EasyCV.ai: a CV SaaS with an AI co-pilot, from zero to paying subscribers

A complete product I designed, built and launched alone: the editor, the templates, the AI, the billing, the content and the infrastructure. It runs every day with customers who pay.

The problem

Three CVs out of four are rejected by screening software before a human reads them. Candidates do not know why, and existing tools only offer pretty templates. EasyCV had to do better: say what blocks, fix it, and tailor the CV to the target job.

What I built

  • A CV editor with 32 PDF templates, rendered server-side so the downloaded PDF matches the preview exactly.
  • An AI co-pilot: section rewriting, ATS score with reasons, tailoring to a pasted job offer, custom sections created by the assistant. Fourteen AI endpoints, each billed in credits per use, charged on commit rather than on trial.
  • A job board on the France Travail API, and an embeddable widget for B2B partners.
  • Stripe subscriptions and payments, Brevo transactional e-mails, a 64-article blog in five languages generated and maintained by a content pipeline.
  • An admin dashboard, six scheduled jobs, and per-user AI cost tracking.

How it is built

Next.js 15 with the App Router and TypeScript, Supabase for database and auth, Tailwind and shadcn/ui for the interface. Docker deployment on Hetzner through Coolify and Traefik, driven by GitHub Actions. The AI models are interchangeable: prompts are versioned, evaluated, and the cost per request is measured before a feature opens to customers.

One thing that matters to a client: when a subscriber reported that the co-pilot created invisible sections, the issue was isolated, fixed across all 32 templates, and production data repaired the same day, with no downtime.

What it shows

That a complete product, with billed AI and paying customers, can be designed, built and run by one person who masters the whole chain. It is the same craft I apply to your projects: from scoping to production, then on to maintenance.

What you can hold me to

Simple terms, on everything I build

Price first written and signed before the first line of code
A working demo before we talk about the full budget
You own it the code, the domain, the accounts, the documentation
I stay after launch, watching and improving

Questions

What people ask about this project

Can you build a SaaS like this for me?

Yes. It is the project shape I know best: a first production version in two to three months, then regular releases. The price is written before we start and you own the code.

How do you keep AI costs under control?

Every call is measured and billed to the user in credits, prompts are versioned, and features open only after evaluation on real cases. You know the cost per use before launch.

Tell me what you want to build

Twenty minutes, no obligation. Describe the need in your own words; I will tell you honestly whether I can build it, how long it takes and what it costs. If I am not the right person, I will say so.
