I built a minimalist Sales Pipeline with React + FastAPI (And deployed it to Vercel)

Hey everyone!

I wanted to share a project I've been working on: Salesflow. It's a minimalist sales pipeline designed for people who hate bloated CRMs and want something fast and clean.

The Stack:

Frontend: React + TypeScript + SCSS

Backend: Python (FastAPI)

Deployment: Vercel

I just launched the early live version to test the core value and see if anyone actually needs a tool like this, or if I'm just building for myself again.

Here is the live link: https://salesflow-lemon.vercel.app/

I hooked up a quick waitlist form for early access. I'd love to hear your honest feedback on the UI/UX and the overall idea. What would you add or change?

How to Bypass LinkedIn Commercial Use Limit in 2026 (Without Paying $150/mo)

LinkedIn is aggressively cutting down on free features. If you are a solo founder, indie hacker, or technical recruiter, you've probably hit that depressing screen: "You've reached the commercial use limit on search."

LinkedIn wants you to shell out $150+/month for Premium or Recruiter Lite just to view public profiles.

As a student and independent developer, I couldn't afford that. So I decided to find a workaround using code.
The Solution: Google X-Ray Dorking

Most people forget that Google indexes almost all public LinkedIn profiles. By using advanced search operators (also known as Google Dorking), you can bypass LinkedIn's internal search limits completely.

For example, if you type this directly into Google:
site:linkedin.com/in/ "Senior React Developer" "Italy"
Google will return live LinkedIn profiles without counting towards your monthly limit.
The Problem with Manual Dorking

Writing these strings manually sucks. If you need to find someone with a specific stack (e.g., FastAPI + Next.js + Stripe integration experience), your search query becomes a massive, unreadable monster. One typo, and the search breaks.
Enter GhostIn 👻

To solve this for myself and other bootstrappers, I built GhostIn. It’s a lightweight OSINT tool powered by an AI Strategist.

Instead of messing with complex search syntax, you just describe your hiring goal in plain English (e.g., "I need a Python engineer in Europe who knows AWS"). The AI automatically generates the perfect, optimized Google X-Ray dork and hands you the results instantly.
Zero Friction (No Signup Required)

I initially launched it with a mandatory registration wall, but after looking at the analytics, I realized people just want to solve their problem fast without giving away their emails.

So I removed the signup requirement completely.

You can now run 5 AI-powered searches daily for free and completely anonymously directly on the homepage. No credit cards, no accounts, no bullshit.
