Overview I’m building an AI-powered wedding planning platform and need a senior-level full-stack engineer to take over integration and evolution of the product. This is not a simple embed task. The core AI product already exists in [login to view URL] and is deployed. A Webflow marketing site has also been built. The next stage is to properly integrate the two, refine the architecture, and continue evolving the product into a scalable SaaS platform. I’m looking for someone who can think beyond implementation and help shape a production-ready system. ⸻ Current Architecture Application Layer • [login to view URL] 15 (App Router) • React 19 • Hosted on Vercel • OpenAI integration (AI wedding planner) • Clerk authentication • Stripe billing • Supabase / Postgres database Features Already Built • AI wedding planner • Vendor discovery • Messaging & inquiry system • Quote collection & negotiation • Booking confirmation flow • Checklist management • User dashboard Marketing Layer • Webflow site • Custom rose-glass design aesthetic • Landing & pricing pages built • Needs structured integration with the app ⸻ What I Need Phase 1 – Architectural Integration Not just iframe insertion. We need a proper integration strategy between Webflow and the [login to view URL] app that: • Preserves performance • Maintains authentication integrity • Avoids security policy conflicts (CSP / frame-ancestors) • Ensures seamless UX • Supports future feature growth Options may include: • Subdomain architecture • Micro-frontend approach • Controlled embedding • Reverse proxying • Or full migration strategy if appropriate I’m open to recommendations from someone experienced. ⸻ Phase 2 – Product Refinement & UI Evolution The Webflow site is not final. Sections will need: • Rebuilding and restructuring • AI feature positioning • Conversion-focused UX improvements • Interactive elements • Embedded product experiences • Ongoing iteration This is not a static website job — the marketing site must evolve alongside the product. ⸻ Phase 3 – AI Feature Expansion The AI planner is live but will require: • Prompt refinement • Output structuring improvements • Performance optimisation • Model evaluation • Potential feature expansion (budget modelling, vendor scoring, itinerary builder, etc.) ⸻ Technical Requirements You must have real-world experience with: • [login to view URL] App Router (production deployment) • Vercel environment management • OpenAI API integrations • Stripe subscription logic • Postgres / Supabase • Authentication systems (Clerk or similar) • Cross-origin security & CSP handling • SaaS architecture design Bonus if you have: • Experience building AI SaaS tools • Product thinking • Experience integrating Webflow with custom apps • Strong UI/UX sensibility ⸻ Not Suitable If • You primarily build static Webflow sites • You’ve never deployed an AI-powered production app • You don’t understand CSP / iframe policies • You can’t explain tradeoffs between architectural approaches ⸻ Deliverables • Clean integration between Webflow and application layer • Production-ready deployment structure • Security reviewed & hardened • Refined AI experience • Documentation of architecture • Scalable foundation for growth ⸻ Engagement This is not a one-off task. I’m looking for a long-term technical partner to help evolve this platform into a serious AI SaaS product. ⸻ Budget Open to fixed-price or milestone-based proposals. Please propose based on scope and architecture approach. ⸻ To Apply Please include: 1. 2–3 AI-powered SaaS products you’ve built or contributed to 2. Your proposed integration architecture approach 3. Your preferred stack refinements (if any) 4. Estimated timeline for Phase 1 5. Whether you’d structure this as project-based or ongoing retainer

Hi there To evolve this into a serious AI SaaS platform, the most critical part is defining a clean boundary between the marketing layer and the application layer without breaking auth, billing, or performance. This isn’t an embed problem — it’s an architecture decision. I’ll approach this by evaluating subdomain isolation with shared session strategy, edge middleware for auth continuity, and controlled routing between Webflow and Next.js. That ensures Clerk sessions, Stripe subscriptions, and Supabase data remain secure while UX feels seamless. From there, the focus shifts to tightening AI output structure, prompt orchestration, and latency optimisation so the planner feels production-grade rather than experimental. My process is simple. Define integration architecture with clear tradeoffs. Implement hardened deployment across Vercel with environment isolation. Refine AI flows, performance, and UI alignment iteratively. I will provide a precise timeline and detailed budget once architecture scope is fully confirmed. If this direction aligns, let’s discuss in detail via private chat.

As an experienced and versatile full-stack engineer, I have the complete skill set necessary to take on your project and drive it to success. I've built several AI-powered SaaS products, ranging from mobile apps to web platforms, and my past work has revolved around creating intricate processes that require seamless integration. This aligns perfectly with what you're seeking for Phase 1 of your project. In terms of my architectural approach, I propose a subdomain-based system, which will not only preserve performance and improve security but also offer potential for future feature enhancements. For the Webflow site that needs refining, my strong sense of UI/UX design will allow me to rebuild sections strategically while keeping a conversion-focused approach in mind - this prevents a static website job and ensures that the marketing site can evolve alongside the product.
