A full-stack portfolio for products you built end to end

Full-stack developers are hired for range: you designed the schema, built the API, shipped the UI and deployed it. FNJ's AI builder designs a portfolio that shows that range per project, from interface to infrastructure, with live demos and repos one click away. Export it as Next.js and it becomes one more thing you shipped.

Sample site with fictional names, made to show the kind of site the builder designs. Yours is designed from your description and the reference you choose.

The same sample at phone width. The builder designs every page at desktop, tablet and phone widths.

The sample, section by section

What a full-stack developer website needs

The sections the builder can design for you, and the job each one does. The starter prompt asks for these; add or drop any of them in your own words.

  1. 01

    Intro

    The kind of products you build end to end.

  2. 02

    Products

    Cards with a screenshot, stack and links.

  3. 03

    Project pages

    UI, API, data and deployment, one block each.

  4. 04

    Stack

    Front end, back end, data, infrastructure.

  5. 05

    Experience

    Roles and products shipped.

  6. 06

    Contact

    Email and profiles.

Made for full-stack developers, not for everyone

Starter prompt

A prompt written for full-stack developers

It opens in the builder ready to edit. Replace the words in brackets with your own details, change anything else you like, then add a reference.

Reference to add

A developer's portfolio or SaaS homepage with a clean, technical feel you like.

The builder takes a reference's look (layout, type, palette, spacing), never its words or images.

Use this prompt
Build a full-stack developer portfolio for [your name], who builds web products with [React, Node.js and PostgreSQL]. Open with a confident introduction. Add a 'Products' section with four project cards (screenshot, one-line description, stack tags, live demo and GitHub buttons) and a page per project broken into four blocks: interface, API, data model and deployment. Add a stack section grouped into front end, back end, data and infrastructure, an experience section and a contact section. Modern and technical: a clean sans-serif, monospace labels, a dark interface with one bright accent.

How it works

  1. 01

    Describe your full-stack developer site

    Open the builder with the starter prompt, fill in your details and add a screenshot or link of a site you'd like yours to look like. A reference is required: it's what makes the design yours rather than a template.

  2. 02

    Watch it design every page

    The builder plans the pages, palette and type, then builds each page section by section on a canvas at desktop, tablet and phone widths while you watch.

  3. 03

    Refine it, then take the code

    Ask for changes in plain words or edit by hand, upload your own screenshots, then download a Next.js project or static HTML, or push it to your GitHub, and host it where you like.

What it costs: From $25/month, or $29 once for 50 credits that never expire. No FNJ hosting fee: you host the exported site. See plans

Full-stack developers: questions

Can my portfolio show live demos?
It links to them: each project card gets a live demo button pointing wherever your demo runs. The portfolio itself is a static site.
Can I add a contact form backed by my own API?
The builder doesn't create forms, but the exported Next.js project is yours: add a form and an API route there.
Will the export fit into my usual deploy pipeline?
It's a standard Next.js project (or static HTML), so it deploys on Vercel, Netlify, Cloudflare Pages or a container like any other.
How many projects can I include?
As many as fit your plan's page limit if each gets its own page: up to 10 pages per site on the Site Pack and 20 on subscriptions.
