RODRÍGUEZ MARIANI

Information Systems Engineer · Full-stack & AI-augmented development

shipping Cuonti — 50+ active clients in production · Bahía Blanca, Argentina

cat profile.md

I build and operate production web platforms end to end: from API design to deployment and release management on Linux infrastructure I run myself. Information Systems Engineer, graduated from Universidad Nacional del Sur.

By day I work as a Software Engineer at NexoSmart (Laravel + Next.js). Alongside that, I co-created Cuonti, a multi-tenant tax-automation SaaS used in production by 50+ active clients. Agentic AI tooling — Claude Code in particular — is a core part of how I ship.

Production VPS

Owner & operatorself-hosted

  • Full ownership of the path from merge to production: server config, TLS, releases and rollbacks.
  • Ubuntu
  • Nginx
  • Cloudflare
  • CI/CD

claude config list

Not autocomplete — agentic workflows. I run AI agents as part of my engineering process on real production codebases, with the same rigor as any other code: reviewed, tested and verified before it ships.

Multi-agent workflows

Planning agents, parallel codebase explorers and adversarial reviewers orchestrated on real features — not toy demos.

Custom skills & commands

Reusable skills and slash commands that encode repeatable engineering tasks: design systems, code review checklists, deploy routines.

MCP servers in daily work

Model Context Protocol servers wired into the workflow — project management, documentation and design tools reachable from the agent session.

Verification before done

Every AI-assisted change runs the same gauntlet: builds, tests, lint and a human review. AI speeds up the loop; it doesn't skip it.
