Industry: Enterprise SaaS

Location: Ethiopia

What Made This a Good Bet

Water utility companies were managing billing and meter reading manually or with fragmented spreadsheet-based systems.

Errors in manual billing led to revenue loss and frequent customer disputes.

No centralised system existed for managing customer accounts, payment history, and meter data at scale.

Water utility billing errors have direct consequences for both revenue and customer service access.

Manual processes could not scale as organisations grew their customer base.

Deployment across multiple organisations required a multi-tenant architecture with strict data isolation.

What I Built

Architected and owned the complete frontend including billing, meter management, and reporting modules.

Built high-load dashboards capable of displaying real-time data for 100,000+ users without performance loss.

Implemented a CI/CD pipeline with Docker and Nginx that reduced deployment time by 70%.

Designed the multi-tenant UI layer with per-organisation theming and data isolation.

Delivered consistent zero data integrity issues across all production deployments.
