrate on the client, and how to optimize for Core Web Vitals.
Full-stack on one framework
API routes, serverless functions, edge middleware, and frontend rendering — all within Next.js. I build complete products without the friction of separate backend and frontend teams.
Remote-native collaboration
Structured daily standups, async updates via Slack/Linear, and weekly video check-ins when needed. Based in Japan, collaborating with teams across APAC, EU, and US.
SEO & performance built-in
Every Next.js project ships with structured data, image optimization, font subsetting, and caching strategy. I build products that rank well and load fast.

How it works
Requirements
Definition of content models, complete page inventory, primary user flows, and technical constraints including CMS selection, authentication requirements, payment integration needs, and internationalization strategy.
Design System
Component library built in Tailwind CSS with consistent typography scales, semantic color tokens, spacing systems, and accessibility baselines meeting WCAG 2.1 AA standards — ensuring visual cohesion across all pages and devices.
Development
Next.js App Router implementation using Server Components for data fetching, dynamic route handlers for localized content, API route handlers for form submissions, and headless CMS integration for marketing team autonomy.
Performance
Image optimization with WebP/AVIF formats and responsive srcsets, font subsetting to minimize layout shift, strategic third-party script loading with defer and async attributes, and caching rules tuned for both static and dynamic content.
Launch
Vercel deployment configuration with custom domain setup, staging and production environment separation, analytics verification across GA4 and Search Console, and post-launch monitoring for error rates and Core Web Vitals regression.
