What SaaS architecture patterns do you use?
We use schema-based or row-level tenant isolation depending on security and performance requirements. We implement shared infrastructure with logical separation for cost efficiency, and can support single-tenant deployments for enterprise clients requiring data sovereignty.
Can you implement usage-based billing?
Yes. We integrate with Stripe Billing and Chargebee for metered, seat-based, and hybrid pricing models. We build event tracking pipelines to count usage in real time and surface it in customer-facing dashboards.
Do you build developer APIs and SDKs?
Yes. We design REST and GraphQL APIs following OpenAPI specifications, generate client SDKs in Python, JavaScript, and Ruby, and build developer documentation portals using tools like Mintlify or Readme.io.
How do you handle SaaS scalability?
We design for horizontal scaling from day one — stateless application layers, connection pooling, Redis caching, async job queues (Bull, Celery), and auto-scaling infrastructure on AWS or GCP. We run load tests before major launches.
