How do I keep Terraform state manageable across teams without losing my mind?

I've been managing infrastructure for three teams across staging and production, and I've learned the hard way that Terraform state is either your best friend or your worst enemy depending on how you

We shipped goroutines everywhere and it cost us

Just wrapped up incident postmortem on a data pipeline that was eating memory like crazy. Root cause: naive goroutine spawning in our ETL workers. We were processing kafka messages and spinning up a g

Frontend testing feels like it scales backwards

I keep hitting a wall with frontend testing. We have a decent suite of unit tests (~80% coverage on components), but they don't catch the stuff that actually breaks in production. Then we layer in e2e

We got woken up at 3am because our Lambda timeouts spiked 400% after a deploy

We'd switched to Node 18 runtime and figured cold starts would be fine. They weren't. A function that usually runs in 200ms was taking 8-12 seconds on cold starts. Our traffic spikes at night (asia ti

Denormalizing early will cost you more than it saves

I've shipped two major features this year that forced this decision. First time, I normalized everything. Third normal form, proper foreign keys, the whole thing. Second time, I denormalized aggressiv

How do you handle self-referential structs in Rust without losing your mind?

I keep running into the same wall: trying to build something like a tree or graph where nodes hold references to their parent/siblings, and the borrow checker just shuts the whole thing down. I know t

How do you handle shared state across route groups in Next.js App Router?

Been rebuilding our dashboard with App Router and keep hitting the same wall. We've got three route groups that need to coordinate state (auth context, user prefs, feature flags). Context providers ar

Why did our CI/CD pipeline silently drop half our test results?

I inherited a GitLab CI pipeline that ran fine locally but dropped test reports in production. The issue: we were running tests in parallel across 10 runners, but the artifacts:reports:junit section o

Prompt engineering beats fine-tuning for most production cases

Fine-tuning looked appealing on paper. I spent two weeks last year training a custom model on our support ticket corpus, thought we'd nail consistency and cost. We didn't. The real problems: retrainin

Do you store Terraform state in S3 with DynamoDB locking or use Terraform Cloud?

I've run both setups across multiple projects, and they solve different problems depending on your team size and infrastructure maturity. S3 + DynamoDB is straightforward if you're comfortable managin
