Just kicked off a massive new project on Contra: Building an escrow-protected digital marketplace with crypto payment integration. 💼
This isn't just about clean UI/UX; it’s about airtight logic, security, and seamless Web3 execution. We are bringing this to life using a powerhouse stack: Next.js, Cloudflare, Supabase, farmer motion, Claude.
When a client trusts you with something as sensitive as escrow and crypto assets, it proves that your engineering and agency standards are exactly where they need to be.
Huge thanks to the client for the trust, and to @workwithcontra for connecting high-end independent talent with visionary projects. Time to architect. 🛠️

Excited to share some of the backend work I've been doing lately with Supabase! 🚀
Here's a look at what went into building a production-ready backend from scratch:
🗄️ Database Schema Design
Designed a relational schema with multiple interconnected tables: profiles, notes, reminders, conflicts, and a dedicated user_keys table for encryption key management. Every table has proper foreign key relationships, timestamps, and nullable/non-nullable constraints enforced at the DB level.
🔒 Row Level Security (RLS)
Every single table has RLS enabled with two policies: users can only access their own rows, and anonymous access is blocked entirely. No exceptions. Security is enforced at the database layer, not just the application layer.
🔑 Auth & Email Flows
Set up Supabase Auth with email + OAuth support, including full PKCE flow for secure token exchange. Configured deep link redirects for email confirmation and password reset flows, all tested end to end.
⚡ Edge Functions
Built and deployed multiple Supabase Edge Functions handling AI processing pipelines, including JWT validation at the top of every function before any processing begins. The OpenAI API key lives exclusively in Supabase secrets, never in the app or any config file.
🔄 Merge Pipeline
Built a follow-up note merge pipeline as an Edge Function. New facts are appended to existing profiles, duplicates are detected and skipped, conflicts are logged, and resolved reminders are handled gracefully.
📦 Migrations
All schema changes go through versioned migration files under source control. No manual dashboard changes. CI/CD triggers migrations automatically on merge to main.
🔐 Encryption Architecture
Client-side AES-GCM encryption via CryptoKit. Plaintext never sits in the database. Encryption keys are stored in a dedicated RLS-scoped table, fetched after login, and held in memory only for the session duration.
Still a lot more to share about this project. Excited to talk about it publicly when it launches! 👀
Interesting work! Nice 🔥 Have there been any bottlenecks so far in testing?
Creating clean, modern, and interactive web experiences with a strong focus on UI/UX, smooth interactions, and visual simplicity.
I love designing minimal yet engaging layouts that help brands, startups, and creative teams stand out online.
Working with a Webflow-oriented approach — building scalable, responsive, and aesthetically balanced websites for landing pages, portfolios, and corporate platforms.
Always open to exciting Web Design & Webflow projects ✨
Excellent 💯
📝 Project Description
Luxury Beauty Campaign Suite — From One Product Photo
This project transforms a single skincare product photo (Giv White) into a complete luxury ad campaign using Melius AI. Upload one image, and the Melius agent automatically generates a full set of production-ready creative assets.
⚙️ Process Steps
Upload product photo — One pouch photo of Giv White as the main input
Brief the Agent — Directed the agent with a "Luminous Skincare" aesthetic using an ivory and soft papaya palette with wet stone textures and caustic light refractions
Agent builds the pipeline — Melius automatically constructed node by node:
Hero Still (1:1) for Instagram feed
Vertical Social Story for Reels/TikTok
8-second Cinematic Product Film with slow macro motion
Billboard Ad (21:9)
Branded Voiceover
Review & Refinement — Adjusted prompts at each node until the output matched the creative vision
Final output — Complete campaign suite ready to use
Feedback on Melius Experience
Melius completely changed the way I work. What normally requires a full creative team and weeks of production, I finished in a single session. The agent working node by node is incredibly powerful — I could monitor and refine every stage without losing creative control. The visual canvas is intuitive, collaborative, and honestly feels like having a creative director on demand.
