👋 About

Me

Sebastian

I’m a Full-stack Software Engineer with experience designing and building systems from the ground up.

At NerdWallet, I designed and built a Data Change Event caching system (Go, Terraform, DynamoDB, SQS) processing 1-10 million events daily to reduce debugging time for User Ops. At Miva, I developed a Python microservice integrated with a Laravel application to model phone queue behavior and optimize call agent scheduling, reducing customer wait times by 10%.

While in college, I founded JsonPDF, a developer tool for converting JSON data to PDF documents (React, Node.js, MongoDB) with help from USF’s Student Innovation Incubator and the NSF I-Corps program, earning me Tampa Bay Inno’s 25 Under 25 award.

I’m currently seeking a full-stack or back-end software engineering position where I can leverage my skill set to advance a meaningful mission.
