Luis Saenz

Who am I?

Double degree in Computer Science and Mathematics, Universidad Autónoma de Madrid. Erasmus year at TUM Munich.

I am in my final year of the double degree and I cannot leave alone what sits underneath: I wrote an MNIST classifier in NumPy before touching PyTorch, and the server this page runs on is mine to look after. I am after an internship where I can keep building things like that.

MNIST classifier in NumPy

95% test accuracy

A neural network written from scratch. Forward pass, backpropagation and gradient descent implemented by hand with NumPy, no frameworks involved, to understand what every operation does before delegating it.

Automatic driver assignment

Technical design and MVP

A proposal for the transport company MoMo: first a technical analysis and design document, then a Python MVP. The algorithm matches drivers to jobs while minimising the total cost of the assignment.

Home server

Self-hosted at home

The machine serving this page. Linux and Docker containers for everything running at home: Immich for the photo library, a NAS for backups and a reverse proxy with HTTPS in front plus other services.

  • Linux
  • Docker
  • Nginx
No public repository

Utilities

Utility programs I use.

Claude Code skills

My own instructions teaching the agent how I work: how to review code, how to deploy to the server, and a tutor mode that explains instead of solving.

  • code-review

    Reviews a diff for real bugs before touching anything about style.

    wget https://raw.githubusercontent.com/LSM-git/claude-skills/main/code-review/SKILL.md

  • deploy

    Automates deploying this portfolio to my home server.

    wget https://raw.githubusercontent.com/LSM-git/claude-skills/main/deploy/SKILL.md

Utility scripts

Short command-line programs for what I repeat every week: server backups, clearing downloads and spinning up work environments.

  • backup.sh

    Copies the server’s databases and Docker volumes to the NAS.

    wget https://raw.githubusercontent.com/LSM-git/scripts/main/backup.sh

  • clean-downloads.sh

    Sorts and clears out what has been piling up in Downloads for weeks.

    wget https://raw.githubusercontent.com/LSM-git/scripts/main/clean-downloads.sh

Dotfiles

My Linux setup under version control — window manager, terminal and editor — so a fresh machine is ready in minutes.

  • hypr/

    Window manager configuration: keybindings, animations and monitors.

    wget https://raw.githubusercontent.com/LSM-git/dotfiles/main/hypr/hyprland.conf

  • nvim/

    Neovim configuration: plugins, keymaps and LSP settings.

    wget https://raw.githubusercontent.com/LSM-git/dotfiles/main/nvim/init.lua
