Project Overview We are launching a high-scale 2026 Season Pass ($144/$72 Annual) for a gold-backed sub-sea mining venture. We need a Systems Architect to build the "back-end engine" that handles global payments, referral tracking, and a physical gold reserve ledger for up to 400,000 members. This is a systems-heavy build, not a UI-heavy build. The Tech Stack • Payments: Paddle (Merchant of Record). • Orchestration: Make.com. • Database/Ledger: Airtable (Enterprise-grade structure). • Identity/Security: FingerprintJS & Sumsub (KYC). • User Dashboard: Memberstack (Syncing data from Airtable). Scope of Work (The "Engine" Logic) 1. Payment-to-Ledger Loop: Trigger a [login to view URL] scenario upon successful Paddle payment. Create a member record in Airtable with a unique Referral ID and a 60-day "Vesting" countdown. 2. The "Dirty Dozen" Logic: Implement a referral counter. Upon a member’s 12th vetted (60-day) referral, automatically: • Inject +1 Bonus Token into their ledger. • Add them to a "Micro-Drawing Pool" of 25. • Trigger a winner selection once the 25th slot is filled. 3. Vault Ledger Management: Build a "Pending vs. Allocated" status system. Gold weight must move from the General Reserve to the Member's Ledger automatically after 60 days of active membership. 4. Anti-Fraud & Security: Integrate FingerprintJS data into the signup flow to flag duplicate devices or referral gaming. Integrate the Sumsub API to trigger identity verification for drawing winners. 5. Dashboard Sync: Ensure the Memberstack metadata stays in 1:1 sync with Airtable so users see their live referral progress and token balance. Requirements • Expert-level [login to view URL]: Deep understanding of Webhooks, JSON parsing, and Rate Limiting (Airtable API limits). • Airtable Architect: You must think in relational databases (Linked records, rollups, formulas). • API Security: Experience with HMAC signature verification and OAuth. • Documentation: You must provide a "Logic Map" of all scenarios for long-term maintenance. Budget & Timeline • Budget: $4,000 (Fixed Price). • Timeline: 14–35 Days to MVP. • Success Metric: A successful "stress test" of 500 simultaneous test transactions. How to Apply Please include the phrase "VAULT GUARD" at the top of your proposal so I know you’ve read the requirements. Briefly describe the most complex "multi-step" automation you have built using [login to view URL] and Airtable.

VAULT GUARD I can design and implement the full backend engine for this system using Paddle, Make, Airtable, FingerprintJS, Sumsub, and Memberstack with a strong focus on reliability, auditability, and rate-safe scaling. Relevant automation experience I recently built a multi step subscription and referral engine using Make and Airtable that handled payment webhooks, delayed vesting logic, bonus triggers, and CRM sync across several systems. The scenario included HMAC webhook validation, queue based processing to avoid API limits, and linked record ledgers with rollups and automated state transitions. It processed thousands of daily events with full audit logging and replay safety. How I would build your engine Paddle webhook to Make with HMAC verification and retry logic. Airtable structured as a relational ledger with member table, referral tree, token ledger, vesting queue, and reserve allocation tables. Dirty Dozen logic handled via queued scenario with atomic counters and pool tracking. 60 day vesting automation moves gold from reserve to allocated ledger. FingerprintJS flags stored and evaluated on signup. Sumsub triggered for drawing winners. Memberstack metadata kept in 1 to 1 sync with Airtable via controlled updates. Deliverables Full logic map of all Make scenarios Airtable schema architecture Secure webhook handling Stress test ready for 500 concurrent transactions Timeline 21 to 30 days for MVP with stress testing and documentation.

Hello, VAULT GUARD , I am immediately available. I have hands-on experience building Make.com-Airtable back-ends for large member ledgers, with secure Paddle payments, and multi-step token/vesting logic. I will implement the engine to trigger on Paddle success, create Airtable member records with a unique Referral ID and a 60-day vesting countdown, automate the 12-referral bonus, move gold from the reserve after 60 days, and ensure 1:1 sync between Airtable and Memberstack with FingerprintJS and Sumsub. I will also deliver a detailed Logic Map and a plan for stress-testing to 500 concurrent transactions. . Best regards, Mojjammil

VAULT GUARD Your architecture is exactly the type of systems-heavy automation I enjoy building. I’ve designed complex payment and automation pipelines using Paddle, Make, and Airtable, where transactions trigger multi-step workflows, ledger updates, and referral logic across multiple services. For this project, I would structure Airtable as a relational ledger (Members, Referrals, Transactions, Tokens, Reserve Pool, Drawings) and build Make scenarios that securely validate Paddle webhooks, generate unique referral IDs, and manage the 60-day vesting logic. This keeps the payment-to-ledger loop deterministic, auditable, and scalable while respecting Airtable API limits. For the “Dirty Dozen” and vault mechanics, I would implement event-driven automation where vetted referrals increment counters, trigger token issuance, and place members into the drawing pool automatically once conditions are met. Security and integrity would be handled by validating webhook signatures, capturing device intelligence via FingerprintJS, and triggering KYC checks with Sumsub before prize eligibility. I’ll also maintain a reliable sync layer so Memberstack mirrors Airtable data in near real time. Along with the build, I’ll deliver a full automation logic map, documentation, and load-test preparation to support the 500-transaction stress test and long-term scaling.

Hi, How are you? Recently, I built a 10-step automation system integrating subscription billing, escrow-style vesting, referral tiers, fraud scoring, and token rewards. It processed 800+ daily webhooks with HMAC verification, queue control, rollback handling, and structured audit logs in Airtable using linked tables, rollups, and formula-driven state transitions. For your engine, I would: • Architect a normalized Airtable base (Members, Referrals, Tokens, Reserve, Draw Pools). • Secure Paddle webhooks with signature validation + replay protection. • Implement deterministic 60-day vesting + ledger allocation flows. • Add fraud flags via FingerprintJS and conditional Sumsub KYC triggers. • Deliver a full Logic Map for long-term maintenance and stress-test readiness. A few clarifications: Should vesting pause or reset on subscription lapse? Is token-to-gold weight fixed or dynamically calculated? Do you require immutable audit logs for compliance? Any future plan beyond 400k members? I can deliver MVP within 21–28 days, optimized for the 500-transaction stress test. Best Regards
