About Tanmay

I am a Data Engineer with several years of experience building and deploying data solutions for clients across different industries. My expertise spans modern data engineering (ETL/ELT, cloud warehouses, pipeline orchestration), software engineering best practices, and the fundamentals of DevOps, allowing me to deliver reliable, production-ready systems.

I have worked on projects involving cloud infrastructures, real-time and batch data pipelines, distributed processing (Spark), and CI/CD workflows. Beyond engineering, my academic background in Data Science allows me to collaborate effectively with Data Science teams, helping operationalize models through robust data pipelines.

Clients value my ability to quickly understand business needs, translate them into technical architectures, and deliver solutions that are scalable, maintainable, and aligned with modern best practices and I enjoy bringing clarity and structure to messy or incomplete data environments.

If you need someone to build reliable data products or improve your existing infrastructure, I’d be happy to help.
