The systems your users never see but depend on constantly

The backend handles product logic, permissions, workflows, integrations and data. We select backend technologies based on complexity, scale, existing infrastructure and the development model required.

  • We choose technology based on the product, team and business problem
  • The stack serves the product — not the other way around
  • Node.js
  • Python

Core technologies

What we use in this category

Firebase

Best for: Async workloads, webhooks

Cloud Functions

Event processing without managing persistent servers.

Best for: Integrations, mobile, web

REST APIs

Clear HTTP contracts between clients and services.

GraphQL

Best for: Complex client data needs

GraphQL

Flexible querying when clients need shaped data graphs.

What we build

Backend that matches the workload

We do not default to the same backend for every product. Node.js, Python, Firebase and serverless each win for different constraints — and we will say when a simpler SaaS product is better than building at all.

  • API design
  • Authentication
  • Permissions
  • Workflow engines
  • Payment processing
  • Background jobs
  • AI orchestration
  • Third-party integrations
  • Event processing
  • Data synchronization

FAQ

Questions teams ask

Straight answers on stack choices, fit, and how we engage.

Node.js is excellent for APIs and TypeScript-aligned teams. Python is often stronger for AI, data processing and automation. Many products use both.

No. Firebase is strong for rapid SaaS and real-time products. Complex relational workloads or certain enterprise constraints may call for PostgreSQL or another architecture.

Yes. We assess the codebase, stabilize delivery, and either modernize in place or plan a staged migration.
