I love this
KAUREX.in is my agency operating system - built to deliver landing pages + automation + full-stack marketing without agency chaos.
What is KAUREX?
KAUREX is not a freelancer profile. It's an OS with 8 specialist pods:
Website / Landing Page Pod (WordPress, 48hr delivery)
Automation Pod (GoHighLevel + n8n, WhatsApp routing)
LSA Pod (Google Local Services Ads)
Ads Pod (Google + Meta)
Video Pod (AI + editing, ratio fix, repurposing)
SEO Pod (RE & local)
Content Pod
Support Pod
Why I built it?
Clients hiring on Contra want personal expert, not agency spam. But they also need full stack. So I work as Kaushal Kumar (personal) for Landing Page + Automation - my core. If client needs LSA/Ads/Video/SEO - KAUREX pods deliver white-label under my name.
What this video shows:
This is a free AI-powered web tool inside KAUREX.in - Upload video, prompt "Adjust to 4:3 with padding, do not crop" and AI recreates video without cutting text/faces.
In this demo:
I uploaded a 16:9 portfolio video that Contra was cropping
Prompted for 4:3 with padding
KAUREX tool added brand-color padding (violet #2D1B4E) and kept full content
Output ready for Contra 4:3 cover, no crop
Tech behind KAUREX:
Frontend: WordPress + Elementor + Custom AI interface
Backend: n8n workflows + GoHighLevel CRM + AI video API
Delivery: 48hr landing, 72hr automation, white-label via pods
This project is my second portfolio work - first is my personal showreel, second is KAUREX OS demo. It proves I don't just design - I build systems.

the 4:3 padding tool is a neat fix for the contra cover crop. where do most of your landing page clients come from right now, contra or your own outreach
Atlas is a full-stack ecommerce platform with 3D models and 2D images of products for online shopping and product management.
Features:
• Products, 3D viewer and category management
• Search, filtering, sorting, and pagination
• Product variants and inventory
• Shopping cart and wishlist
• User authentication and accounts
• Address and order management
• Product reviews and notifications
• Admin functionality
• REST API integration
Built with React, TypeScript, Tailwind CSS, Node.js, Express.js, and MySQL.
I’d load the product photo first and fetch the 3D model only when someone opens the viewer, especially on mobile. Does Atlas keep the photo usable while the model loads or if WebGL is unavailable?
