How we choose
Four principles behind every technology decision
We don't chase trends. A technology joins our stack only when it makes your software easier to scale, secure and maintain.
Mainstream and long-lived
Popular, actively maintained open-source tools with large ecosystems — easy to hire for and safe to build on for years.
TypeScript end-to-end
One strictly typed language across web, API and React Native, with types shared from a single source of truth.
Secure by default
Validation, authorization, hashing, sessions and rate limiting are standard parts of the stack, not optional extras.
Chosen for continuity
Because 100+ developers know the same tools, any engineer in our pool can maintain or extend your project.
