Featured Projects
Asadero Diez: Order and Automated Marketing Platform
Development of a comprehensive platform for the 'Asadero Diez' restaurant, featuring an interactive landing page with the menu and an online ordering system (without direct payment processing). We implemented robust process automation using n8n for order management and deseek for decision analysis. After each order, both the restaurant and the customer receive detailed notifications via WhatsApp. Additionally, we integrated a bot that allows restaurant staff to update order statuses, automatically notifying customers about their order's progress.
Secure E-commerce Platform for Restricted Security Environments
Creation of an innovative e-commerce platform designed for correctional facilities, enabling inmates to order products from tablets located in common areas. The system includes a back office for guards to approve or reject orders based on inmate behavior. We implemented an advanced inventory system with unique QR codes for each product, facilitating tracking and management. The QR scanning functionality, using the device's camera, allows for real-time inventory updates and verifies waste return to confirm the product is no longer in the inmate's possession. A clean architecture was used to ensure system maintainability and scalability.
Automated Web Data Extraction and Academic Certification System
A university project focused on automated data extraction from their existing web system. We developed a backend capable of authentication and session management (cookies) using Puppeteer to access student grade information, as the university's system did not expose a public API. The main goal was to process this information to generate Excel files with specific formats required by the university and create PDF 'grade reports' that serve as academic certifications. The implementation followed a clean architecture to ensure process efficiency and scalability.
AI-Powered Enterprise Sales Analytics Chatbot
Development of an intelligent chatbot designed to provide detailed information about a restaurant's orders and sales within specific timeframes. Similar to models like Gemini or OpenAI, this chatbot uses artificial intelligence capabilities to interpret data requests, including generating charts and tables. By leveraging OpenAI's 'tools' or 'functions,' the bot can execute complex operations and present precise visual analyses to optimize sales-based decision-making.
