ROBUST
BACKEND SYSTEMS
THAT POWER
PERFORMANCE
Scalable backend infrastructure built with Node.js, PostgreSQL and modern architecture. We create reliable APIs that handle millions of requests without breaking a sweat.
IS YOUR BACKEND HOLDING YOU BACK?
Your backend infrastructure is the backbone of your application. When it fails, everything fails. Here's what's costing you:
Slow API Response Times
APIs taking 3+ seconds to respond create frustrated users and abandoned transactions. Every millisecond of delay costs you conversions and revenue.
Scalability Issues
Your system crashes during traffic spikes or peak hours. Growth becomes your enemy when your infrastructure can't scale with demand.
Security Vulnerabilities
Weak authentication, exposed endpoints and unencrypted data put your business at risk. One breach can destroy years of trust and reputation.
Poor API Integration
Connecting third-party services takes weeks instead of days. Fragile integrations break constantly, requiring constant maintenance and firefighting.
Database Performance Problems
Unoptimised queries and poor database design create bottlenecks. Your app slows to a crawl as data grows, forcing expensive rewrites later.
Missing Documentation
Developers waste hours figuring out undocumented APIs. Onboarding takes weeks and every integration becomes a painful guessing game.
SCALABLE BACKEND SYSTEMS BUILT RIGHT
We build enterprise-grade backend systems using the same architecture that powers platforms like Spotify, Slack and Netflix. Your infrastructure becomes your competitive advantage.
Node.js & Express
Lightning-fast APIs built with asynchronous architecture. Handle thousands of concurrent requests with minimal server resources.
PostgreSQL & MongoDB
Rock-solid database design with proper indexing and query optimisation. Your data stays reliable and performant at any scale.
RESTful & GraphQL APIs
Modern API design following industry standards. Well-structured endpoints that are easy to consume and maintain.
Microservices Architecture
Modular services that scale independently. Update one component without risking the entire system.

CASE STUDIES
From 2s to 85ms API Response Time
Challenge: Payment processing platform struggling with slow API responses during peak hours. Transaction failures costing $30,000 NZD monthly in lost revenue.
Solution: Rebuilt backend with Node.js and PostgreSQL, implemented Redis caching, optimised database queries and added horizontal scaling with load balancing.
Results:
- Average response time reduced from 2000ms to 85ms
- System now handles 50,000 requests per minute
- Transaction success rate increased to 99.7%
- Infrastructure costs reduced by 40%
Scaled to 100,000 Users with Zero Downtime
Challenge: Project management SaaS experiencing daily crashes as user base grew. Monolithic architecture couldn't scale, threatening business survival.
Solution: Migrated to microservices architecture with GraphQL API, implemented event-driven workflows and deployed on containerised infrastructure with auto-scaling.
Results:
- Scaled from 5,000 to 100,000 active users
- Zero downtime during migration
- 99.98% uptime over 12 months
- Development velocity increased 3x

What You Get With Every Package
FREQUENTLY ASKED QUESTIONS
What's the difference between REST and GraphQL APIs?
REST is simpler and works well for straightforward data needs, while GraphQL gives clients more control to request exactly what they need. We recommend REST for most projects unless you have complex data requirements or need to minimise network requests.
How do you ensure API security?
We implement JWT token authentication, HTTPS encryption, rate limiting to prevent abuse, input validation and sanitisation, role-based access control and regular security audits. Your API endpoints stay locked down and protected.
Can you work with our existing backend?
Absolutely. We can audit your current system, optimise performance, add new features or gradually migrate to a modern architecture without disrupting your live application. We work with legacy systems all the time.
Which database should I use?
PostgreSQL is perfect for structured data requiring complex queries and transactions. MongoDB works well for flexible schemas and rapid development. MySQL is solid for traditional relational needs. We help you choose based on your specific requirements.
How do you handle API versioning?
We implement URL-based versioning (like /v1/ and /v2/) to maintain backwards compatibility while introducing new features. Old versions stay active so existing integrations keep working while you migrate at your own pace.
What if my app suddenly goes viral?
We build with horizontal scaling in mind from day one. Your backend can handle sudden traffic spikes by automatically spinning up additional servers. Combined with caching and load balancing, your system stays responsive under pressure.
Do you provide API documentation?
Yes. Every project includes comprehensive OpenAPI/Swagger documentation with interactive playground, code examples and authentication guides. Your developers get everything they need to integrate quickly.
Can you integrate with our existing tools?
We integrate with hundreds of platforms including Stripe, PayPal, Salesforce, HubSpot, Shopify, Mailchimp, AWS, Google Cloud and more. If it has an API, we can connect it to your system.
