Why teams pick this engagement
What you get out of it
- Faster Core Web Vitals — INP, LCP, CLS in the green from launch
- Typed end-to-end so refactors are safe and onboarding is fast
- Auth, RBAC, billing, and observability wired in from day one
- Per-PR preview environments and deploys under 10 minutes
Overview
What this service is
We build the kind of web platforms a CTO is happy to inherit: typed end-to-end, observable, performant, and aligned with the way modern teams actually ship.
Deliverables
Production Next.js app
App Router, RSC, Edge runtime where it matters.
Auth, RBAC, billing
Battle-tested patterns for SaaS-grade access control.
Design system
Tailwind + Radix + shadcn primitives, fully tokenized.
CI/CD + preview envs
Per-PR previews, automated tests, zero-touch deploys.
Observability stack
Logs, traces, error tracking, web vitals.
How it runs
Four phases. Production from day one.
Architect
Map domain, data model, auth, and edge boundaries.
Build
Two-week sprints, demos every Friday, production from day one.
Harden
Load testing, accessibility, security, observability.
Hand off
Docs, runbooks, on-call rotation if you want it.

FAQ
Web Platforms — common questions
- Next.js gives us streaming SSR, React Server Components, file-based routing, and a deployment model that just works on Vercel and most cloud providers. For most product platforms it removes a year of plumbing work and gives us better Core Web Vitals out of the box than a custom React setup.
- Most platforms ship the first production release in 6–10 weeks, with a 12–14 week window for larger systems with billing, RBAC, and admin tooling. We work in two-week sprints with a demo every Friday, so you see real software inside the first 14 days.
- Yes. The handoff is a feature, not an afterthought. You receive runbooks, architecture decision records, an on-call rotation if you want one, and a code review channel where your engineers can ask questions for 30–60 days post-launch.
- Often, yes. We ship most often in TypeScript with Next.js or Remix, but our principal engineers also work in Node, Go, and Python. If your stack is in good shape, the right move is usually to extend it — not rewrite it.
