In a recent sprint, one of my junior developers asked me how *LaunchDarkly * actually fits into our React-Native-Web codebase. Not just the syntax — but the system around it.
It turned into one of my best mentoring sessions this year.
We discussed the fundamentals:
- LaunchDarkly’s purpose in multi-platform environments
- Why feature flags matter more than config toggles
- How variations allow safe experimentation
- How rules can target specific user segments
- Why controlled rollouts reduce production anxiety
- And how our RN-Web setup consumes flags in a unified pattern
What surprised me wasn’t the complexity — it was how powerful these concepts become once a developer truly understands them.
Teaching this reminded me of a simple truth:
Architecture isn’t about writing code. It’s about creating decisions that future developers can trust.
And sometimes, the biggest impact you make isn’t shipping a feature…
It’s helping someone else ship one, safely.
