Network engineer and hardware tinkerer with a passion for high-performance infrastructure. From designing BGP topologies and tuning OSPF areas to pulling fibre, deploying RDMA over InfiniBand, and listening to the RF spectrum with SDR — if it has a packet or a signal, I want to understand it.
// 01 — about me
Hey — I'm slowcupcake. My home lab is my playground: a growing rack of switches, servers, and fibre patch panels held together by stubbornness and way too many SFP+ transceivers.
On the networking side I live at the L2/L3 boundary — building VLAN segmentation strategies, tuning BGP policies with route maps and prefix lists, running OSPF multi-area designs, and overlaying VXLAN tunnels across the fabric.
On the hardware side I run RDMA over InfiniBand for low-latency inter-node communication in a multi-node compute cluster, which feeds a Folding@Home distributed compute workload contributing to protein folding research.
When the lab is quiet I'm listening to the RF spectrum with an RTL-SDR or HackRF — decoding ADS-B, pulling NOAA APT satellite imagery, sniffing ACARS, or just watching the waterfall.
