Title:
AI Personality Discovery App — SoulPrint
Description:
Built SoulPrint from scratch — a fully functional AI-powered personality discovery web app that maps users to one of 6 soul archetypes through a 10-question quiz.
The app uses GPT-4o mini to generate a unique, personalised result for every user based on their actual answers — including a custom description, motto, trait scores, career insights, relationship style, and shadow analysis. No two results are identical.
Technical work included:
Built the entire frontend as a single optimised HTML file — no frameworks, no dependencies
Integrated OpenAI API securely via Netlify Functions (API key never exposed to browser)
Implemented a weighted scoring algorithm across all 10 questions to determine archetype
Optimised Core Web Vitals — fixed LCP, FCP and INP issues identified in Netlify analytics
Built canvas-based Soul Card PNG export (1080×1080, Instagram/WhatsApp ready)
Deployed on Netlify with bot blocking, HTTPS enforcement, asset caching and security headers
Created all required legal pages (Privacy Policy, Terms, Refund Policy, Contact) for Stripe/Razorpay registration
Set up Razorpay payment integration for Indian users
Result: A production-ready, monetisable web app with real AI personalisation, payment infrastructure, and legal compliance — built and deployed end to end.

Which AKARI Design Looks Better? 🍣
I’ve been working on AKARI (あかり) — a Japanese food restaurant website that I’m building both as a real-shop-ready concept and as a showcase of my web design & development work.
I’ve made two different versions of the design, and I want the Contra community to decide which direction looks better.
🅰️ Option A
Design 1 — More bold, structured and brand-focused.
🅱️ Option B
Design 2 — More minimal, clean and modern.
🅲️ Option C
Neither? 😅
Tell me what you would change, add, or completely redesign. I’m open to ideas!
👇 Vote A, B, or C in the comments.
Which one would you choose for a Japanese restaurant?

I’d lean toward Design A—the bolder structure gives the restaurant a clearer point of view, while the centered dish still keeps the page inviting. The restrained palette and generous whitespace make the food do the talking.
Agent products resist normal product marketing. There's no single interface to screenshot and the category vocabulary has gone generic, so a feature list communicates almost nothing.
We built Heron's explanation as a four-beat scroll that runs the agent's actual loop. The model appears and is watched. Violations surface with plain language and a real IBC clause. An edit is applied after approval. The system learns the firm's standards.
Pacing was the main design problem. Each beat needed enough scroll distance to register as a separate action, without the section becoming so long that people bail before the payoff. The sequence carries the technical detail that would otherwise sit in a spec table.
The four-beat scroll is a smart way to make the agent’s loop feel tangible—much clearer than a static feature list. The restrained visual system gives the interaction room to breathe.
Triple2s is a digital marketing agency focused on cryptocurrency, online casinos, and iGaming businesses. While working through the discovery phase, I came across this mesmerising smoke effect, and it just clicked—it’s exactly the vibe I was going for. I’m obsessed with how it plays out, especially when you hover over the CTA. It’s such a cool, interactive moment that adds so much energy.
