The Challenge

Coosto provides social media monitoring, publishing, and analytics to enterprise marketing teams. The platform ingests firehose-level data, thousands of social mentions per minute, and must surface trends, sentiment shifts, and competitor activity in real-time dashboards. Latency or missed spikes directly impact the value brands get from the tool.

My Contribution

Built the real-time monitoring dashboards that visualized sentiment, reach, engagement, and trending topics as data streamed in. Implemented efficient DOM update strategies to handle thousands of mentions per minute without the UI freezing or falling behind.

Created interactive campaign-performance reports with drill-down charting, enabling marketers to slice data by platform, time range, and sentiment. Worked directly with the PHP backend team to optimize the data API for streaming updates.

Key Results

  • Monitoring dashboards processing 1,000+ social mentions per minute without UI lag
  • Campaign reporting used by enterprise marketing teams for daily decision-making
  • Sentiment visualization enabling brands to catch PR crises within minutes
  • Efficient DOM rendering strategies keeping the UI responsive under heavy data load
