Summary
My background/strengths are in analyzing bottlenecks and inefficiency up and down the stack, and principled, data driven engineering to improve the underlying systems. In the recent past, I have worked on:
1. Improving video streaming on Meta's apps
2. Accelerating web applications and Ad stacks, at scale
3. Large scale, low-cost video delivery on wireless data networks
4. Inferring performance bottlenecks in Tier-1 IP and 4G data networks.
I also have considerable experience in processing large amounts of data through its life-cycle - from ingestion/storage at fiber-link speeds, building aggregation/ETL pipelines and developing inference/analysis techniques.

Senior Staff Engineer
Instart Inc
11.2013 - Current
- Technical lead for flagship features on accelerating dynamic web content (HTML Streaming). Deployed in several hundred customer domains with 100+m page views every day.
- Initiated and key contributor to the real user monitoring (RUM) and A/B testing platform, with industry novel analytics to identify and visualize web-page and Ads stack bottlenecks, and correlate Ad creatives with poor page performance.
- Key contributor to "new initiatives" projects, specifically around Ad stack and header bid acceleration, through a combination of predictive resource prefetching, resource scheduling and service workers as a web-proxy in the browser.
- Miscellaneous engineering projects around scaling the HTML content transformation pipeline, 3rd party cookie virtualization and cookie syncing and customer log delivery.
- Filed and granted several patents, contributed to technical blogs, and mentored employees and interns.
