Simone Park

Simone Park leads network and connectivity diagnostics at DevicePrep. She builds the browser-based tools—Ping Test, Upload Speed Test, and Network Test—that measure the numbers behind call quality: latency, jitter, packet loss, and upload bandwidth. She also writes the troubleshooting guides that help people improve their connection before joining Zoom, Teams, or Google Meet.

Simone's focus is the network layer of video call quality. She covers Wi-Fi instability and band selection (2.4 GHz vs. 5 GHz vs. 6 GHz), latency and jitter diagnosis for real-time media, upload bandwidth requirements for HD and screen-share sessions, VPN and proxy impact on call performance, router congestion and Quality of Service (QoS) prioritization, and the gap between a speed test that looks fine and a call that stutters.

Before DevicePrep, Simone worked as a front-end engineer on a telehealth platform where call reliability was a patient-safety concern, not just a convenience issue. She learned firsthand that a network can pass a download speed test and still fail a video call—because real-time media cares about jitter and packet loss, not just throughput. That experience drives how DevicePrep's network tools are designed: they measure the specific metrics that affect calls, not just raw speed.

At DevicePrep, Simone designed the Ping Test to surface latency, jitter, and packet loss in a single run, and the Upload Speed Test to show whether upstream bandwidth is sufficient for outgoing video. She built both tools to run entirely in the browser with no plugins or uploads, so users can test quickly without privacy concerns.

Every network troubleshooting guide she writes follows a systematic pattern: measure a baseline with the diagnostic tools, change one variable (move closer to the router, switch Wi-Fi bands, pause a download, try ethernet), then re-test and compare. She's deliberate about teaching the method, not just the fix, because network problems recur and users need to isolate the cause each time.

Simone also tracks how meeting apps adapt to poor networks—Zoom's bandwidth negotiation, Teams' dynamic bitrate adjustment, Meet's fallback to audio-only—so the guides can set realistic expectations. When a user's upload is 1.5 Mbps, she doesn't just say 'get faster internet'; she explains what that bandwidth means for video quality and what settings to adjust in the meeting app to keep the call stable.
