About
I'm Duleep β I Turn Network Complexity into Clarity
I've spent years working deep in the trenches of IP networking, mobile packet core, and IT infrastructure β the kind of environments where a misconfigured route or an undetected anomaly can affect thousands of users. That experience pushed me to go beyond just fixing problems and start building tools, automations, and systems that prevent them.
Today I work at the intersection of networking and software engineering β helping teams automate what's repetitive, visualize what's invisible, and make smarter decisions faster. Whether you need a consultant to untangle a tough network issue, a developer to build a custom tool, or someone to help your team level up, I'm here for it.
What I Work On
- IP/MPLS, Mobile Core, and Fixed Wireless Network Design, Planning, and Troubleshooting
- DevOps and System Engineering using Linux, Docker, APIs, and Workflow Automation
- Software Development using C, C#, Python, and PHP for Engineering Solutions
- AI/ML-driven Operational Intelligence, Anomaly Detection, and Alarm Correlation
- Automated Network Visualization and Dynamic Topology Diagram Generation
- Automated IP Address Management (IPAM) and Network Inventory Systems
- Web-based Engineering Portals, Dashboards, and Custom Tool Development
- End-to-end Automation Solutions for Network and IT Operations
