OLS ERP
// the case study
Enterprise ERP serving 10,000+ users across Kuwait. Built during my Foundation Arc at OLS.
// the numbers
- faster load times (40s → 3s)
- 92%
- concurrent users
- 10K+
- corporations served
- 25+
- faster reports (30s → <2s)
- 95%
// the brief
Multi-tenant ERP serving 10,000+ concurrent users across 25+ corporations in Kuwait. Modules for finance, inventory, HR, reporting. The system that taught me what 'production scale' actually means — and where I learned to make slow things fast.
// the wins
- Cut application load time by 92% — from 40s to 3s — for 10,000+ concurrent users
- Reduced report generation by 95% (from 30s to under 2s) by rewriting 50+ SQL stored procedures
- Cleared 100+ tickets weekly through a critical staffing shortage
- Three years of production duty across 25+ corporations — the Foundation Arc
01 // the origin
Kuwait, 2021. The first place that paid me to build for real — and expected it to stay up. Multi-tenant ERP means every mistake ships to thousands of users at once. You learn fast or you stop getting deploys.
02 // the numbers
The legacy frontend took 40 seconds to load. Re-architecting the modules and the data fetching brought it to 3 — a 92% cut felt by 10,000+ concurrent users across 25+ corporations. Then the reports: 50+ stored procedures rewritten, 30 seconds down to under 2.
03 // the lesson
'Works on my machine' died here. Migrations, backwards compatibility, tenant isolation, reports that must balance to the fils. Everything since is built on this arc.
