- Terraform – Interview Questions
The questions Terraform interviews actually ask, answered the way you would say them out loud. What state is for, `count` versus `for_each`, how locking works, module versioning, what happens when someone changes something in the console, Terraform versus CloudFormation versus Ansible, and how you would recover a corrupted state file.
- Frontend Dev – Build Tooling and Deployment
What happens between your source and the files a browser downloads, and how those files get somewhere real. Bundling, the dev server, environment variables and why they are not secret, static hosting on a CDN, cache headers and content hashing, the SPA fallback that 404s every deep link if you forget it, and a CI pipeline worth having.
- Frontend Dev – Testing
How you change code you did not write without being afraid. What is worth testing in a UI and what is not, testing what the user sees rather than what the component holds, querying by role so a test breaks when the app breaks and not when a class name changes, and where end-to-end tests earn their keep.
- Terraform – Running It in Production
What changes when the state file matters. Reading a plan properly and the three words that should stop a merge, `prevent_destroy` on the things you cannot lose, drift and what to do about it, secrets in SSM instead of variables, `moved` and `import` for refactoring without destroying, least-privilege CI credentials, keeping the bill visible, and `terraform test`.
- React Native – Building and Releasing to the App Stores
The last mile, and the part web developers underestimate. `expo prebuild` and what it generates, EAS Build for machines you do not own, bundle identifiers, versioning and build numbers, environment configuration without leaking secrets, over-the-air updates and what they can and cannot change, and what App Store and Play Store review will ask you for.
