Terabyte Dashboard — Automated Internal Reporting System
Terabyte Dashboard is a Full Stack application developed for internal company use, designed to centralize and automate the generation of reports and analytics from multiple corporate systems. The project was fully designed and implemented end-to-end, ensuring data integration, security, and scalability to support different business areas. On the back end, I built a GraphQL API using TypeScript with ETL routines, custom authentication, and role-based access control. On the front end, the application was developed with Next.js, providing user management, internal feedback features, and report visualization with customized, exportable charts tailored to the company’s needs.

TeraDoc — Safety Documentation Management System
TeraDoc was developed to address a client’s need to modernize a legacy system by migrating to a more modern, efficient, and scalable solution. The application enables the registration of company-produced components and dynamically generates safety reports and documentation based on this data. The system was built on top of Next.js, using libraries such as TanStack Table to deliver editable tables and forms that streamline the creation of customized documents. In addition, I am developing decoupled microservices for specific tasks, including a dedicated service for PDF document generation using Python, ensuring flexibility and long-term scalability.

Instagram Clone
This personal project was developed to explore and integrate multiple technologies by recreating a complex application inspired by Instagram. The platform replicates the interface and core features of the social network, allowing users to create image posts, like and comment on content in real time. The application includes authenticated user profiles using Clerk for login and access control, along with Firebase for cloud data storage and synchronization. This architecture enables real-time content publishing and viewing, reinforcing best practices for modern, scalable, and user-focused web applications.
