Summary
FAQs
React or Next.js—what do you recommend?
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.
How do you ensure performance?
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.
What about security and compliance?
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.
Can you integrate with our existing APIs/CMS/DB?
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.
How do you handle scalability?
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.
