SaaS Platform for On-Site Services Management

Senior Full Stack Developer – Enterprise Business Management Platform

Project Overview

We are seeking an experienced Full Stack Developer to complete the development of an enterprise SaaS platform designed for companies that provide field and on-site services.

The platform is intended to replace multiple disconnected systems by providing a single solution for managing the entire business operation—from customer acquisition to service delivery, invoicing, reporting, and long-term customer relationships.

The application will support multiple independent companies (multi-tenant architecture), each operating under its own branding, users, permissions, and data while sharing the same cloud infrastructure.

This is a large-scale commercial software project that combines desktop, mobile, web, and cloud technologies into a unified ecosystem.
