Built an Afro-Caribbean inspired AI recipe app š² that you can type a prompt, get a beautiful recipe card with ingredients, tips, and culture. Still in progress, but I love where itās going. āļø Note: This version of the app is still in beta testing. Iāve been experimenting on the free tier, and I used up my initial free credits which honestly says a lot about how much Iāve been testing and refining it š . This is an early build, but I wanted to share the progress, show whatās possible, and hear your thoughts. š¬ Let me know what you think so far what would you add, improve, or love to see next? š Try the demo: https://eb885ab8-0b65-43c1-b56f-a3ead8705fe5.web.createdevserver.com (https://eb885ab8-0b65-43c1-b56f-a3ead8705fe5.web.createdevserver.com/) #AnythingChallenge

Luxury isn't just a product; itās an atmosphere. I recently developed this visual campaign concept, "Love in Bloom," using Christian Diorās Hypnotic Poison as the muse. My goal was to bridge the gap between gothic romance and modern sophistication. By integrating deep floral textures with high-contrast lighting, Iāve created a narrative that speaks to the "hypnotic" essence of the brand. What I brought to this project: ā¢ Art Direction: Concept development from "mood" to final execution. ā¢ Visual Storytelling: Creating a cohesive aesthetic across product and lifestyle shots. ā¢ Brand Alignment: Ensuring every frame feels like a natural extension of the Dior universe. Looking to elevate your brandās visual identity? Letās build something unforgettable. :

This one was part of a concept were i explored AI-generated cinematic UI mockups. I used this prompt to generate a realistic NYC weather forecast interface that looks like it belongs in a sci-fi film, yet grounded in everyday use. Use cases.. Perfect for explainer videos, UI/UX inspiration, futuristic product demos, or content creators building immersive visual environments. Prompt used: Visualize the current live weather report for New York City. Render it as a futuristic, high-fidelity glass UI widget floating over a rainy NYC street background. Use accurate real-time data.

AI Patient Communication System for Oral Surgery Practice Problem: Oral surgery practice struggled with patient communication inefficiencies. Patients had questions about procedures, recovery protocols, pre-op instructions, and insurance coverage but couldn't get timely answers. Front desk staff spent 15+ hours weekly answering repetitive questions via phone, taking time away from scheduling and practice operations. Missed calls led to patient frustration and appointment cancellations. Results: - Practice reduced front desk call volume by 40%, freeing up 6+ hours weekly for higher-value tasks. - AI system handled 200+ patient inquiries in first month with 95% resolution rate (no human handoff needed). - Appointment no-show rate decreased 15% - System paid for itself in 2 months through reduced administrative overhead.

Varia for E-commerce: The AI-Powered Search Bar (20% Conversion Rate) The Challenge: Traditional e-commerce search is broken. Customers don't know what to search for, product pages can't answer specific questions, and "add to cart" without confidence leads to abandonment. A customer searches "best protein for weight loss" and gets 47 products with no guidance. They leave. Results (Protein Factory - Supplement E-commerce): - $50K in direct sales attributed to Varia in 3 months, AOV = $80 - 20% conversion rate (typical e-commerce: 2-3%) - 10% engagement rate (customers actively asking questions)

Varia: AI Sales Agent Platform (20% Conversion, $100K ARR) Built Varia, an AI sales agent that explains products, answers questions, qualifies leads, and tracks engagement: all in one intelligent conversation. The Challenge: Traditional sales funnels lose prospects between discovery and purchase. Static landing pages can't answer questions. Human sales calls don't scale. I wanted to create something that feels personal but works asynchronously. Results (First 6 Months): - 5,000+ prospects engaged across education, real estate, ecommerce - 20% conversion rate (2-3x typical funnel benchmarks) - 55% engagement rate (prospects actively asking questions) - $25K in sales within 3 months - Projected $100K ARR Example deployments: Protein Factory, Invivo Healthcare,
