Rebuilding a fintech dashboard for real-time scale
- Problem
- A mid-market payments company's operations dashboard was built on a decade-old monolith. Report generation took minutes, data was routinely hours stale, and every new metric required a schema migration that risked downtime.
- Approach
- We extracted the reporting layer into an event-driven service, replaced batch ETL with a streaming pipeline, and rebuilt the front end as a componentized dashboard that operations staff could configure themselves — all migrated incrementally behind a feature flag so the legacy system stayed live throughout.
- Result
- Dashboard load times dropped from minutes to under two seconds, data latency fell from hours to seconds, and the operations team shipped nine new self-serve metrics in the following quarter without engineering involvement.
