Your LA SaaS App is Still on Rails. You're Losing Customers to Load Time.

If you're a LA founder watching Vercel teams ship in days while your agency bills quarters, you've found your rebuild partner.

We build production-grade Next.js applications for Los Angeles startups and enterprises. App Router, Server Components, Supabase, Vercel -- shipped fast.

Next.js Application Development

Next.js application development is the practice of building full-stack web applications using React Server Components, the App Router, and streaming SSR on Vercel's edge network. For SaaS and DTC products, this means sub-second page loads, server-rendered data fetching without client waterfalls, and a deployment pipeline that ships features daily. We scope, architect, and deliver these applications end-to-end, including database design on Supabase and compliance-ready schema structures for California-based products.

What is holding your current website back?

Common gaps we find in nearly every audit.

Your Rails or legacy app takes 3-6 seconds to load on mobile, and your analytics show a direct correlation between that delay and checkout or signup abandonment.
Risk: Every 100ms of additional load time compounds into lost trial conversions, lower Google Core Web Vitals scores, and reduced organic ranking in a competitive LA market.
Your current agency or in-house team operates on quarterly release cycles, meaning competitor features ship while your roadmap items sit in a backlog waiting for the next sprint review.
Risk: SaaS founders in slow-deploy cycles lose product-market fit windows. By the time a feature ships, the customer need or competitive landscape has shifted.
Your application was not built with CCPA in mind, and your user data schema mixes PII into tables that have no deletion or opt-out pathway.
Risk: California law requires a verifiable consumer request process. Without schema-level data segregation, a single compliance audit or user complaint becomes an engineering emergency.

How We Build This Right

Every safeguard, built in from Day 1.

CCPA-Ready Data Schemas

We design Supabase schemas with PII isolation from day one, including row-level security policies and deletion pathways that satisfy California Consumer Privacy Act verifiable request requirements.

Core Web Vitals Accountability

Every delivery milestone includes Lighthouse and CrUX field data benchmarks. We do not hand off a build that fails INP, LCP, or CLS thresholds against your production URL.

Vercel Access Controls and Audit Logs

Production environments are provisioned with team-scoped access, environment variable encryption, and deployment protection rules so your codebase meets basic SOC 2 access hygiene before you pursue formal certification.

What We Build

Purpose-built features for your industry.

App Router and Server Components

We migrate or build from scratch using Next.js App Router with React Server Components, eliminating client-side data waterfalls and reducing JavaScript bundle size shipped to the browser. The result is faster Time to First Byte and a simpler component architecture your internal team can maintain.

Streaming SSR with Suspense Boundaries

Slow data dependencies no longer block the entire page render. We implement Suspense boundaries so the shell and static content stream immediately while database-dependent sections resolve in parallel, measurably improving perceived load time for users on mobile networks.

Supabase Backend Architecture

We design Postgres schemas on Supabase with row-level security, edge functions for low-latency API routes, and real-time subscriptions where your product requires live data. Auth, storage, and database are provisioned in a single auditable project linked to your Vercel deployment.

CI/CD Pipeline and Preview Environments

Every pull request gets a Vercel preview deployment with its own environment variables and database branch. QA, stakeholder review, and regression testing happen before code reaches production, cutting the feedback loop between design, engineering, and your product team.

Our Development Process

From discovery to launch. Quality at every step.

01

Technical Discovery and Architecture Scoping

1 week

We audit your existing stack, identify the specific bottlenecks in your current app — slow queries, client waterfalls, monolithic bundles — and produce a written architecture proposal with App Router structure, data model decisions, and a phased delivery plan.

02

Foundation Build and Data Migration

2 weeks

We establish the Next.js project structure, configure Supabase with RLS policies and CCPA-compliant schema design, set up the Vercel project with environment controls, and migrate or remodel your existing data layer. No features yet — the foundation has to be correct.

03

Feature Development with Weekly Deployments

2-4 weeks

Core product features are built in prioritized order with preview deployments each week. You review working software against your production URL, not mockups. Feedback is incorporated in the following sprint cycle with no change order overhead for scope that was already discussed.

04

Performance Audit, Handoff, and Documentation

1 week

Before final delivery we run a full Core Web Vitals audit against field data, resolve any threshold failures, and produce written documentation covering your schema, environment setup, and deployment process so your team can ship independently on day one after handoff.

Frequently Asked Questions

Being in LA actually matters here. In-person sprint reviews, Pacific Time communication, no timezone friction when you're coordinating with design and marketing teams. We also know the California market -- Silicon Beach, CCPA, the whole thing.
LA Next.js projects run from $8K for marketing sites to $60K+ for full SaaS platforms with Supabase, auth, and dashboards. Enterprise builds with AI features start around $75K. Everything is fixed-fee after a scope audit -- you know the total before you sign anything. No hourly billing surprises.
App Router has nested layouts, parallel routes, intercepting routes, and React Server Components built in. Complex SaaS navigation renders faster with less JavaScript. Pages Router still works fine, but App Router is the default in Next.js 15 and it's where the framework is headed -- new projects should start there.
Supabase runs on PostgreSQL. You get row-level security, full SQL access, and no vendor lock-in. Firebase's proprietary NoSQL database gets expensive at scale and struggles with complex queries. Supabase includes edge functions, realtime, and auth -- all open-source. If you outgrow the managed service, you can self-host.
Server Components send HTML. No JavaScript bundle for those components ever reaches the browser. A product listing page that used to ship 400KB of React code now ships 50KB. Content loads faster, Google indexes it immediately, and Lighthouse scores jump 20-30 points without changing anything visual.
Yes. Data deletion endpoints, consent management UI, and audit logging go into the Supabase schema from the start. CCPA requires that users can request data export and deletion -- we build those API routes into the core application, not as an afterthought six months before an audit.
