I Built a Free AI Tool 🤖 That Tells Indian Developers EXACTLY What They're Worth in the Market 💰

Raj Kumar — Mon, 18 May 2026 06:18:11 +0000

Most Indian developers have no idea what their profile actually signals to the market.

Not your resume. Not your GitHub.
Your signal.

I built something to fix that — and I want to show you exactly how it works. 👇

I'm a React and full-stack developer — Node, Express, the works.

And at some point I realised: I had skills. But I had no visibility into how those skills were valued, how they matched to real jobs, or where I was falling behind the market.

So I built Kareevo — an AI Career Intelligence Platform, made for Indian professionals.

Solo. Free-tier tools. Nights and weekends. 🛠️

And now it's live — and it's 100% free. Forever. No paywall. No credit card.

⭐ 100% Free · No plans · No credit card · No paywalls

Here's the first thing you see when you log in 👇

Your Career Health Score — a real number out of 100, based on live market data.

Not vibes. Not guesswork.
Skills relevance. Experience value. Market demand. Salary position. All scored. All visible.

It even tells you your rising skills — TypeScript, GraphQL, Next.js — so you're not learning the wrong things. 🎯

This one hits different. 👇

Kareevo shows you exactly what the Indian market pays for your role, your experience, your city.

Market range for full-stack (4 yrs): ₹8–15 LPA
Top city: Bangalore ₹14L
Tamil Nadu benchmark: ₹11L

If you've ever gone into a salary negotiation with no data — this is the tool you didn't have. 💰

No more "maybe I'm 60% qualified for this." 👇

Kareevo matches you to jobs based on your actual profile — not just your title.

It shows your match %, which skills got you there, and the exact one skill standing between you and 100% match.

That's not a job board. That's intelligence. 🔍

Your Skill Radar scores every skill against live market demand.

React: 85. Hot. Git: 100. Stable. And if a skill is going obsolete? Kareevo warns you before it hurts your score. 🚨

Most platforms spam you daily. Kareevo doesn't.

Every email is triggered by a real signal — a new job match, a skill warning, your Monday career report.

No match today? We stay silent. That's the promise. 🤫

What you get:
⭐ Career Health Score — real-time from live market data
💰 Salary Intelligence — your exact market value in ₹ LPA
🎯 Job Match Alerts — only jobs that fit your profile
🚨 Skill Gap Warnings — before they hurt you
📊 Weekly AI Reports — your career brief every Monday
📧 Email Intelligence — signal-only, no spam

I built Kareevo as a solo developer — React, Node, Express, and mostly free-tier tools stitched together with late nights.

No big team. No funding. Just a problem I felt personally and decided to solve.

It's not perfect. I'm still learning, still shipping, still improving.

But it's live. It works. And it's completely free — because every developer deserves to know where they actually stand. 🙏

Try Kareevo — it takes 2 minutes 👇

If you're a developer, fresher, or mid-level professional — go check your score.

Then come back and tell me 👇
What was your Career Health Score? Did the salary gap surprise you?

Introducing react-number-rating – A 1–10 React Rating Component for Better UI

Raj Kumar — Fri, 18 Jul 2025 08:32:56 +0000

🔥 Introduction

“The react-number-rating component helps you add clean, user-friendly numeric rating systems (1–10) in React apps with minimal setup.”

If you're building a feedback form, product rating, or any kind of review system in a React app, you’ve probably used stars, sliders, or emojis. But what if you want something more precise, clean, and customizable?

Introducing react-number-rating — a modern and developer-friendly rating component for React that displays a numeric scale from 1 to 10, with optional color coding to visually represent the score strength.

🔗 Live Demo

👉 Try it on CodeSandbox

✨ Features

✅ Numeric scale from 1 to 10
✅ Custom color for each number
✅ Easily style via props or CSS
✅ Lightweight – no external styling libraries
✅ Built with React 17/18 compatibility
✅ Perfect for feedback forms, review UIs, or product ratings

      value={priority}
      name="priority"
