What we check early on FinTech: Architecture Playbook, what usually goes wrong in production, and how teams avoid a rewrite six months later.
Who this is for
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.
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.
Build checklist we actually use
Ship a thin vertical slice, measure, then widen. Big-bang rewrites rarely survive the first month of real traffic.
Failure modes we keep seeing
Use boring technology where the risk is operational. Save novelty for the one wedge that makes the product worth buying.
How we measure rollout
Ship a thin vertical slice, measure, then widen. Big-bang rewrites rarely survive the first month of real traffic.
We update this when delivery patterns change on live client work.
