Featured Projects
Sicredito: Digital Credit Fintech Platform
Development of a fintech digital credit platform with SvelteKit/Svelte 5 frontend and Spring Boot backend, covering the full flow: registration, application, verification, disbursement, and collection. Implemented integrations with STP, Openpay, and an identity verification provider, including webhooks, CLABE validation, disbursement logic, and state synchronization. Modules were structured following hexagonal architecture principles, dependency injection, and domain-driven flows.
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.
MalagaIoT: Smart Alarm System with Notifications
Production multi-tenant alarm system that processes MQTT events from ESP32 devices and routes notifications and commands through WhatsApp and Telegram. The Go backend manages device connectivity, detects disconnections automatically, and allows users to control the alarm (arm, disarm, pause) via natural language chat messages. Includes real ESP32 firmware with magnetic sensors, relays, and physical buttons. Deployed with Docker in production.
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.
