Bengaluru, India
Auxia
AI Research Engineer (Applied Scientist)
  • Built two standalone treatment embedding pipelines (OpenAI + SBERT) with enriched metadata, improving downstream target prediction accuracy by ~12% and enabling client-specific flexibility via Metaflow infra.
  • Prototyped behavioral segmentation using LLM-generated user summaries from multi-signal event logs (clicks, views, dwell-time), uncovering latent user groups and boosting CTR prediction accuracy by ~9%.
  • Led uplift modeling and causal A/B testing using funnel/binning analysis to identify high-lift segments; applied suppression/force-send rules to optimize personalized targeting.
  • Automated and standardized ML training workflows with pipeline orchestration tools, reducing manual coding by 50% and cutting training time by ~25% with cron-scheduled production deployments.

Pune, India
HiLabs Xtra Miler Award
Machine Learning Engineer II (Senior AI Developer)
  • Leveraged diverse generative and encoder LLMs (T5, BioBERT+CRF/LSTM, Mistral, LLaMA) for clinical entity recognition from medical charts, achieving 95% F1 in structured extraction of drugs and diseases.
  • Optimized inference via model distillation, layer freezing, and mixed-precision inference, reducing end-to-end extraction time while preserving entity-level precision for safety-critical medical data.
  • Led a team of 6 engineers building entity extraction and downstream RAG-based QA systems for healthcare clients using medical charts and Google search results.
  • Designed a multi-class webpage classifier (93% precision) using BERT embeddings with XGBoost, incorporating hyperparameter tuning.
  • Spearheaded the Provider Directory Accuracy product to improve HEDIS scores for U.S. health plans, driving Fortune 500 adoption and increasing ARR from $11M to $39M.
  • Automated web scraping with spaCy NER and proximity search to extract provider data; designed knowledge-graph pipelines and Spark jobs for large-scale analysis.
