I'm Vaibhav Haldia. Full-Stack AI Engg. & Data Scientist Building production systems through code and data.
Projects
Full-stack primary research platform — mobile survey instrument (React Native/Expo, 5 question types incl. NPS) → FastAPI ingestion pipeline with Pydantic data contracts, Great Expectations validation, and Celery async aggregation. Analytics layer runs KMeans respondent segmentation and scipy significance tests on every response batch. Tableau dashboards (NPS trend, segment profiles, demographic crosstabs, response heatmap) connected directly to PostgreSQL.
