I am building a full-stack payment platform that sits as an application + orchestration layer on top of the Nigeria Inter-Bank Settlement System’s NQR and NIP rails. The core mandate is mass merchant enablement, while still giving consumers a frictionless QR experience. Scope The work covers everything from architecture through production rollout. You will create a scalable cloud back-end, merchant-focused web and mobile touch-points, consumer-facing apps for easy QR payment scanning, and an open API that third-party fintechs can plug into for value-added services such as data-driven lending and monetisation. Key requirements • Merchants are the primary users, so onboarding flows, settlement logic, and a dashboard that tracks volumes, fees and incentives must be rock-solid. • Consumers need three essentials: instant QR scanning, clean transaction history, and an in-app customer-support channel. • Security is non-negotiable: two-factor authentication on all sensitive actions, end-to-end data encryption (in transit and at rest), and real-time fraud detection with alerting. • The solution must be container-friendly, horizontally scalable, and instrumented for uptime, performance and audit trails. • Code should be clean, well-documented, and delivered with automated tests and a CI/CD pipeline. Deliverables 1. High-level and low-level architecture diagrams 2. Infrastructure-as-code scripts and deployment playbooks 3. Back-end microservices, merchant portal, consumer app(s) and fintech API gateway 4. Security implementation (2FA, encryption, fraud rules), plus penetration test report 5. API documentation and developer sandbox 6. Final production deployment on the chosen cloud provider, with monitoring and rollback strategy 7. Knowledge-transfer sessions and hand-over package Acceptance criteria will be tied to passing integration tests on the live NIBSS test environment and a successful pilot with a sample merchant cohort. If you have demonstrable experience with QR payments, Nigerian interbank systems, PCI-DSS compliance, and high-volume fintech platforms, I would like to review your approach, timeline, and any relevant live demos or references.

Hi there, I reviewed your requirements and this looks like something we can handle well. A payment platform sitting as an orchestration layer on top of existing infrastructure is exactly the kind of full-stack work we do regularly — especially with Rails, cloud deployment, and security baked in from the start. I have a couple of questions about your architecture approach and timeline that would help me scope this properly. Happy to jump on a quick call? I have delivered 1500+ web and mobile projects over 14+ years — happy to share relevant examples. Thanks, Hasan

I'm Iosif Peterfi, 15+ years helping teams ship scalable web platforms from Europe. This is my speciality: turning complex payment orchestration into reliable, scalable platforms that feel seamless for merchants and end-users, with a strong emphasis on security, compliance, and business agility. You're building a cloud-native back-end and touch-points for merchants and consumers, plus an open API for fintechs to plug into for value-added services, while delivering a frictionless QR payment experience and robust governance. The scope covers architecture through production rollout: scalable cloud back-end, merchant portal, consumer apps for QR payments, and a fintech API gateway, with rock-solid onboarding, settlement logic, and a merchant dashboard; instant QR scanning, clean transaction history, and an in-app support channel for consumers; security with two-factor authentication, encryption, and real-time fraud rules; container-friendly, highly available, observable infrastructure with automated tests and CI/CD; and complete documentation plus a rollback plan. I'll deliver a cohesive package: high-level and low-level architecture diagrams, infrastructure-as-code scripts and deployment playbooks, back-end services, merchant portal, consumer apps, API gateway, security controls, penetration test report, API documentation and a developer sandbox, and the final production deployment with monitoring and a clear knowledge-transfer.

Hi there, I'm excited about the NQR Payment Platform project you're working on. It sounds like you need a comprehensive solution that not only facilitates merchant onboarding but also ensures a seamless experience for consumers using QR payments. Based on your requirements, I would focus on building a robust architecture that supports scalable back-end services while prioritizing security and user experience. With 4+ years of experience in full-stack development, including payment processing and API development, I can ensure that your platform is secure and user-friendly. I understand the importance of solid onboarding flows and real-time transaction tracking for merchants, along with essential features for consumers like instant QR scanning and customer support. One question I have is: what specific regulatory compliance considerations should we keep in mind while building this platform for the Nigerian market? Best regards, Arslan Shahid

I can help with this, I will build the full platform — cloud backend microservices on NIBSS NQR and NIP rails, merchant onboarding with settlement logic and a volumes/fees dashboard, consumer apps with QR scanning and transaction history, and a fintech API gateway with developer sandbox. Security will include 2FA, end-to-end encryption, and real-time fraud detection. I will design the orchestration layer as a stateless gateway between your services and NIBSS, so every transaction is idempotent with automatic retry and reconciliation. This prevents the double-settlement and ghost-transaction issues that are common when integrating directly with NIP without an intermediary state machine. Questions: 1) Do you already have NIBSS sandbox credentials and test merchant accounts provisioned? 2) What is your preferred cloud provider — AWS, GCP, or Azure? Send me a message and we can go over the details. Best regards, Faizan

I can design and support the deployment of your NQR payment platform as a robust application and orchestration layer. I’ve worked on full-stack payment and fintech systems that sit on top of existing rails, focusing on reliability, security, and a clear user experience for both merchants and internal teams. My experience includes designing transaction flows, reconciliation views, and admin tools, along with integrating with external payment and banking APIs. I’m comfortable working across product, design, and engineering stakeholders to ensure the orchestration layer behaves predictably under real-world conditions. I’d start by clarifying your end-to-end payment journeys, mapping orchestration rules, and defining core UI states. From there, I’d iterate on high-fidelity designs, handoff-ready specs, and collaborate closely through deployment to verify the experience in a staging and production context. I would love to chat more about your project! Regards

Building a robust payment platform that seamlessly integrates with Nigeria’s NIBSS NQR and NIP rails demands a deep understanding of both the technical and user experience nuances unique to this ecosystem. The challenge lies in delivering a scalable, secure, and user-friendly solution that empowers merchants while providing consumers with a frictionless QR payment experience. This project’s scope—from architecture through production rollout—requires meticulous planning to ensure high availability, security, and smooth operations in a high-volume fintech environment. The technical approach centers on designing a cloud-native, containerized microservices architecture that supports horizontal scaling and resilience. Leveraging technologies such as Ruby on Rails for backend services, AngularJS for merchant and consumer interfaces, and robust API gateways will facilitate seamless integration with third-party fintechs. Security measures including two-factor authentication, end-to-end encryption, and real-time fraud detection will be embedded from the ground up, supported by comprehensive automated testing and CI/CD pipelines to ensure code quality and rapid deployment. Infrastructure-as-code and deployment playbooks will guarantee repeatable, auditable rollouts with full monitoring and rollback capabilities. Commitment to delivering a thoroughly documented, secure, and performant platform is paramount, with clear milestones tied to integration testing on the NIBSS environment and a pilot phase to validate merchant onboarding and transaction flows. Knowledge transfer and detailed handover packages will ensure your team is fully equipped to manage the platform post-deployment. I welcome the opportunity to discuss timelines and demonstrate how this approach will meet your objectives efficiently and reliably.
