Hi, I’m Sneha!

I’m a data scientist and researcher currently pursuing my M.S. in Data Science at Columbia University. I enjoy turning messy, complex data into systems that work in the real world, from research pipelines to production-ready software. Based in NYC.

Work

Graduate Research Assistant — Zuckerman Institute

Sep 2025 – Present · New York, NY

Pandas · Electrophysiology · Feature Extraction · Signal Processing

  • Designed an automated electrophysiology analysis pipeline extracting ~20 signal-level features per cell from injected current and voltage recordings across hundreds of mouse and human cells.
  • Applied signal processing techniques, including peak detection, input resistance estimation, and Savitzky–Golay filtering, to transform noisy biological time-series data into structured, quantitative features.
  • Replaced hours of manual, cell-by-cell analysis with reproducible code, enabling analysis of dozens of cells in minutes and producing ML-ready feature matrices for downstream tasks such as cell classification and maturity indexing.

Systems Engineer — McMaster-Carr

Aug. 2024 – Aug. 2025 · Chicago, IL

Disaster Recovery · Server Architecture · Networking · Cybersecurity

  • Deployed 5 Dell PowerEdge servers into production, supporting company-wide backup and disaster recovery infrastructure and managing ~90% of organizational backups.
  • Led migration of hundreds of PCI-compliant backup jobs spanning multi-terabyte volumes of critical data to a new Commvault environment, executing a zero-data-loss cutover.
  • Reduced backup cutover downtime from ~8 hours to 1 hour by introducing Commvault LiveSync, and authored detailed documentation that became the standard template for future backup migrations and upgrades

Software Engineering Intern — Apple

May 2023 - Aug. 2023 · Sunnyvale, CA

visionOS · SwiftUI · UX

  • Built a focus-oriented mindfulness experience for Apple Vision Pro, developing and testing features directly on-device using SwiftUI.
  • Led the implementation of an attention-aware mindfulness flow that responds to user focus state, gently guiding users back to concentration through adaptive audio cues.
  • Drove user testing and feedback sessions to evaluate engagement and perceived focus, iterating on the experience based on qualitative insights

Software Engineering Intern — Apple

May 2022 - Aug. 2022 · Sunnyvale, CA

iOS · macOS · visionOS · SwiftUI

  • Designed and built an internal 3D asset library to streamline how designers, developers, and testers access and integrate 3D content into applications.
  • Reduced friction in the asset-integration workflow by replacing a previously manual, time-consuming process with a centralized asset management system.
  • Expanded the library across iOS, macOS, and visionOS, increasing adoption and improving productivity for teams focused on content creation.
