CENTHINEL: Developer Tools

Hey Product Hunt community! 👋 I'm thrilled to introduce **CENTHINEL** (https://centhinel.sbs) to you all today! 🚀 As an engineer and digital creator, I noticed that most freelancers, founders, and creators in Latin America struggle with two main bottlenecks: 1. **Pricing & Metrics Intuition**: Many independently calculate rates or ad spending blindly, without factoring in non-billable hours, local taxes, or break-even ROAS. 2. **Generic AI Output**: People use LLMs like ChatGPT with basic single-line queries, getting mediocre, cookie-cutter answers instead of business-ready copy and systems. That’s why we built **CENTHINEL** as a lightning-fast, zero-friction interactive hub: ⚡ **Free Interactive Suite**: • **USD Freelance Rate Calculator**: Factoring in real billable hours, taxes, fixed expenses, and safety margins. • **AI Prompt Optimizer**: Built on the RTCF & CO-STAR context-engineering frameworks. • **Break-Even ROAS Calculator**: Find your exact advertising equilibrium point before spending $1 on Meta or TikTok Ads. • **Compound Interest & Runway Simulator**: Financial security planning for remote workers. 🛠️ **Custom Engineering**: We also build custom, ultra-fast web platforms with 99+ PageSpeed scores, 100% proprietary GitHub code delivery, and 1-year free custom domain inclusion. I’d love to get your thoughts, feedback, and suggestions on what calculators or tools we should build next! Thank you so much for your support! 🙌
