We are building a custom internal platform for our travel advisor network. This is not a website or a Webflow project. This is a production-grade full-stack application built in Next.js and TypeScript with MongoDB Atlas as the primary database and Airtable as the CRM and operations layer. The platform includes a role-based advisor dashboard, a super admin dashboard, a custom booking submission form, commission tracking and tier logic, five admin report types with CSV exports, secure invoice file storage, transactional email workflows, and integrations with Airtable, Webflow CMS, Mailgun, Cloudinary, and a private object storage service such as AWS S3 or Cloudflare R2. We have a detailed internal technical proposal covering architecture, phased delivery plan, data models, role and permission structure, milestone definitions, and cost modeling. You will receive the full document before any engagement begins. This is a fixed price milestone based engagement across five phases over approximately eight weeks. All source code, accounts, and assets are owned by Xullu throughout the project. Do not apply with a generic proposal. Your application must include a live production Next.js application you have built, your approach to Airtable API caching for high volume reporting, your approach to secure financial document storage with server side access control, and your fixed price broken down by milestone. Budget range is $10,000 to $14,000. We are not looking for the lowest rate. We are looking for the most qualified.

ABOUT THE PROJECT I’m building a premium concierge matchmaking service that connects people through a thoughtful, human-curated process. This isn’t a swipe-based app or a subscription platform. It’s a carefully designed member experience where real people are matched by hand and meet in person. I’m looking for a developer who wants to build something meaningful from the ground up. The product is entirely digital but deeply human, and the person building it should care about both of those things. The project has a well-defined scope, a detailed brief, and a founder who has done the strategic and operational thinking upfront so you’re not figuring out requirements as you go. This is a founder-budgeted project, not a corporate one. I’m looking for someone who uses every tool available to work efficiently and deliver a production-ready build at a price that reflects a smart, modern development workflow rather than traditional hourly rates on a blank canvas. If you’ve developed a system for using AI coding tools intelligently as part of your process, I want to hear about it. WHAT YOU’LL BUILD A custom web application handling the full member journey from first click to post-meetup follow-through. The core components: Marketing site with clean, branded design (style guide and brand assets provided) Member application flow covering account creation, email verification, terms acceptance, payment collection, identity verification, intake survey, and confirmation screens Stripe Payments integration for two separate fee collections at different points in the member journey Stripe Identity integration for government ID scan and liveness verification, which is a safety feature core to the product Twilio integration for phone OTP verification and outbound SMS communications throughout the member journey Member database storing intake responses, verification status, match pairings, and journey history Admin dashboard for the founder to manage members, view pipeline status, track match confirmations, and receive operational notifications when key events occur Automated logic for time-sensitive business rules including a 48-hour confirmation window with conditional branching and a 7-day rematch guarantee with automatic Stripe refund trigger Resume flow for members who drop off mid-application Referral program integration Post-meetup feedback survey with conditional contact exchange logic and safety flag escalation to the founder THE TECH I’m looking for a Node.js developer who is comfortable working across the full stack. Beyond that I don’t prescribe the approach. If you have a preferred framework, database, or architecture that fits this scope and lets you work efficiently, make the case for it in your proposal. I’m open to AI-assisted development workflows. If you’ve trained or refined how you use AI coding tools and know how to validate, own, and implement the output at a production level, that’s a genuine asset on a project like this. What I care about is that you bring real expertise to every decision the AI can’t make for you, including security, data handling, edge cases, and the integrations that require deep API knowledge. Smart use of available tools is part of how we get to a founder-friendly budget without cutting corners on quality. WHAT I’M LOOKING FOR Solid full stack experience with Node.js. This is a production application handling payments and biometric identity data, not a first project. Demonstrated experience with Stripe API integrations. Stripe Identity experience specifically is a strong plus and worth calling out in your proposal. Experience with Twilio or comparable SMS and verification APIs. Comfort building member-facing web applications with authentication, gated content, and user-specific flows. A security-conscious mindset. You understand that handling government ID scans, liveness data, and payment information carries real responsibility and you build accordingly. Clear communication skills. You’ll be working directly with a non-technical founder and explaining what you’ve built in plain language is part of the job. Ability to document your work thoroughly. Loom walkthroughs and written technical documentation are required deliverables, not optional extras. A modern, efficient approach to development. Whether that means AI tooling, well-chosen frameworks, reusable components, or a workflow you’ve refined over time, I want someone who works smart and can speak honestly to how they arrive at their pricing. ENGAGEMENT STRUCTURE Initial build: fixed price project. Please provide your estimate based on the scope above. I have a realistic founder budget and I’m not looking for the lowest bid. I’m looking for someone who builds things that work reliably, takes pride in the craft, and uses a smart efficient workflow to make the numbers work for both of us. Ongoing retainer: after launch I’d like to keep you on a light monthly retainer for maintenance, monitoring, and occasional additions as the business grows. Scope and rate to be discussed before project close. CODE OWNERSHIP All code, design, and intellectual property produced during this engagement transfers fully and exclusively to me upon payment. You retain no ownership, licensing rights, or claim to any part of the codebase, design assets, or documentation produced for this project. This is non-negotiable and will be reflected in our written contract before work begins.
