Backend Developer at Estilo Hogar who developed Java microservices for electronic invoicing and customer notifications.

At Estilo Hogar, I developed Java microservices for electronic invoicing through ARCA/AFIP and for SMS and OTP notifications. I also developed the point-of-sale system and its transaction, inventory, billing, and payment logic.

I built data integration pipelines and scheduled batch tasks, and worked on deployments with Docker and Jenkins. Earlier, at Claro / Ar Consultores, I developed Java systems for network monitoring and sales activations, including Oracle integrations and technical reporting.
