Behind every successful digital product is clean code, a solid backend, secure APIs, and an architecture built to scale.
That's exactly what I deliver.
I help startups, founders, and businesses build high-performance web applications, mobile apps, backend systems, AI-powered solutions, and custom automation that save time and support growth.
You don't need to be a full-stack engineer to build custom digital products, but knowing basic HTML, CSS keyframes, and JavaScript webhooks will give you superpowers in:
𝗪𝗼𝗿𝗱𝗣𝗿𝗲𝘀𝘀: 𝗖𝘂𝘀𝘁𝗼𝗺 𝗖𝗦𝗦,𝗛𝗧𝗠𝗟 & 𝗦𝗵𝗼𝗿𝘁𝗰𝗼𝗱𝗲𝘀
𝗙𝗿𝗮𝗺𝗲𝗿: 𝗙𝗿𝗮𝗺𝗲𝗿 𝗖𝗼𝗱𝗲
𝗪𝗶𝘅: 𝗪𝗶𝘅 𝗖𝗼𝗱𝗲 (𝗩𝗲𝗹𝗼) 𝗮𝗻𝗱
𝗦𝗵𝗼𝗽𝗶𝗳𝘆: 𝗟𝗶𝗾𝘂𝗶𝗱 𝗖𝗼𝗱𝗲.
All allows you to create custom API forms, micro-animations, and tracking pixels that standard builder blocks can't do.
I’m Hammad, Senior Full-Stack Developer & Founder of CodexEngr, helping startups and businesses build scalable SaaS platforms, modern web applications, and AI-powered solutions.
Startups and established businesses usually want pretty different things from a SaaS build. Which side has been the better fit for CodexEngr so far, founders starting from zero or teams adding a product next to an existing business?
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
