Data scientist
with purpose

I turn complex datasets into meaningful insight — whether that's predicting bus seat sales across 14 routes, modeling menstrual cycle regularity across 1,660 longitudinal records, or building dashboards that reveal hidden patterns in revenue data.

My work lives at the intersection of human health, behavioral data, and machine learning. I'm particularly drawn to personal informatics: systems that help people understand themselves better through their own data.

Currently completing my MSc at Amrita Vishwa Vidyapeetham, with a minor in Logistics & Supply Chain Management — and preparing my first research manuscript for journal submission.

TaskShift: A Cycle-Aware Task Scheduling System for Personal Informatics

104 Survey N
1,660 Tracked Cycles
4 Cycle Phases

A pioneering framework that integrates menstrual cycle data with personal productivity scheduling — addressing a gap in personal informatics research that typically ignores biological rhythms in task management.

Designed a cycle-aware task management framework integrating menstrual phase data with adaptive scheduling algorithms
Conducted cross-sectional survey (N=104) analyzing perceived energy variation across cycle phases using ANOVA
Performed longitudinal analysis of 1,660 self-tracked cycles to study individual-level regularity patterns
Developed rule-based adaptive scheduling algorithm supported by an energy prediction model
Implemented cross-platform mobile app (Flutter + Firebase) with modular three-layer architecture
