Hi there, I'm Neha!! πŸ‘‹

Transforming Raw Data into Real-World Solutions

About Me πŸ‘©β€πŸ’»

Hey there! I’m Neha, a Data & ML Specialist who finds joy in uncovering stories hidden within data. ✨🌷

I’ve spent 3+ years designing data pipelines, building ML models, and transforming raw data into meaningful insights. I recently earned my Master’s in Applied Data Science from San JosΓ© State University, where I also served as a Graduate Teaching Assistant for Machine Learning and Distributed Systems.

When I’m not coding or analyzing trends, I’m probably dancing to my favorite tunes or training for my next run - because balance is everything. πŸ’ƒβ˜•πŸ’»

πŸ”­ I'm currently exploring Explainable AI and Foundation Models

πŸ‘― I'm looking to collaborate on ML/AI projects that solve real-world problems

πŸ’¬ Ask me about Data Engineering, ETL Pipelines, Machine Learning, Deep Learning

πŸŽ“ MS Applied Data Science @ SJSU

πŸ’Ό Ex-DXC Technology Data Engineer

⚑ Fun fact: I've analyzed everything from fashion trends to Higgs Boson particles!
