T-Square Verify Project: Automated Identity Verification & Wallet Portal

We are launching T-Square Verify, a commercial web portal to allow local users to perform automated identity verifications for NIN and BVN checks. The system will use a pre-funded wallet, with real-money deposits and seamless deductions per search, including a profit markup. We require the backend to be highly secure and precise, ideally using Laravel/PHP or Node.js, to manage transactions without errors or race conditions. The portal needs integration with local payment gateways like Paystack, Monnify, or Flutterwave, utilizing secure webhooks for automated wallet funding. Integration with third-party KYC APIs is necessary to validate identities against official databases. You will be responsible for developing a secure database (MySQL/PostgreSQL) with strict ledger integrity and detailed audit logs for all transactions. Automated error handling must ensure client’s wallets are not debited in case of failed government database connections. We seek a full-stack web developer or backend engineer experienced in fintech systems, payment APIs, and cryptographic data security.

T-Square Verify
​Project Title: Development of an Automated Identity Verification & Wallet Portal
Platform Architecture: Web-based (Responsive Mobile-First)
Hosting Environment: Shared Linux Server (cPanel / Truehost Nigeria)
​Project Overview
​We are launching T-Square Verify, a commercial portal allowing local users to perform automated identity verifications (NIN and BVN checks). The system must operate on a pre-funded wallet system where users make real-money deposits, and deductions are made seamlessly per search with a built-in business profit markup.
​Core Technical Requirements for the Developer:
​Secure Backend Architecture: Must be built using a robust, secure framework (e.g., Laravel/PHP or Node.js) capable of handling precise database transactions without race conditions.
​Payment Gateway Integration: Integration of local payment processing gateways (Paystack, Monnify, or Flutterwave) utilizing secure Webhooks to ensure instant, automated wallet funding upon successful transaction verification.
​Third-Party KYC API Consumption: Integration of REST APIs from local KYC identity infrastructure providers (e.g., Dojah, Monnify API, or Smile ID) for live database querying against official records.
​Database Management & Ledger Audit Logs: Design of a highly secure database (MySQL/PostgreSQL) that maintains strict ledger balance integrity. Every single transaction (deposits, failed attempts, and successful queries) must leave an immutable timestamped log to prevent financial manipulation.
​Automated Error Handling: Implementation of automated fail-safes so that if a third-party government database is down, the user’s wallet is completely protected against double-deduction.
​What We Are Looking For:
​We need a Full-Stack Web Developer or Backend Engineer who specializes in fintech applications, third-party API configurations, and cryptographic data security.
