Description
The client wants to document and plan the physical cable routes, corridors, and lines of a typical former telecommunications monopoly on the ESRI platform. This involves mapping various technologies: copper, fiber optics, and hybrid network structures. The ideal candidate would be a consultant who has already developed or designed such systems several times and knows most of the pitfalls from experience. This isn’t about a "simple" pure fiber network, but about complex structures involving multiple technologies. The consultant should help prevent the internal development team from repeating mistakes others have already made. This saves time by guiding them toward "best practices". For example: the client wants to develop a custom model for representing nested cable structures. If a cable corridor is in concrete, it should be displayed differently than a cable in a conduit in sand. This data isn’t stored in the ESRI database but is kept externally (MS SQL Server). The consultancy should speed up the process of using this data in the best possible way. Note: this is not about consulting on ESRI-based third-party products or plug-ins. The client wants to avoid those license costs and build a system tailored specifically to their needs. Environment: The client uses a .NET environment with BLAZER. Development is based on the ArcGIS SDK and web functionality is implemented in JavaScript. MS SQL Server serves as the database. Objectives: the consultancy should answer questions or challenge concepts the client has developed in the examples above.
- Point of contact for ESRI development team projects and problem solving
- Challenging ideas from the development team and offering own implementation ideas (questions range from platform installation and usage to developer concepts)
- Taking responsibility as an independent ESRI consultant (not as a developer)
Requirements
- Deep expertise and experience in documenting and planning telecommunications networks
- Many years of expertise with ESRI tools (5-10 years)
- Excellent consulting skills
- Sporadic availability on customer request (not a full-time project)
