@ralrubncolunga

Backend developer at MacroIntell S.A. who cut cloud infrastructure costs by about 25% and deployment steps by 80%.

At MacroIntell S.A., I developed and maintained backend services and REST APIs for TodoAgro and AgroCarteira, including business logic, data processing, and third-party integrations.

I also designed and implemented AWS infrastructure for production microservices. By automating on-demand staging, I reduced cloud infrastructure costs by about 25% and deployment-related manual steps by 80%, while adding centralized logging and distributed tracing.

Earlier at MacroIntell S.A., I developed a web platform for the Faculty of Law of UNNE across frontend and backend, using Next.js, Express.js, TypeScript, and CSS.

My work includes Node.js, TypeScript, AWS, and cloud infrastructure. I hold an Associate Degree in Programming and Analysis from Universidad Nacional del Nordeste and an AWS Certified Cloud Practitioner certification.
