How this works

One AI-native engineer.
The output of a team.

One senior engineer plus AI agents now ships react & next.js engineering that used to need a four-person team. Same code quality, half the cost, three-week timelines instead of three months. Built for pre-seed to Series A founders in Los Angeles who need to ship before the next round closes.

The local read

Why react & next.js engineering is hard in Los Angeles

LA's funded-startup count is larger than Tel Aviv's and Austin's combined, but the engineer-per-startup ratio is the worst on the West Coast. 70+ day hiring cycles. Local agencies are mostly creative-tech shops — great at brand work, slow at shipping infrastructure.

We do the infrastructure. One senior engineer owns your build, Pacific Time, overlap with both your in-house team and your East Coast investors. ComfyUI, Replicate, Runway for media-tech. Next.js + Postgres for everything else. Flat-price quote in 24 hours. Code yours from commit one.

Hiring one senior engineer here is a ~$310K year-one outlay and a 60–90 day search. Our react & next.js engineering engagement starts at $6,000 with a first deploy in 2–4 weeks.

Common questions about react & next.js engineering
in Los Angeles

How fast can you start?

Most builds begin within seven days of the first call. We don't sell discovery — we go from problem statement to first deploy on the same day-one timeline.

Is the price really flat?

Yes. After a 30-minute call we send a single number and a scope you can accept or reject. No hourly billing, no change-order games. If we underestimate, we eat it.

Pages Router or App Router?

Default to App Router for new builds — server components, streaming, Cache Components, and the routing primitives are where Vercel and the framework are investing. We migrate Pages → App on request.

Can you work with our existing backend?

Yes — REST, GraphQL, gRPC, your homegrown JSON-RPC. We wrap it in a typed client and the frontend doesn't care about the protocol underneath.

Who owns the code?

You do, from commit one. The repository is created in your GitHub org. Infrastructure is provisioned in your cloud account. We don't host your stack on ours and we don't lock you in.
