About
// 01.1 — profile
I transform business problems into fast, scalable digital solutions. Whether working as a full-time engineer or a freelance consultant, I build production web platforms end to end: from API design to deployment. Information Systems Engineer, graduated from Universidad Nacional del Sur.
By day I work as a Software Engineer at NexoSmart, and as Co-founder of Xenova I deliver custom software to real businesses. Agentic AI tooling — Claude, Gemini, Antigravity CLI — is a core part of how I write high-quality code in record time.

// 05 — agent orchestration
How I work
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.
- 5.1
Multi-agent workflows
Planning agents, parallel codebase explorers and adversarial reviewers orchestrated on real features — not toy demos.
- 5.2
Custom skills & commands
Reusable skills and slash commands that encode repeatable engineering tasks: design systems, code review checklists, deploy routines.
- 5.3
MCP servers in daily work
Model Context Protocol servers wired into the workflow — project management, documentation and design tools reachable from the agent session.
- 5.4
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.
