Technical Diagnostic
A focused review of affected routes, templates, deployment behaviour, crawl signals, CMS behaviour, performance bottlenecks, or code paths, followed by a prioritised fix plan the team can take into delivery.
One shared codebase may serve many tenants, but the real risk is unclear routing, configuration, content, or ownership boundaries as the platform grows.
Make tenant routing, configuration, content ownership, and shared delivery rules explicit before a single Next.js codebase becomes too coupled to scale safely.
A multi‑tenant Next.js platform becomes hard to change when tenant resolution, routing, configuration, content, and ownership boundaries stay implicit. Every new tenant then adds more hidden coupling. The practical move is to separate global from tenant‑specific responsibilities and make the shared architecture clear enough for teams to govern as the platform grows.

Ongoing senior technical cover for architecture, roadmap, supplier review, delivery risk, hiring shape, and platform‑ownership decisions when the team is not ready to hire permanently.
Make shared and brand‑specific responsibilities explicit before reuse creates friction, duplication, governance problems, or avoidable release risk.
Untangle App Router caching and mutation issues when data is not updating, pages feel stale, or behaviour changes unexpectedly between routes.
Review Next.js architecture when tenancy, shared systems, App Router behaviour, or unclear team ownership is making the product harder to change safely.
Senior Next.js architecture work for legacy platforms, difficult migrations, and live stacks that need clearer delivery direction before more work piles on.
Senior technical judgement for teams that need CTO‑style direction, architecture clarity, delivery‑risk reduction, and platform ownership support before hiring permanently.
Principal‑level engineering support when architecture, delivery quality, and technical judgement need strengthening inside the work, not just from the sidelines.

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

Caching strategies for data fetching in Next.js, including force‑cache, revalidation, stale data trade‑offs, and the debugging traps teams hit in production.
