Project for CLOSE UP through Big Analytics:- Automation of background processes: Implemented a background service that monitors predefined directories, converts images to base64 format, and sends them to a REST API. The system automatically retries in case of connection failures, ensuring the delivery of images without manual intervention, even in scenarios with intermittent connectivity.- Dynamic and customizable configuration interface: Designed a configuration interface that allows users to store branch configuration data in an encrypted file, specifying the directory where the background application processes the images.- Interactive Tray App: Developed a Tray App accessible from the Windows taskbar, enabling users to interact with the application, receive notifications, and quickly access essential settings, keeping the service accessible but discreet.- Robust error handling and retry management: Implemented advanced retry logic to ensure data integrity in case of connection failures. The service queues images until the connection is restored, ensuring that no images are lost.- Simplified and robust installation process: Created an installer using Windows Installer, packaging the application to ensure a simplified installation and configuration process for end users, with no need for technical intervention.- Secure and efficient collaboration with REST API: Managed communication between the application and a REST API, ensuring that processed images were transferred securely and efficiently to an FTP server, guaranteeing a reliable and optimized data flow.

Project for MAMPA through Big Analytics:- Full platform web development from scratch: Designed and developed a web application in .NET 8, divided into a Frontend and Backend (API) connected to a PostgreSQL database. The platform was built to be scalable, secure, and modular, adapting to different user roles with controlled access to modules based on permissions.- Advanced user and role management: Implemented a user management system with specific roles. The administrator role can manage users, assign roles, and define permissions. When a new user is created, an automatic email is sent, allowing them to set up their initial password.- Image processing and advanced product search: Developed functionality allowing users to upload an image converted to base64 format. This image is sent to an external API that returns similar products. The resulting product list can be filtered based on various criteria such as color, size, brand, country, and price range.- Product detail view: When a specific product is selected, the system displays key details like completed sales, available inventory, and other relevant metrics, providing a comprehensive view of the product’s performance and availability.- Responsive web interface development: Utilized Bootstrap, HTML, CSS, and JavaScript to create a fully responsive web design, ensuring that the application functions seamlessly on any device, improving accessibility and user experience.

Project for INTCOMEX through Big Analytics:- Development of a New Complete Module: Responsible for the design and development of a comprehensive module in an existing system, covering both the Frontend and Backend using the MVC model of .NET Core 2 and SQL Server as the database. The project included creating a relational model that supported business logic and developing Stored Procedures for data manipulation.- Development of Dynamic and Responsive Web Interfaces: Implemented MVC views using Bootstrap, CSS, JavaScript, and jQuery, ensuring a responsive and interactive user interface. The controllers developed consumed Stored Procedures in SQL Server, which contained the business logic needed for data interaction.- Bulk Data Loading and Normalization: The main functionality of the system was bulk data loading, handling Excel files that were processed and normalized in the designed database. This allowed for data reconciliation from various sources along with the data loaded from Excel, and generated reports that clearly summarized the reconciliation results. I worked with large volumes of data, optimizing both system performance and accuracy.- Agile Collaboration and Version Control with Gitflow: Worked closely with an agile team under the Scrum methodology, presenting weekly progress and maintaining clear documentation of changes and new functionalities. Used the Gitflow workflow in Bitbucket for version management and source code control, ensuring efficient continuous integration.
