At WebEngage, I ship catalog and recommendation-platform features across React, Redux, Java, REST APIs, and distributed data systems. I cut 2M-row catalog refresh time from 71 seconds to 17 seconds through incremental delta sync, then reduced write latency another 10–20% by removing an intermediate staging path.

I rebuilt WebEngage's catalog module end-to-end, including ingestion workflows, virtualised listings, re-mapping, audit history, and live recommendation collection editing with impact previews. I also fixed a scheduler concurrency race affecting recurring imports.

Previously at Zeta, I led Vue 2-to-Vue 3 and JDK 8-to-JDK 17 migrations, reduced frontend regressions by 25%, and raised backend test coverage from 21% to over 90%. I also built a brain tumor detection model that achieved 94% accuracy using Python, TensorFlow, Keras, OpenCV, GLCM features, and an ANFIS-based classifier.
