A shared view of field-service work.

The problem

A repair belongs to a larger service history.

Maintenance work connects people, clients, branches, machines, visits, and parts. A ticket register alone does not describe the entire operation. Managers, engineers, and operators need views that match their responsibilities while referring to the same service records.

My responsibility

My part: the workflows and supporting data layer.

At Big Data Egypt, I built the React ticketing frontend and took on supporting full-stack responsibilities with Supabase. My scope included the PostgreSQL schema, authentication, API integration, role-specific dashboards, maintenance scheduling, spare-parts tracking, PDF reports, and document storage.

The platform organizes machines by client and branch, supports ticket assignment through database functions, and includes tools for importing Excel records. These capabilities bring repair coordination and the records around it into a shared application.

Implementation & tradeoffs

Match each interface to the work behind the role.

Managers, engineers, and operators have role-specific portals. The interface presents the workflows relevant to each group, while Supabase row-level security constrains access at the data layer. This is a different responsibility from simply hiding a navigation item in the browser.

Reusable frontend components support the different operational screens. Maintenance reports are generated as PDFs and stored using Supabase Storage. Connecting reporting with service records reduces the number of separate interfaces required to complete the workflow; this describes the architecture, not a measured productivity gain.

Scope & limits

From a ticket to the surrounding operation.

The screenshots demonstrate an operations dashboard, ticket register, planned maintenance visits, and spare-parts catalog. Together they show the scope beyond a single CRUD screen. The repository link provides an additional way to inspect the work.

No before-and-after timing, adoption, or commercial results are published in this case study. Its evidence is the implemented functionality and the visible application screens.
