Field notes from production
Patterns, post-mortems and technical deep-dives drawn from real engagements. Practical lessons — no filler.
Why we stopped using Helm for everything
Helm got us to production fast. Then it slowed us down. How we moved to a Kustomize-first workflow and what broke along the way.
RAG at scale: lessons from production traffic
Vector databases, embedding strategies, and the chunking decisions that make or break retrieval quality in production.
The observability stack that reduced our on-call burden
OpenTelemetry, Datadog, and structured logging — how we built a signal-not-noise alerting culture from scratch.
Zero-trust in practice, not in slides
How we implement zero-trust networking for container workloads using Istio service mesh and Vault-managed secrets rotation.
FinOps that made a measurable difference
Spot instances, right-sizing and reserved capacity — the unglamorous work that cut a real cloud bill without reducing capability.
Decomposing a monolith without disrupting the business
The strangler fig pattern in practice: dual-writes, feature flags and the moment you can finally decommission the old system.
