Basic Info

I work as a senior software developer, system architect, and technical educator. This role draws on more than 35 years of experience across software development, infrastructure engineering, and university teaching. The result is:

  • Comprehensive understanding of the full technology stack, from frontend applications through backend services to underlying infrastructure
  • Practical ability to design, build, automate, and maintain production systems end-to-end
  • Capacity to communicate complex technical concepts with clarity — refined through two decades of university instruction

Benefits from This Experience

  • Purpose-built internal tools that translate intricate domain workflows into effective, usable software
  • Automated, reproducible infrastructure that accelerates provisioning and eliminates configuration drift
  • Robust GNU/Linux server and network environments, seamlessly integrated with heterogeneous systems
  • Thorough documentation and structured knowledge transfer — teams gain autonomy, not dependency

Summary
35+ years in IT, software development, and infrastructure
25+ years teaching at universities (3 institutions, 6+ courses)
10+ years in the energy sector (SCADA, grid optimization)
300+ managed desktops provisioned and administered
350+ users supported on SCO Unix and GNU/Linux application servers
$100M+ in annual customer savings attributed to grid reconfiguration work
4 sectors served: energy, government, education, private consulting
2 languages: Spanish (native), English (professional working)

Major Achievements

  • Helped build the analysis platform at NewGrid that power systems engineers use to identify grid reconfigurations and study their impacts — work that has contributed to over $100 million in annual customer savings in the U.S. Midwest (World Economic Forum)
  • Introduced Infrastructure as Code practices using Ansible within a provincial government organization, establishing the first IaC environments from the ground up
  • Engineered custom Debian installation media that reduced desktop provisioning from 2–3 days per machine to 5 simultaneous installations in 2 hours
  • Migrated a 50-user Microsoft Windows file server to a Debian-based Samba server architected to support 300 users
  • Scaled IT infrastructure to over 300 managed desktops distributed across multiple government buildings
  • Established the first online Internet access and the first public-facing web server at a university campus
  • Designed and deployed the first intranet at a provincial power utility serving 350+ users
  • Founded and directed an IT consulting firm delivering open-source solutions to clients in maritime transport, education, manufacturing, and services

Current Focus

  • Designing and maintaining an internal analysis platform used by power systems engineers to investigate grid congestion and recommend transmission reconfigurations
  • Developing specialized tooling for highly qualified electrical engineers with deep expertise in grid operations and electricity markets
  • Collaborating with domain experts to translate complex power systems workflows into well-structured software solutions
  • Teaching programming paradigms (Smalltalk, Scheme, Prolog) at Universidad Tecnológica Nacional — 25 years and continuing

Skills

  • Full-stack software development spanning modern frontend technologies (Vue.js, TypeScript, Vite) and backend services (Python, Flask, PostgreSQL), with a focus on building internal tools for domain specialists
  • System architecture and infrastructure design, from bare-metal GNU/Linux servers to cloud deployments on AWS, Digital Ocean, and Tektonic
  • Infrastructure automation and configuration management using Ansible and Terraform, encompassing fleet-wide convergence and reproducible development environments with Vagrant and Docker containers
  • Network services engineering: DNS, DHCP, firewalls, web proxies, mail servers, backup systems (Bacula), and VPN
  • Data visualization and interactive analytical dashboards using D3.js, Chart.js, and Leaflet for geospatial representation
  • Heterogeneous environment integration across GNU/Linux and Microsoft Windows platforms, including file services (Samba), messaging, spam filtering, and vertical business applications
  • Technical instruction and curriculum design for university courses and professional workshops, with a sustained ability to convey complex systems with precision and clarity
  • Energy sector domain expertise spanning SCADA software evaluation, grid congestion analysis, and transmission topology optimization
