Technical Diagnostic
A focused review to establish what is happening, where the risk sits, and what should happen next, ending with a prioritised plan the team can take into delivery.
This is for platforms that have outgrown informal boundaries and now need clearer decisions about ownership, shared responsibilities, deployment, and how teams work across the estate.
Define Next.js platform boundaries when domains, routes, tenants, brands, content ownership, data ownership, deployment models, or team responsibilities are making change unsafe.
Complex Next.js platforms fail when architecture decisions stay implicit. Centralisation, multi‑tenancy, App Router adoption, or a design system may be useful, but none is automatically the right answer. I map the domain model, route ownership, content, and data boundaries, deployment model, shared components, runtime assumptions, and team responsibilities before recommending the smallest platform model the organisation can actually govern.
I help CTOs and product leaders keep delivery capacity and platform stability in view when shared routes, tenants, brands, content models, or App Router behaviour are becoming hard to govern.
Choose the architecture question that is closest to the current platform shape.
A focused review to establish what is happening, where the risk sits, and what should happen next, ending with a prioritised plan the team can take into delivery.
Senior hands‑on support inside an existing team when architecture, implementation, review, and delivery decisions need to stay connected.
Ongoing senior technical direction when a team needs stronger leadership and platform ownership before a permanent hire makes sense.
Make tenant routing, configuration, content ownership, and shared delivery rules explicit before a single Next.js codebase becomes too coupled to scale safely.
Make shared and brand‑specific responsibilities explicit before reuse creates friction, duplication, governance problems, or avoidable release risk.
Untangle App Router caching, stale data, RSC boundaries, mutation paths, and invalidation problems when production behaviour no longer matches the team's expectations.
Senior platform assessment and technical direction for React and Next.js estates where routing, CMS, deployment, SEO, ownership, and delivery risk have become one problem.
Senior technical direction for organisations that need CTO‑style judgement across roadmap, suppliers, architecture, and release risk before a permanent leadership hire makes sense.
Principal‑level support inside active delivery when architecture, standards, mentoring, documentation, ownership transfer, and implementation decisions need strengthening whilst the team keeps shipping.
Headless architecture advice before CMS, content model, preview, revalidation, metadata, schema, media, localisation, and editorial ownership decisions become expensive to reverse.

How to design multi‑tenant Next.js architecture across routing, domains, configuration, content, caching, previews, analytics, and team ownership.

Multi‑tenant applications serve multiple customers from a single codebase. Here, I walk through building a scalable multi‑tenant web application using Next.js.

Next.js vs. Remix compared properly, across routing, data loading, mutations, caching, and the architectural trade‑offs teams actually feel in production.

Next.js Proxy replaces Middleware in v16. See what changed, how to migrate to proxy.ts, and when request‑time interception still belongs in production.

A Pages Router to App Router migration checklist for Next.js teams, covering routing, data fetching, caching, metadata, server components, and rollout.

Next.js gives us two ways to handle back‑end logic: API Routes and Server Actions. Here, I clearly explain when to choose each approach for the best results.
