CellCloud

Battery telemetry at scale, queried in under 30 seconds.

Role
Architect and lead engineer at Igknight Tech

Overview

Architected a battery-data visualization platform on Python and Flask, built to explore datasets far past the point where a naive query plan gives up. The work was equally about the query layer and the live layer: analysts needed both history and a view that updates while they watch it.

What I built

  1. Architected the Python/Flask visualization platform
  2. Implemented real-time data streaming over WebSockets
  3. Optimized AWS Athena queries across massive datasets
  4. Brought load times under 30 seconds on the heaviest views
