Frequently Asked Questions

What's the difference between Node.js and Python for commerce backends?

Node.js excels at real-time, event-driven systems with non-blocking I/O, perfect for live inventory updates and concurrent connections. Python dominates AI/ML tasks—autonomous agents, demand forecasting, and fraud detection. Most modern commerce platforms use both: Node.js for APIs, Python for intelligence layers.

How do microservices improve commerce scalability?

Microservices break monolithic apps into independent, loosely-coupled services. Each scales independently—your pricing service handles load spikes separately from your inventory service. This prevents one bottleneck from crashing the entire platform, reduces deployment risks, and enables teams to work in parallel.

How does GraphQL improve API efficiency?

GraphQL lets clients request exactly the data they need—no over-fetching. Instead of 10 REST endpoints returning redundant data, one GraphQL query returns precisely what you ask for. Reduces bandwidth, improves performance, and eliminates N+1 query problems common in REST APIs.

What's the typical backend development timeline?

API development: 4-6 weeks for core commerce endpoints (products, orders, payments). Microservices architecture: 6-10 weeks for full service decomposition. AI integration: 4-8 weeks for autonomous agents. Total backend implementation typically takes 12-20 weeks depending on complexity and integrations required.

What's the cost difference between monolithic and microservices architecture?

Initial microservices setup costs more—infrastructure, DevOps tooling, team coordination. But long-term, microservices win: independent scaling reduces wasted infrastructure, faster deployments mean quicker time-to-revenue, and selective updates reduce testing overhead. Typical ROI: 18-24 months.
