I built an AI-powered workflow that helps real estate professionals turn property details into polished listings for websites, property portals, and social media. Using Gemini and n8n, it generates the content, highlights key selling points, and flags missing information. Before anything is saved to Airtable, the listing is sent via WhatsApp for approval.

Having the listing go to WhatsApp for approval before anything lands in Airtable keeps a human in the loop without slowing the flow down. When Gemini flags missing property info, does the approver fill the gaps in WhatsApp, or does it loop back through n8n for a regenerate?

Hygor Cinematic - scroll-driven cinematic landing page (personal concept). Instead of stacked sections, the page plays like a film: the photo stays on stage (sticky) while panels, service cards and chapters move in and out around it as you scroll, ending in a portfolio and a call to action. Dark, minimal palette with a subtle blue accent. Built with Next.js, Tailwind and Framer Motion; on mobile the panels move below the photo so they never cover the face.
