Thin frontend
The interface presents and interacts. Business rules, authorization, and data integrity stay in the backend.
Engineering
Reliability is designed into the product.
Architecture, security, experience, and operations are not separate concerns. Together, they let a product work correctly today and change safely tomorrow.
Architecture
Start simple. Keep the boundaries strong.
Architecture follows the product's real needs. We choose clear modules and ownership over unnecessary distribution.
Modular backend
We keep strong boundaries inside one application and separate only when a real need appears.
API-first
We make data and error contracts explicit, validate at the boundary, and manage change deliberately.
Correctness
Find mistakes before users do.
Types, schemas, and automated checks expose problems before they reach production.
Strict type safety
Strict TypeScript and shared contracts reduce ambiguity before the code runs.
Validation at boundaries
We validate configuration and external data before use.
Risk-based testing
Tests protect business rules, integration boundaries, and critical behavior.
Production
Working locally is not enough.
Delivery should be repeatable, operation visible, and behavior predictable.
Repeatable builds
Locked dependencies, clean environments, and multi-stage images produce consistent results.
Small runtime surface
Production images carry only what they need and run as non-root users.
Visible health
Health endpoints, structured logs, request IDs, and graceful shutdown make diagnosis easier.
Longevity
Software that is easy to change lasts longer.
Clean engineering is not a style. It is how a product keeps moving safely.
Few dependencies
Every new package must justify its maintenance, security, and product cost.
One source of truth
Routes, locales, environment, and API contracts stay centralized.
Good developer experience
Clear commands, fast feedback, and production-aligned local work make the right change easier.
