Full Stack Developer with Software Architecture training

Full Stack developer with a specialization in Software Architecture (TECSUP). I work mainly with Java and Spring Boot, Python and TypeScript (Angular, React).

At CorAll D&R I build products and custom systems for clients: a parking SaaS, ERP modules, e-invoicing, and WhatsApp automations with AI agents.

Before that I freelanced for an NGO and a therapy center, and at university I built computer vision projects and multi-agent systems.
