Hi I'm Cory!

Data-focused Backend Engineer

About Me

I’m a data-focused backend engineer with a strong foundation in database design, data modeling, and building systems that transform and serve data at scale.

My work centers on designing efficient data pipelines, structuring relational and NoSQL databases, and exposing data through clean, reliable APIs. I’ve built systems using PostgreSQL, MongoDB, and AWS-based workflows, focusing on query performance, data integrity, and practical, production-oriented design.

While I have full-stack experience, my primary focus is on the backend and data layer where system architecture, data flow, and long-term scalability matter most. I’m particularly interested in roles at the intersection of backend engineering and data engineering.

Academic Background

I graduated from Rochester Institute of Technology with a B.Sc. in Individualized Study in May 2025, where I designed a curriculum centered on software development, database systems, and backend engineering. My coursework and projects emphasized data modeling, system design, and building reliable, data-driven applications.

Technical Focus

I build backend infrastructure and data systems, with full-stack experience used as supporting depth.
