# OSOSS (zFloos) — A Multi-Tenant SaaS That Got 30% Faster Without New Hardware

> OSOSS's zFloos platform serves thousands of Saudi businesses on shared infrastructure. As the tenant count grew, API performance degraded. We delivered a 30% performance improvement through SQL indexing and Redis — no infrastructure changes, no downtime, and POS terminals that now never hang waiting for the cloud.

## Project context

- Client: OSOSS (zFloos)
- Industry: FinTech / SaaS
- Year: 2024

## Challenge

API response times were degrading month-over-month as the tenant count grew — a natural consequence of unindexed tenant-scoped queries becoming slower at scale. POS terminals were hanging during busy periods because transaction cloud sync was synchronous: terminal success was gated on cloud acknowledgment.

## Solution

Full query audit across all major endpoints. Composite index strategy on tenant_id + query-specific columns — delivered 30% measured improvement. Redis cache layer on dashboard aggregates with TTL matched to refresh cadence. POS sync made fully async: terminal confirms locally, cloud sync queued and processed in background with guaranteed delivery.

## Services

- Web Development
