Web Development
Next.js & modern frontend
Web Development
Fast, SEO-friendly web products built with Next.js, Tailwind CSS, and modern deployment practices.
I work seamlessly with Tokyo and JST timezone teams. Also available in nearby cities: Yokohama, Chiba, Saitama.
Overview
I design and build marketing sites, dashboards, and web companions with Next.js App Router. Every project ships with structured data, performance budgets, and analytics instrumentation from day one so your team can iterate quickly after launch.
What you get
- Next.js marketing sites and landing pages with App Router
- Headless CMS integration (WordPress, Contentful, Sanity)
- Design system implementation with Tailwind CSS
- Performance optimization — LCP, INP, CLS, and caching strategy
- Firebase/Supabase backend integration and serverless APIs

Web projects achieve sustainable success when performance, search engine optimization, and long-term maintainability are treated as first-class requirements from day one rather than afterthoughts added during final QA. I build with Next.js App Router, leveraging React Server Components wherever possible to dramatically minimize client-side JavaScript payload and improve time-to-interactive metrics. Tailwind CSS provides a consistent, utility-first design system that eliminates CSS-in-JS runtime overhead while enabling rapid iteration. Every page ships with schema.org structured data, fully responsive images with modern formats, and strict Core Web Vitals budgets. The result is a web product that ranks well in search, converts visitors effectively, and remains easy for your internal team to extend and maintain without constant refactoring.
Process
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.
Deliverables
- Next.js application source code with App Router architecture
- Tailwind CSS design system and component documentation
- Headless CMS integration (WordPress, Contentful, or Sanity)
- Core Web Vitals report with performance budget compliance
- Analytics and conversion tracking setup (GA4, GTM, or Pixel)
- Deployment configuration and staging/production pipeline

FAQ
What tech stack do you use for web development?
Next.js App Router, React, TypeScript, and Tailwind CSS for the frontend. Firebase or Supabase for backend needs. Vercel for deployment. This stack delivers excellent performance, SEO, and maintainability.
Do you build with SEO in mind from the start?
Yes. Every project ships with structured data, semantic HTML, optimized images, and Core Web Vitals budgets. I treat SEO as a first-class requirement, not an afterthought.
Can you integrate with our existing CMS?
Absolutely. I have experience with WordPress, Contentful, Sanity, and headless CMS architectures. The integration approach depends on your team's content workflow and technical constraints.
How do you ensure fast page load times?
Server Components to minimize client JavaScript, image optimization with modern formats, font subsetting, strategic caching, and edge deployment. I target Lighthouse performance scores above 95.
Do you handle deployment and hosting?
Yes. I configure Vercel deployments with staging and production environments, custom domains, and analytics verification. Your team gets a fully operational pipeline they can manage independently.
What deliverables do we receive at project completion?
Source code with documentation, a Tailwind CSS design system, CMS integration, analytics setup, deployment configuration, and a handoff session. Your team can iterate immediately without dependency on me.
Do you work with teams in Tokyo?
Yes. I collaborate seamlessly with Tokyo and JST timezone teams. Based in Japan, I work flexibly across APAC, EU, and US teams using async-first workflows to minimize timezone friction.
Do you serve nearby cities like Yokohama, Chiba, Saitama?
Yes. I cover Tokyo and surrounding areas within the same timezone. Because I work remote-native, physical distance is never a barrier.
What timezone overlap do you offer for JST teams?
Typical overlap is adjustable within JST business hours (roughly 9 AM – 3 PM JST). Weekly check-ins and urgent reviews are scheduled in this window; everything else runs async via Slack or Linear.
Are you familiar with the APAC tech ecosystem?
Yes. I have collaborated on multiple projects with teams across APAC, from startups to enterprises. I can also navigate region-specific compliance requirements and market nuances.
What engagement models are available for Web Development in Tokyo?
Tokyo teams can choose the same flexible models as everyone else: fractional (2-3 days/week), project-based sprints (4-8 weeks), or a monthly advisory retainer. All engagements start with a one-week paid trial.
