Javascript (React.js, Vue.js, and Next.js) Web App DevelopmentneWwave Studio
I design and ship production-grade web apps that are fast, secure, and easy to evolve. My core stack is React and Next.js with TypeScript, tuned for performance, accessibility, and clean DX.
Core capabilities
Next.js App Router, Server Components, SSR, ISR, edge rendering on Vercel
Strong typing end to end with TypeScript, Zod, tRPC or GraphQL
Data layer with Postgres and Prisma, or Firebase and Supabase when speed matters
Real time via WebSockets, SSE, or GraphQL subscriptions
Payments, auth, and subscriptions with Stripe, OAuth, Clerk, or Firebase Auth
AI features using OpenAI for search, content generation, and recommendations
Design system with Tailwind, Radix UI, and accessible components meeting WCAG 2.2 AA
Quality and velocity
Core Web Vitals and Lighthouse 90 plus targets
CI, preview environments, and automated checks with GitHub Actions
Testing with Playwright, Vitest, React Testing Library
Observability with Sentry, Logtail, and PostHog or GA4
Integrations
CMS, Sanity or Contentful for editorial control
Storage and media with S3, Cloudflare R2, or Supabase Storage
Email, Resend or Postmark, and background jobs with Inngest or Queue workers
How I deliver
Align on outcomes, KPIs, and critical user journeys.
Define data models, API contracts, and roles and permissions.
Ship an MVP slice in 7 to 10 days, iterate in tight cycles.
Harden, measure, and scale with caching, queues, and CDN strategy.
FAQs
Next.js for anything SEO-sensitive or dynamic at scale (SSR/ISR, edge caching). Pure React only for embedded widgets or purely client-side apps. I’ll advise per route and mix as needed.
We set a performance budget on day one, enforce Web Vitals in CI, optimize images/fonts, split bundles, cache aggressively (SWR/React Query + HTTP/CDN), and use ISR/edge rendering where it wins.
OWASP ASVS-aligned checklists, strict CSP/security headers, input/output validation (Zod), auth best practices (HTTP-only cookies/OAuth/OpenID), secrets rotation, and audit logs. GDPR/CCPA supported via data export/delete flows.
Yes. I work contract-first (OpenAPI/GraphQL SDL), create typed clients, add contract tests, and handle auth schemes (JWT, OAuth, API keys). CMS options: Headless (Strapi, Contentful, Sanity), Firebase/Supabase, or your stack.
Stateless services on serverless/edge where suitable, ISR for high-read traffic, queues for heavy writes, CDN for assets, and connection pooling. We design for horizontal scale from day one.
