About me

Satellite scanning the Andes

I work at the meeting point of research and full-stack software development, at Universidad Nacional del Altiplano (FINESI) in Puno, Peru — 3,827 m above sea level.

  • Research & development — machine learning on Sentinel-2, Landsat and NASA data for frost, glacial-lake floods (GLOFs), water quality and astrophysics, always with open, reproducible code
  • Full-stack software — I design, build and self-host institutional systems end to end: backend, frontend, database and server
  • Core languages — Rust · Java · C++ · Node.js · TypeScript; backends in Spring Boot, Jakarta EE, .NET, Express, Django and Laravel
  • Cross-platform apps — desktop and device tools that run on macOS, Linux and Windows
  • Open-source frameworks — JxMVC and Cero, Java web frameworks with zero runtime dependencies
  • Publications — 6 published and 3 accepted — J. Astrophysics & Astronomy, SoftwareX, World J. Environmental Biosciences, IJACSA, Informatica and Springer proceedings; 7 more submitted or under review, three of them to Scopus Q1 journals
  • Production — 10+ apps running on my own Linux VPS · andre.net.pe
  • Setup — Arch Linux (Hyprland + Kitty), macOS and Windows
  • Always with the CR7 mentality — "work beats talent"
