Software engineer on SILBERTEX, delivering a textile production system with AI-directed development.

On SILBERTEX, a production management system for a textile manufacturer, I turned evolving client requests into shipped features for tracking orders, technical sheets, cutting, and sublimation.

I delivered the system end to end with a TypeScript and Node.js backend, PostgreSQL, and a React frontend. I used Claude Code to direct implementation, then reviewed and tested agent-generated code before release.

I migrated the client’s data from SQLite to PostgreSQL and moved legacy spreadsheet records into the relational database through 30+ import and cleanup scripts. I also automated ingestion from email, PDFs, and Excel/CSV files.

At UTN, I worked on academic projects including a Python interlibrary loan application with pytest coverage and a Java car catalog ORM using Hibernate/JPA and JUnit 5.
