Full stack development

Full Stack Development for Web Products and SaaS

We build the interface, server, database and integrations as one product. Curiosive works with founders launching a first release and teams extending an application already in production.

A useful scope starts with a customer workflow, the data it touches and the acceptance criteria that prove it works. We can deliver a bounded build or join your team as an ongoing engineering partner.

From interface to production

Full stack work covers the product screens, API contracts, database model, permissions and deployment. We use TypeScript, React and Next.js where they fit, with server and database choices made around the product rather than a fixed template. Integrations, administrative tools and handover belong in the delivery scope.

New products and existing codebases

For a new product, we scope the smallest usable release and define what is outside it. For an existing application, we first read its architecture and identify the boundaries affected by the change. AI assists implementation; engineers review authentication, permissions, data changes and the code that reaches production.

Scope and engagement

Work runs as AI-accelerated development, starting from $2,000 per month. After discovery we agree the scope, capacity, deliverables and acceptance criteria in writing, then work through one prioritized queue with senior review on every change. The engagement renews monthly and can be adjusted as the roadmap changes.

How it starts

What happens after you write to us.

  1. 01

    You describe the product

    One paragraph on what you are building, roughly when you need it, and who it is for. No brief, no form with fifteen fields.

  2. 02

    You get a reply within a day

    From the engineer who would do the work, not a sales team. If we are not the right fit we say so, and where possible we point you somewhere better.

  3. 03

    You get a scoped plan

    Scope, price and timeline in writing before anything is committed. You decide with the numbers in front of you.

No long contract to begin, no lock-in to our tooling, and the code is yours from the first commit.
