Development of a self-hosted SaaS module (MVP)

Hello!
1. I don't have similar projects, but I have experience in creating MVPs from scratch using Next.js (React) + Nest.js (Node.js) for various needs. I can provide examples in private.
2. I have experience working with Puppeteer, specifically writing scripts for fraud.
3. To be honest, I don't fully understand the technical specifications, so I can't assess the entire project right now — we can discuss this in more detail.
4. Yes.

The deadline and cost are indicated approximately, based on what I understood from the task.

We are the Netly agency, specializing in the development of custom web applications and SaaS solutions. Our team has experience in creating complex backend services (FastAPI, Flask) and frontends in React with TailwindCSS, which allows us to quickly adapt to your stack of Node.js + Fastify and React. We have worked on Webhook integrations, auto-login through headless browsers (Puppeteer, Playwright), and implemented billing systems on cryptocurrency gateways, so your requirements for lead generation, contact validation, and SaaS licensing are familiar to us. We are ready to develop an MVP, prepare docker-compose, documentation, and a basic admin panel, as well as support the further development of the product. We offer an hourly rate of $10/hour or a fixed cost after clarifying the scope of work.

Hello.
I have extensive experience building SaaS platforms in the fintech and leadgen space, with a strong focus on Node.js, React, and API/webhook integrations, which aligns directly with your project requirements. My past work includes automation of lead flows from Facebook, TikTok, and Google Ads into CRMs, complete with validation, fingerprint injection, and browser emulation using Puppeteer/Playwright. I understand the unique challenges of your niche — including white-page compatibility, anti-fraud checks, and replay traffic engines — and have successfully solved these in similar gray-vertical solutions. Additionally, I have implemented crypto billing (USDT) with subscription licensing and scalable deployments using Docker on VPS providers like Hetzner. With this background, I am confident I can deliver your MVP quickly, fully documented, and ready for long-term scalability.
Thanks
