How I Built a Full-Stack AI Job Board with Next.js 14, Supabase and Stripe

I just finished building and launching AI Talent Hub — a complete,
production-ready AI & Machine Learning job board. Here's exactly
how I built it, what I learned, and the challenges I faced.

Why I Built This

The AI job market is exploding. Companies are hiring ML engineers,
data scientists, NLP researchers and AI product managers at record
rates. But there was no dedicated, clean job board focused purely
on AI roles.

I decided to build one — and package it as a template for other
developers to launch their own niche job boards.

What I Built

A full-stack job board with:

🔐 Employer authentication (signup/login)
📋 Job posting with Stripe payments
💰 3 pricing tiers (Standard, Featured, Premium)
🗄️ Supabase database for jobs and employers
📊 Employer dashboard to manage listings
🔍 Job search and filters
📱 Mobile responsive design
⚡ Deployed on Vercel

Tech Stack

Technology	Purpose
Next.js 14	Frontend + API routes
TypeScript	Type safety
Tailwind CSS	Styling
Supabase	Database + Auth
Stripe	Payments
Framer Motion	Animations
Vercel	Deployment

Architecture Overview

The app uses Next.js 14 App Router with a mix of server and
client components.

Server Components handle:

Fetching job listings from Supabase
Dashboard data (employer's jobs)
Static pages (about, pricing)

Client Components handle:

Authentication forms
Job search filters
Navbar with auth state

The Payment Flow

This was the most interesting part to build. Here's how it works:

Employer fills out job posting form
Job data is stored in localStorage temporarily
User is redirected to Stripe Checkout
After payment, Stripe fires a webhook
Webhook receives job data from Stripe metadata
Job is inserted into Supabase database
Job appears on the board instantly

// Stripe webhook handler
if (event.type === 'checkout.session.completed') {
  const session = event.data.object;
  const { planId, employerEmail, jobData } = session.metadata;

  const parsedJobData = JSON.parse(jobData);

  await supabase.from('jobs').insert({
    title: parsedJobData.title,
    company: parsedJobData.company,
    is_featured: planId === 'featured' || planId === 'premium',
    employer_email: employerEmail,
    posted_at: new Date().toISOString(),
  });
}

The Hardest Challenge — Supabase Auth on Vercel

This took me the longest to figure out. The issue was that
@supabase/ssr uses cookies() from Next.js, which behaves
differently in server components vs client components.

The fix was using createBrowserClient for client-side auth
and createServerClient with proper cookie handling for
server-side auth.

// Browser client (client components)
import { createBrowserClient } from '@supabase/ssr'

export function createClient() {
  return createBrowserClient(
    process.env.NEXT_PUBLIC_SUPABASE_URL!,
    process.env.NEXT_PUBLIC_SUPABASE_ANON_KEY!
  )
}

// Server client (server components)
import { createServerClient } from '@supabase/ssr'
import { cookies } from 'next/headers'

export function createClient() {
  const cookieStore = cookies()
  return createServerClient(
    process.env.NEXT_PUBLIC_SUPABASE_URL!,
    process.env.NEXT_PUBLIC_SUPABASE_ANON_KEY!,
    {
      cookies: {
        getAll() {
          return cookieStore.getAll()
        },
        setAll(cookiesToSet) {
          cookiesToSet.forEach(({ name, value, options }) =>
            cookieStore.set(name, value, options)
          )
        },
      },
    }
  )
}

Lessons Learned

1. Next.js 14 App Router is powerful but tricky
The distinction between server and client components takes
getting used to. Any component using browser APIs must be
marked 'use client'.

2. Stripe webhooks need careful setup
Make sure your webhook secret is updated every time you
change the endpoint URL. Test with Stripe CLI locally.

3. Supabase RLS policies matter
Don't forget to add Row Level Security policies for every
table. Without them, inserts will silently fail.

4. Deploy early, debug on production
Some issues only appear in production. Deploy to Vercel
early and test there — don't wait until the end.

Database Schema

-- Employers table
create table employers (
  id uuid primary key default gen_random_uuid(),
  email text unique not null,
  company_name text not null,
  created_at timestamp default now()
);

-- Jobs table
create table jobs (
  id uuid primary key default gen_random_uuid(),
  title text not null,
  company text not null,
  location text not null,
  type text not null,
  category text not null,
  description text not null,
  salary text,
  is_featured boolean default false,
  employer_email text,
  posted_at timestamp default now()
);

Results

The template is now live and available for other developers
to use to launch their own niche job boards.

What's Next

Add job application functionality
Email notifications for employers
Analytics dashboard
Multiple job board niches (crypto, web3, remote only)

Conclusion

Building this taught me a ton about Next.js 14, Supabase SSR
auth, and Stripe webhook flows. The biggest takeaway is to
test on production early — many issues only show up there.
