Vedanth Prasanna Bharadwaj

Backend & Cloud Engineer | Data & ML Engineer

I build scalable backend systems, AWS serverless architectures, data pipelines, dashboards, and machine learning solutions. My work combines cloud engineering, SQL optimization, data observability, and applied ML.

About Me

I am a backend, cloud, and data-focused engineer with a Master of Science in Data Science, Analytics & Engineering from Arizona State University. I currently work on production-grade AWS serverless systems at MindSpark, with hands-on experience across AWS Lambda, API Gateway, Step Functions, Aurora PostgreSQL, RDS Data API, AppConfig, SQL optimization, Power BI, and machine learning pipelines.
