Software Engineer at Adora POS, modernizing enterprise POS software used by 1,200+ Marco's Pizza locations.

At Adora POS, I build full-stack features for enterprise point-of-sale software used by 1,200+ Marco's Pizza locations and other national chains.

I develop C#/.NET REST API endpoints for order information and maintain a Docker-based local database environment for safer, isolated development.

I led an Angular proof of concept to evaluate modernizing the legacy front end, and I update legacy JavaScript and .NET code to improve stability and maintainability.

At HCL Technologies, I developed React UI features for Western Union's new digital product and automated operational reporting, cutting report creation time by 60%.
