Built a full-stack monitoring platform that automates ingestion, processing, and visualization of infrastructure metrics from Excel and PowerPoint operational reports, applying OOP design principles across the codebase. Engineered file-parsing pipelines using SheetJS and pptx2json to convert raw Excel/PPT data into structured metrics persisted in MySQL via TypeORM. Developed RESTful APIs in NestJS with JWT-based authentication, role-based access control, and real-time dashboards in React; documented the full system in a 100+ page technical report covering a 68-endpoint API spec and database schema.
