We are seeking a top-tier Technical Architect to lead the development of a sophisticated, high-concurrency auction marketplace for high-value physical assets. The platform connects private sellers with a curated network of professional B2B buyers. The goal is to replace traditional, static listing methods with a data-driven, automated, and lightning-fast auction experience.
Workflow Expectation: We value efficiency. We are looking for an AI-native developer who masterfully uses Cursor, Claude 3.5, and LLMs to deliver production-grade code 3x faster than traditional methods. You should be an expert in leveraging SaaS boilerplates to avoid reinventing the wheel on standard features.
Core System Modules & Technical Depth
- Intelligent Asset Intake & AI Quality Assurance
- Dynamic Onboarding: A multi-step seller flow where users enter unique identifiers (IDs/Serial numbers). The system must asynchronously fetch data from external technical APIs to pre-populate specifications.
- AI Vision Integration: Implementation of a Vision-based QA system. Upon uploading 15–25 images, the system must:
- Validate required angles and perspectives.
- Analyse and flag visual damages or anomalies vs. the seller's verbal description.
- Perform OCR on technical documents to verify ownership and asset history.
- Pre-Auction Certification: Automatic triggering of 3rd party background checks (History, Liens, Legal status). Only assets with a "Verified Certificate" can enter the live pool.
- High-Concurrency Real-Time Auction Engine
- Batch Auction Logic: Auctions are not random; they are triggered in daily batches (e.g., every day at 14:00).
- Real-Time Synchronization: Use of WebSockets or Supabase Realtime to sync bids across hundreds of concurrent users with sub-millisecond latency.
- Advanced Bidding Features:
- Proxy Bidding: Automated bidding up to a user's maximum limit.
- Anti-Sniping: Automatic extension of the auction timer if a bid is placed in the final 60 seconds.
- Reserve Price Logic: Handling of "Sold" vs. "Under Reserve" status with automated post-auction notifications.
- Professional Buyer (B2B) Ecosystem
- Subscription-Gated Access: Integration with Stripe Billing for monthly tier-based access (Starter, Pro, Elite).
- Verified Profiles: A vetting workflow where buyers must upload business credentials (ID, Tax details) for Admin approval.
- Personalised Bidding Dashboard: Advanced filtering, watchlists, and real-time "Outbid" alerts (Push/SMS/Email).
- Robust Operational Admin "OS"
- RBAC (Role-Based Access Control): Granular permissions for Admins, Verifiers, and Support staff.
- Listing Supervision: A command center to approve/reject listings, edit AI-detected errors, and manage the auction queue.
- Financial Oversight: Tracking of successful transactions, success fee invoicing, and subscription churn.
- Dispute & Mediation: A dedicated workflow for handling post-auction discrepancies between seller and buyer.
- Data Intelligence & Analytics Warehouse
- Proprietary Pricing Database: The system must capture every data point (initial estimate, opening bid, final bid, dealer behaviour) to build a market-leading valuation engine.
- Success Analytics: Automated reporting on sales conversion rates, popular asset types, and regional demand trends.
Monetization & Payment Architecture
- Hybrid Model: Implementation of Stripe Connect.
- Recurring: Monthly B2B subscriptions.
- Transactional: Dynamic "Success Fees" (2–7% of the final price) automatically calculated and invoiced/deducted upon auction confirmation.
Tech Stack Requirements
- Frontend: (App Router), TypeScript, Tailwind CSS.
- Backend/Database: Supabase (PostgreSQL, Edge Functions, Realtime, Storage).
- Real-time Layer: Supabase Realtime, Pusher.
- Payments: Stripe (Billing & Connect).
- Integrations: Resend (Email), Twilio (SMS), Vision APIs (GPT-4o/Claude).
- Infrastructure: Vercel.
