When your API needs to work at scale and never go down
Built for production reliability
I have built API systems for production API environments. Loyalty points, stamps, vouchers, QR-based redemption, subscription management. These are not demo projects. They are designed for production use where reliability matters.
Reliability by design
I design APIs for failure tolerance from day one. Input validation, error handling, transaction safety, monitoring, and graceful degradation. A Shopify credit system I built runs at 99.9% uptime. That is not accidental. It is architectural.
Integration expertise
Connecting systems is where most API projects live. Bazaarvoice, FormStack, Exigo ERP, WordPress REST API, South African payment gateways, push notification services. I have built the bridges between these systems and the platforms that depend on them.
Node.js and TypeScript | production-grade
Node.js is my primary backend runtime. TypeScript for type safety. PostgreSQL and MongoDB for data. REST for communication. Clean architecture, documented endpoints, structured error handling. Built to be maintained, not just shipped.
API Capabilities
Node.js and API development services
Custom API Servers
Full REST API servers built from scratch in Node.js and TypeScript. Authentication, authorization, rate limiting, pagination, filtering, and comprehensive error handling. Designed for your specific business logic, not generic CRUD.
Typical work: Rewards and loyalty APIs, subscription management, billing APIs, multi-tenant systems, real-time data processing.
API & Integrations›System Integration
Connect your business systems into unified workflows. CRM to website, ERP to e-commerce, payment gateway to accounting. Bidirectional sync, webhook pipelines, and conflict resolution.
Typical work: Bazaarvoice integration, FormStack automation, Exigo ERP sync, WordPress REST API, payment gateway connections.
Microservices & Event-Driven Architecture
Break monolithic systems into focused, independent services. Push notifications, email delivery, document generation, verification services. Each doing one thing well, communicating through events.
Typical work: Push notification microservices, email verification APIs, document generation pipelines, webhook routing.
Database Architecture & Data Layer
PostgreSQL and MongoDB data-layer design for complex business domains. Multi-tenant data isolation, financial precision where required, audit trails, transactional integrity, and document models where they fit better.
Typical work: PostgreSQL design, MongoDB schema design, migration management, query optimization, multi-tenant architecture, financial precision.

Production API Scale
High-volume production traffic in production environments
I have built and maintained API systems for production environments. These systems handle loyalty programs, voucher redemption, subscription management, and QR-based verification at volumes that most developers never encounter. When your business needs an API that handles real traffic at real scale, I have already proven I can build it.

Process
How It Works
1
Map your systems
Tell me what needs to connect. I audit the existing API landscape, data flows, and integration points.
2
API design and contracts
I deliver documented API specifications, endpoint contracts, and an integration plan before writing any code.
3
Build, test, and deploy
Production-grade APIs with automated tests, error handling, logging, and monitoring. Deployed with zero downtime.
Timeline
Typical Engagements
API and backend projects vary based on complexity and integration scope:
- Focused integration: 1-3 weeks. Connecting two systems, building a webhook pipeline, or creating a specific API endpoint.
- Custom API server: 3-8 weeks. A complete REST API with authentication, business logic, database design, and deployment.
- Platform-scale system: 2-6 months. Multi-service architecture, high-volume transaction handling, and complex integration networks.
Direct Access
Production-grade engineering.
I do not build throwaway prototypes. Every API I build is designed for production. With proper error handling, documentation, monitoring hooks, and the architectural foundation to scale when your business grows.
FAQ
Frequently Asked Questions
What scale of API systems have you built?
I have built API systems for production API environments. These are production systems managing loyalty programs, voucher redemption, and subscription services in production environments.
What is your primary backend stack?
Node.js and TypeScript for API servers and microservices. PostgreSQL and MongoDB for databases. REST for API communication. I also work with webhook pipelines, real-time synchronization, and event-driven architectures.
Do you build new APIs or also integrate existing systems?
Both. I build custom API servers from scratch and I integrate existing systems. Connecting CRMs, ERPs, payment gateways, and third-party services into unified workflows.
Are you based in South Africa?
Yes. I am based in Cape Town. My company, Villiers Vision Works (Pty) Ltd, is registered in South Africa. I work with clients locally and internationally.
Can you handle high-volume production systems?
Yes. My production API systems handle high-volume production traffic. My POS system processes 5,000+ daily transactions across 7 branches. I design for reliability and scale from the start.
Need a Node.js or API developer in South Africa?
