migration

Engineering
The strangler fig pattern, in practice
Incremental migration sounds obvious until you have to route live traffic. Here is what it actually takes.

Data & AI
You cannot ship an LLM feature without an eval suite
Manual spot-checking does not scale past the demo. Offline evals are the difference between a prototype and a product.

Cloud & Reliability
SLOs that mean something to the business
Ninety-nine point nine of what, measured where? Most SLOs measure the wrong thing.

Design & Product
Design systems that survive the handover
Most design systems decay within a year. The ones that do not share three properties.

Engineering
Postgres is probably enough
Before adding a fourth datastore, check what Postgres already does.

Cloud & Reliability
Cloud cost is an architecture problem
Rightsizing gets you 20%. Architecture gets you the rest.

Design & Product
Accessibility is cheaper when you start early
Retrofitting WCAG compliance costs several times what building it in does.

Cloud & Reliability
Observability beyond dashboards
If you only know what you thought to graph, you do not have observability.

Data & AI
Retrieval quality beats model choice
Teams spend weeks comparing models and days on their retrieval pipeline. The ratio should be reversed.

Security
A secure SDLC that does not slow delivery
Security gates that add a week get routed around. Here is what works.

Data & AI
Why your data team spends its week firefighting
Untested transformations and undefined ownership produce a permanent incident queue.

Engineering
Choosing boring technology on purpose
Innovation tokens are finite. Spend them where they differentiate you.
