I am a Backend & Full Stack Software Engineer based in Argentina, focused on building business applications, SaaS products, APIs, and the systems that support them in production.

I work across Go, PHP, Node.js, TypeScript, React, and Next.js, with experience in relational data, authentication, RBAC, cloud infrastructure, observability, and CI/CD. I have worked on both product teams and independent software projects.

I also use AI-assisted development (Claude Code, Codex, skills, and validation workflows) to accelerate implementation while keeping code review, testing, and technical decisions under human control.

Open to Backend and Full Stack Software Engineer opportunities.

• Backend architecture, REST APIs, authentication, RBAC, and business-critical workflows.
• Full stack products, SaaS platforms, e-commerce, backoffices, and internal tools.
• Business automation with webhooks, cron jobs, n8n, queues, and third-party integrations.
• CI/CD, Docker-based delivery, cloud infrastructure, observability, and production support.
• Code reviews, testing, documentation, mentoring, and developer education.
• Infrastructure as code and configuration management with Terraform and Ansible.
• AI-assisted delivery with Claude Code, Codex, reusable skills, and verification workflows.
