Networking and distributed system integration

Where this work fits

I have designed network infrastructure connecting engineering systems and worked across the application and network layers to troubleshoot connectivity. That experience spans L2/L3 networking, TCP/IP, UDP, routing, VPNs, WireGuard, segmentation, and distributed connectivity across Windows and Linux. Bringing network design and application integration together helps distinguish a routing problem from an interface or configuration problem and gives connected systems a clearer path to reliable operation.

Problems I work on

• An application expects peers to communicate, but routing and configuration assumptions are implicit or distributed across several systems.
• Remote connectivity is needed without treating access to one service as access to an entire environment.
• UDP communication, VPN configuration, and segmentation are being considered separately even though their behavior needs to work as one system.

How I approach the work

• Describe the endpoints, traffic direction, addressing assumptions, and intended access boundaries before selecting or changing network configuration.
• Distinguish application behavior from L2/L3 reachability. A working network path and a correctly configured application are separate requirements.
• Use routing, VPN connectivity, and segmentation deliberately, keeping the allowed communication paths understandable rather than accumulating unexplained exceptions.
• Trace connectivity across Windows and Linux, checking application configuration, transport behavior, and routing before changing the architecture.
