How we choose a stack
Fit for purpose
We pick technology for your requirements, team skills and budget, never because it's trendy.
Easy to hire for
Mainstream, well-documented stacks so you can grow an in-house team around the code later.
Secure & supported
Mature ecosystems with active security patching and long-term support.
Built for performance
Architectures and frameworks that stay fast as your users and data grow.
