About Me

Hritik Singh

Data Engineer · Boston, MA

I'm a Data Engineer with 3+ years of experience designing scalable data pipelines across AWS and Azure. My work has ranged from real-time streaming systems processing 1M+ events per week to enterprise ETL platforms handling 50M+ records monthly at Chevron.

Currently exploring where classic data engineering meets modern AI — building RAG systems, LLM-powered data tools, and agentic workflows. Long-term I'm heading toward ML engineering, with data infrastructure as the foundation.
