Overview

Telecommunication Network Manager (TNM) is a next-generation web-based SaaS GIS platform built to replace Esri ArcGIS Pro for telecom network planning and engineering.
It enables admins and engineers to model, build, and manage end-to-end network infrastructure directly in a modern web application.

This has been my primary and largest project, and I have been developing and expanding it for over 1.5 years—leading core modules, implementing major features, and shaping its architecture.

Teklabz Telco Network Manager

Teklabz Telco Network Manager (TNM) is a web-based application built on the ArcGIS Utility Network framework, specifically designed to support telecom business processes such as:

Order to Activation (O2A)
Plan to Build (P2B)
Trouble to Resolve (T2R)

TNM offers users a modernized and secure system for creating, editing, analyzing, and sharing network information.

The solution employs a versatile data model that contains comprehensive information about telco assets, including:

Infrastructure network elements like manholes, ducts, and cabinet structures.
Telco network components like cables, patch panels, and ports.
Efficiently manages low-level connections and relationships between these assets, ensuring full visibility of telco network connectivity.

Tech & Integration

Frontend: Developed using TypeScript, React, Tailwind CSS, React Hook Form, TanStack Query, AG Grid, and custom hooks/components.
GIS Integration: Integrated ArcGIS JavaScript API and other GIS APIs as third-party services to power web-based mapping and analysis.
Portal & Services: Leveraged ArcGIS Portal and ArcGIS Server Services for secure data hosting, map services, and utility network operations.

Achievements / Highlights

Built and led core modules: Work Orders, Feature Sketching & Editing, Mass Deletion, Inventory Browser, Model Palette, Association Editor, Connectivity Manager, Tracing Tools, Print Layout, Saved Maps, Admin, and Model Builder.
Collaborated closely with backend and QA team members in an Agile environment to drive feature delivery, coordinate releases, and ensure quality.
Designed and implemented complex telecom data models and workflows (such as units, splices, trays, strands, ports, and chassis) using TypeScript’s discriminated-union and generic typing patterns to ensure strong type-safety and maintainability.
Solved complex operations like feature deletion and large-scale child/associated feature removal by designing and discussing solutions with the team.
Successfully integrated ArcGIS Portal and ArcGIS Server Services for seamless third-party GIS data and services consumption.
Acted as the main developer from the early stages, helping bring the product to life and drive it forward through multiple releases.
Delivered deployments for international customers, including custom features and configurations to allow them to test, evaluate, and adopt the platform.
Added numerous customer-specific features and customizations to meet different telecom operators’ workflows and compliance requirements.
Contributed to continuous improvement of the platform’s performance, security, and scalability to support production deployments.
