Experience¶
Google Inc¶
-
[Ongoing] Building chat and voice agent for 100K+ 3P advertisers to improve lead nurturing and qualification with custom tools using Gemini, Cloud ADK, Vertex AI (Search grounding), and GTP.
-
Built Search Home page recommendation for Play Store - generated high-quality recommendable queries using Google PaLM 340B model with safety evaluation.
-
Redesigned Play Store suggest (autocomplete) indexing and serving: 200M+ query indices, 20ms p99 latency, personalization model with user signals at 80K QPS (6B+ queries/day).
-
Founding engineer of Android System Intelligence team. Led design and implementation of Universal Search - a new search surface in Pixel Launcher enabling on-device search across installed apps, contacts, settings, screenshots, and files. Designed ranking and indexing architecture balancing low latency, relevance, and privacy. Led the next app-predictions feature using DNN inference on-device. These launches rolled out to 8M+ pixel devices.
-
Built Deep Neural retrieval system with 300M+ question embeddings, serving 10% of web-search with low latency; powers "People also ask" feature enhancing user engagement.
-
Launched several query understanding improvements (synonyms, salient-terms) in web-search ranking with significant IS@5 (Information-Satisfaction) gains.
Yahoo! Research Lab¶
- Keyword extraction from images using unsupervised ML; progressed to IIT Bombay collaboration with research grant support.
