At Konex Innovation, I developed ONJ's hybrid web and mobile application for Baloto, MiLoto, and Colorloto sales and histories. Using Spring Boot, Ionic, Oracle, and Docker, I optimized queries and deployment to reduce access times by 40% for more than 5,000 monthly users.
I also integrated PayU, SuperPay, and MercadoPago into online sales, enabling end-to-end transactions without manual intervention. I implemented automatic purchase ticket generation with JasperReports and a back office for draws and prize reviews, reducing operational errors in the prize process by 60%.
At Digiteyes, as a freelancer, I built a document extraction web application with AWS Textract and Python (Flask) that processed 100 to 300 files simultaneously and generated Excel reports from configurable templates. I also developed a custom downloads module with Node.js (Express), Angular, and MySQL, supporting more than 500 monthly processes and improving workflow efficiency by 30%.
At SENA, I train groups in Java with Spring Boot, Angular, and relational and NoSQL databases, using practical exercises and supporting final projects. Earlier, I migrated an application for clinical records from Visual FoxPro to PHP (Laravel) and Angular at SAI Soluciones Informáticas, reducing consultation times by 50%.
