Our rapidly-growing software development company needs a user-friendly, feature-rich Project Management System (PMS) to streamline our team's agile development process. The PMS should provide real-time project tracking, task management, collaboration tools, and integrate with our existing Git repository and JIRA instance. It should enhance our team's productivity, visibility, and efficiency.

The PMS should include features such as:

* **Task Management:** Create, assign, prioritize, and track tasks with estimated time and effort
* **Project Tracking:** Real-time project dashboards with customizable progress views and task dependency management
* **Collaboration:** Centralized platform for seamless communication through comments, attachments, and threaded discussions
* **Agile Support:** Support for Scrum, Kanban, or hybrid methodologies with customizable sprints, iterations, user stories, and tracking of velocity
* **Reporting:** Comprehensive reporting and analytics to track team performance, identify trends, and improve processes

The PMS should be highly secure, scalable to support our growing team, and provide a user-friendly interface optimized for desktop and mobile access. It should integrate seamlessly with our Git repository and JIRA instance using REST APIs.
