About

Senior SRE and DevSecOps engineer. Twenty years in Linux systems, cloud platforms and blue team security.

Recent work: reliability, observability and high availability across the ingest, packaging and distribution stack for live streaming. Separately, acoustic documentation of geological formations in Salta, Argentina (Latin Grammy Foundation recognition).


Background

Two parallel tracks at the start: music technology at Universidad Nacional de Quilmes and fullstack web development, including the original archive platform for Fundación IDA.

Student work: parsers turning YAML files into MIDI, audio edited with SoX, mixed with Ecasound. The bachelor thesis followed: yml2mid, a portable control sequence player. Command line tooling over captive interfaces for one reason: plain text is version-controllable, automatable, composable and resistant to obsolescence.

Those descriptors remain readable and parseable. Most of the software that produced them no longer runs. The same reasoning, applied to knowledge management.

Postgraduate studies at UTN, Information Systems Engineering: architecture for distributed computing, object-oriented patterns applied to container orchestration, court-admissible digital forensics, ledger technologies, metaheuristics and multi-agent simulation.

Since then: platform migrations, engineer mentoring, reliability targets negotiated against delivery cadence. A 400x throughput gain after redesigning data flow boundaries to remove synchronous bottlenecks. MTTR down over 90% through event-driven alerting, runbook automation and tighter observability loops.


Work

Platform reliability: SLO definition, failover design and incident response for OTT media and distributed workloads. One example: a DASH segment fetching defect generating millions of spurious CDN requests, traced and resolved with backend and edge teams.

Supply chain security: SBOM generation, artifact signing, provenance verification and pipeline hardening.

Cultural: acoustic heritage documentation with GRAPa, sound installations for international festivals, tooling for musical notation.

Open source: MIDI sequencing from text descriptors, a Kubernetes auditor aggregating SBOM and CVE data, publishing pipelines for academic documents.


Recognition

2022 National Innovation Award: Ministerio de Cultura de Argentina and Universidad Nacional de Quilmes, for the portable MIDI control sequence player.

CACIC 2022: Co-authored paper on conceptual modeling of smart cities.

Latin Grammy Foundation: GRAPa acoustic heritage survey.

Docilizador Sonoro v0.3: Sound installation (IN-SONORA, Madrid).

Paredes Hyperactivas: Interactive installation and performance (Universo Paralello #10, San Salvador de Bahía).


Design

Interest in color theory, typography, grid systems and legibility, though the day job is not frontend. The same choices affect comprehension in documentation and architecture diagrams as much as in interfaces.


Current

Based in Pontevedra, Spain. Working remotely.
