πŸ‘‹ Hi, I'm Yamini

A data and software-focused engineer ,Master's in Data Science @ UMass Dartmouth

I build reliable, scalable systems that solve real-world problems and create measurable impact. My work lives at the intersection of data, backend engineering, and analytics, where I turn complex datasets into production-ready systems that enable better decision-making, automation, and customer experiences.

I’ve delivered end-to-end solutions across multiple domains β€” from backend data pipelines and APIs to experimentation frameworks and analytical services powering sentiment analysis, recommendation systems, and workflow automation. I enjoy owning problems from design through implementation, with a strong focus on performance, correctness, and scalability.

I’m currently open to opportunities in Backend Data analytics, Data Engineering, Data Science and Software Engineering, and I enjoy collaborating on impactful projects, exchanging ideas, and building data-driven, engineering-led products.

Always excited to collaborate on data-driven products and scalable engineering πŸš€
