Working with ISRO taught me what "production-grade" really means.

In most companies, if your model fails, someone sees the wrong recommendation or gets a bad search result. Annoying, but recoverable.

At ISRO, if your system fails, the consequences can be measured in different units entirely.

The engineering practices I absorbed there shaped everything I build:

Test more than you think is necessary. Then test more. Edge cases aren't theoretical — they're the cases that matter most.

Document every assumption. Not just for compliance — because in 6 months, you won't remember why you chose that threshold, and neither will anyone else.

Build redundancy. Every critical system has a fallback. Every fallback has a manual override. Every override has documentation.

Measure everything. If you can't observe it, you can't trust it.

These practices feel heavy when you're building a startup prototype. But they've saved me on every large-scale project since. The discipline transfers.

You don't need to work at a space agency to engineer like one. Take the rigor. Leave the bureaucracy. Apply the testing discipline, documentation habits, and monitoring practices to everything you build.

Your systems will be better for it.
