At Ubidots, there was an ECharts widget that took up to 30 seconds to render. Nobody filed a bug report — users just closed the tab. I found it in a DevTools session at 11pm.
I worked as a Senior Engineer at Ubidots, an IoT platform with 150K+ users and millions of real-time events. Outside of code, I'm a speaker, mentor, and published author at IEEE Xplore.
Published research in IEEE Xplore on security in decentralized blockchain systems.
