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.

ArmotuSitio 2.0 is my flagship business software project: an actively developed, modular platform that brings operational workflows, customer management, and project delivery into a unified experience.
Product and business scope
- CRM and commercial operations: customer records, leads, budgets and quotations, service/product management, and business follow-up.
- Work management: epics, projects, issues and tasks; Kanban boards, backlogs, sprints, dependencies, rich-text editing, and attachment workflows.
- Operational modules: appointments, scheduling, coordination, customer interactions, and integrations designed around practical business needs.
- Governance and administration: roles and permissions, auditability, validation, and tools for running business processes consistently.
Engineering and architecture
- Frontend: Next.js, React, TypeScript, responsive backoffice interfaces, and static-export deployment where required.
- Backend and data: PHP service/API layers, MySQL, modular responsibilities, and structured business data.
- Security: role-based access control, protected sessions, CSRF defenses, optional two-factor authentication, and authorization boundaries.
- Delivery: automated testing, CI/CD, integration workflows, maintainability, and incremental releases.
- Experience: multilingual content (ES/EN/PT), accessibility considerations, and responsive UX.
This is ongoing product development, not a claim that every planned module is already commercially available. The source code is private; the product and technical experience are documented without exposing confidential implementation details.

| Principle | What it means in practice |
|---|---|
| Production first | Failure paths, permissions, data integrity, logging, and deployment are part of the feature. |
| Clear boundaries | Controllers stay thin; services own business rules; repositories own persistence. |
| Incremental delivery | Small, backward-compatible changes are easier to verify, release, and operate. |
| Product thinking | Architecture decisions connect to the customer, operator, and business outcome. |
I am open to Backend and Full Stack Software Engineer opportunities, as well as relevant software product consulting work.
