A practical breakdown of when Next.js + Sanity is the right stack, what it buys you for SEO and velocity, and the trade-offs to watch.
Production-grade Next.js + Sanity CMS websites for startups and agencies — marketing sites, headless rebuilds, content platforms, internal dashboards, and greenfield MVPs. I've shipped across SaaS, Web3, recruitment, e-commerce, real estate, and education.
A polished marketing site with 6–10 pages and Sanity Studio is usually 3–5 weeks from kickoff to launch. Larger headless rebuilds and product surfaces typically run 6–12 weeks. I share a staging URL from day one so progress is visible every working day.
Yes — most of my work is for US, UK, Ireland, and Middle East clients. I'm based in Surat, India (IST, UTC+5:30) which gives a healthy overlap with EU mornings and US East-coast mornings. Communication is on Slack, Discord, or Notion plus a weekly call.
Next.js (App Router), React, TypeScript, Tailwind CSS, and Sanity CMS for the front of house. Node.js, REST APIs, PostgreSQL/Prisma where backend is needed. Vercel for hosting, Algolia for search, SendGrid for transactional email, GSAP/Framer Motion for interactions.
Every site I ship targets 95+ Lighthouse scores and green Core Web Vitals on key pages. I bake in JSON-LD structured data, Next.js Metadata API for canonicals/OG, automated sitemaps, image optimisation via Sanity CDN, and edge caching from the first commit — not bolted on at the end.
Yes — I've shipped onto projects ranging from solo-founder Sanity sites to platform codebases used by 40+ countries of users. I start with an audit week to map architecture, dependencies, and risk, then ship incrementally. Same deal whether it's a Next.js, Gatsby, or SvelteKit codebase.
Easiest is a 30-minute call via cal.com/nayankyada to scope the work, talk timeline and budget, and decide if we're a fit. After that I send a written proposal with milestones and a fixed price or weekly rate, depending on the shape of the project.
