How we vet
Five stages before anyone touches your code.
Portfolio and code review
We read real Next.js code before we talk: routing structure, data fetching choices, and how the candidate splits server and client work.
Technical interview
A senior engineer covers rendering strategies, caching, Server Components, and TypeScript. No trivia, only what production work demands.
Paired build exercise
The candidate builds a real route against a real API with one of our engineers watching how they think, not just what they type.
Communication check
Written and spoken English, async updates, and how they explain a rendering decision to a non-technical founder.
Supervised first sprint
Every new engineer's first two weeks run under senior review. Every PR gets a second set of eyes before it reaches your branch.
Why us
What you get with WitsCode that a staffing bench can't give you.
Your hours, not ours
Our working day is built around overlap with US and UK business hours. Standups, reviews, and launch calls happen when you are awake, and blockers get cleared the same day you raise them.
An engineering studio, not a bench
You are not renting an idle contractor from a staffing list. Every Next.js engineer works inside the delivery system we built across 300+ launches: code review, preview deployments, and QA gates that do not depend on any one person.
Senior skill, sensible cost
We are based in India, so a senior Next.js engineer costs a fraction of an equivalent US or UK hire. The saving comes from geography, not from cutting seniority, process, or code quality.
Frequently asked
Questions before you reach out.
Most Next.js engagements start within three to five business days of a signed agreement, because we match you with an engineer already vetted through our five-stage pipeline rather than opening a fresh recruitment cycle. You brief us on the stack and the backlog, interview the profile we propose, and work begins the same week.
Next.js adds server rendering, file-based routing, image optimization, and API routes on top of React, which means faster first loads and pages search engines can actually read. For marketing sites, funnels, and most SaaS products that is the difference between ranking and not. We still recommend plain React where a fully private app never needs SEO.
Yes, performance and search readiness are checked on every engagement rather than treated as a separate project. That covers rendering strategy, image and font loading, caching, metadata, and structured data. Changes are measured against Core Web Vitals before and after, so improvements trace to real numbers instead of claims.
Yes, migrations from plain React, older frameworks, and CMS-driven sites are a regular part of the work. We map routes and redirects first so search rankings survive the move, rebuild page by page on preview deployments, and cut over only after the new build passes QA. Traffic keeps flowing throughout.
Yes, every engagement includes a guaranteed overlap window with US and UK business hours, which is when standups, demos, and pairing sessions happen. Deep focus work runs in the remaining hours, so you often wake up to finished tickets. You agree the exact window before the engagement starts and it stays fixed.
We replace the engineer at no extra cost and manage the handover ourselves, usually within one week. Because every developer works inside our shared standards and review process, a replacement picks up the codebase quickly instead of starting from zero. You will not repeat onboarding or lose sprint momentum.
