15 years across Wi-Fi protocol analysis, OTT streaming QA, and broadband gateway qualification. I've spent my career at the layer where the spec meets the hardware — and they don't always agree.

Currently qualifying Wi-Fi 7 gateways — 802.11be, MLO, 320 MHz channels, 4096-QAM. The problems at this layer are genuinely new. I find that motivating.

Before Wi-Fi 7: FiosTV OTT QA on the Synamedia platform. That combination — 802.11 protocol depth plus application-layer QoE — is what eventually became WiFi Analyser.

Expensive tools shouldn't be the only path to protocol-level insight. A good engineer with a free capture tool and deep spec knowledge beats a bad engineer with AirMagnet every time.

When AirMagnet went end-of-life in December 2025, engineers lost their primary PCAP analysis tool overnight. I built WiFi Analyser so no one has to go without. It's free. It will stay free.

Pursuing CWNA-109, then CWAP, then CWNE. Certifications don't replace experience — but they sharpen how you articulate what you already know.
