✶ about me

I turn messy human problems into scalable, data-driven software, and I sweat the small stuff.

My path into engineering ran through international communication and learning design, a background that taught me to translate fuzzy human needs into clear systems. Today I focus on backend architecture, full-stack development, and data systems, currently deepening it through a Master's in Computer Software Engineering at Northeastern University.

Recent work spans scalable APIs, faster database queries, responsive React interfaces, and event-driven services on AWS. I'm happiest on problems that pull me across the whole stack, from system performance down to the tiniest interaction.

If you're building something ambitious in software or product, let's make something.
