Bio

Víctor has been working with GIS software for more than 15 years. He has worked on various projects, from driving and developing mainly geospatial components at Xarvio to leading the development and training of a dissemination platform for FAO or developing websites with the latest technology. Along that ride, Víctor has adapted to working in teams ranging from one or two people to dozens, organizing across different subteams, and being productive while working with different technologies.

Work Experience

GIS Software Engineer

2018 - 2022
Xarvio
  • Designed and developed a multistep geoprocess to convert satellite imagery into classified vector data ready to be visualized, including coding specific steps from scratch with GeoTools and JAI.
  • Built and deployed high-availability microservices for obtaining data from multiple sources, processing, and publishing it meaningfully so users can understand their fields better, make decisions, and plan tasks based on that information.
  • Built a library of added functionality, fixes, and abstractions on top of GeoTools to be used by virtually all the microservices in the project.
  • Performed geospatial data migrations regularly with zero downtime.
  • Deployed GeoServer in a horizontally scalable setup with Kubernetes, enhanced by a Sidecar Spring service with REST endpoints to act on the GeoServer data and catalog directly.
