Deep Capabilities
What Our Backend Engineers Are Actually Judged On
We screen for production judgement, not framework trivia, alongside our API and data teams.
Data Modelling Judgement
Schema decisions made with the read patterns in mind, because that is what you live with later.
Designed for Failure
Retries, idempotency and timeouts treated as requirements rather than incident follow-ups.
Observability Built In
Structured logs, traces and metrics added while building, not during the outage.
Queue and Async Fluency
Knowing what belongs in a request cycle and what should never have been synchronous.
Security Discipline
Authn, authz, secrets and input handling done correctly the first time.
Test Coverage That Pays
Tests at the boundaries that catch regressions without freezing the design.

FAQ
Questions We Hear Every Week
Node.js, Python, Java, Go and PHP with Laravel. Each engineer works in their language daily and has operated it in production, so they know how it behaves under load rather than only how to write it.
