What we check early on Retail: Performance Tuning Guide, what usually goes wrong in production, and how teams avoid a rewrite six months later.
Who this is for
Use boring technology where the risk is operational. Save novelty for the one wedge that makes the product worth buying.
Decisions that still look smart in 18 months
Teams that write trade-offs down before coding burn fewer sprints when a stakeholder changes their mind mid-build. We keep ADRs short on purpose.
Build checklist we actually use
Ignore the buzzwords. For Retail: Performance Tuning Guide, the hard constraint is usually data ownership or ops capacity — not how many features fit on a roadmap slide.
Failure modes we keep seeing
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.
