A practical cut of FinTech: Observability Guide for engineering and product leads — decisions first, framework essays last.
Who this is for
Ship a thin vertical slice, measure, then widen. Big-bang rewrites rarely survive the first month of real traffic.
Decisions that still look smart in 18 months
Instrument the happy path and the ugly path. Silent failures are what turn a launch into a weekend incident.

Ship a thin vertical slice, measure, then widen. Big-bang rewrites rarely survive the first month of real traffic.
How we measure rollout
Instrument the happy path and the ugly path. Silent failures are what turn a launch into a weekend incident.
We update this when delivery patterns change on live client work.
