SoulSync is a next-generation compatibility and personalization platform built around hyper-dimensional digital twins.
We map individuals across psychological, cognitive, emotional, behavioral, and lifestyle dimensions to generate deep, adaptive profiles that evolve over time. These profiles power smarter matching, personalization, and insight—far beyond surface-level preferences or static questionnaires.
SoulSync blends systems thinking, behavioral science, and modern software architecture to create meaningful human alignment at scale. The product is designed for real-world use cases where understanding people deeply creates leverage.
This project includes full-stack platform development, data modeling, and AI-driven profiling infrastructure, with a focus on scalability, privacy, and long-term adaptability.
Appreciate it!

React, TypeScript, Node.js, Express, tRPC, PostgreSQL, Prisma, Socket.IO, Yjs, Gemini, pgvector
A developer-focused platform combining real-time messaging, collaborative code editing, persistent sessions, and AI-powered semantic search over private conversations.
Key features
1) Real-time one-to-one chat and syntax-highlighted code sharing.
2) Concurrent collaborative editing using Yjs CRDTs and WebSockets.
3) Persistent code sessions with database-backed state recovery.
4) RAG-based semantic search using Gemini embeddings, PostgreSQL pgvector and HNSW indexing.
5) Answers grounded in relevant messages with citations.
6) 71 manually written server-side tests.
What was the trickiest part of getting Yjs and the saved sessions to work together? I'm curious how you handled someone reconnecting after others had kept editing.

It screens incoming mail, surfaces what needs a reply, holds the rest. Gmail and Outlook. A dollar for three days then ten a month.

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
