MatiasZapf - Overview

`$ whoami`

Software Engineer building a cloud-native B2C/B2B platform with event-driven architecture — high-concurrency workflows, real-time geospatial processing, privacy-first by design.

By day I write Python and TypeScript. By night I study Cyberdefense at Universidad de la Defensa Nacional (UNDEF) — the first undergraduate degree in Argentina dedicated to Critical Infrastructure Protection.

Previously a Programming Instructor at Silicon Misiones, teaching Python for Data Science & AI to 50+ students. That experience taught me that explaining things clearly is just as valuable as building them — a skill I now apply to my technical blog.

`$ cat focus.md`

🔧 Designing reliable event-driven workflows and scalable background processing
🗺️ Real-time geospatial data modeling (privacy-by-design, strict data segregation)
🔒 Applying cybersecurity fundamentals as an engineer, not just a student
✍️ Bridging computer science concepts with practical security applications on zapf.dev

🔒 Stealth-mode SaaS (in progress)

Cloud-native platform built from scratch — event-driven, geospatially-aware, privacy-first.
Stack: FastAPI · Next.js · PostGIS · Celery · Redis · AWS. More details when it ships.

🌐 zapf.dev

Personal website and technical blog. Built with Astro 5 and Catppuccin, featuring an interactive D3.js knowledge graph, Pagefind full-text search, Mermaid diagrams, and a Wavesurfer.js audio player for post summaries.

`$ neofetch --section power-user`

Daily Environment

OS: Fedora 43 + COSMIC Desktop
Editor: Neovim (LazyVim) — fast navigation is non-negotiable
Terminal: Alacritty + tmux + Starship
Shell: Bash + ble.sh + fzf — Fish-like UX, zero regrets
Theme: Catppuccin Frappé, everywhere

Quirks & Commitments

⌨️ Colemak-eD-EsAlt user — custom XKB with Spanish alternates. Painful to learn. Worth it.
🧠 Obsidian power user — atomic notes, Dataview dashboards, QuickAdd menus, a vault I'm probably too proud of
🔤 VictorMono Nerd Font with ligatures — because monospace should still be beautiful

`$ cat currently_learning.md`

Cyber Kill Chain & APT analysis
Applied Cryptography (PKI, zero-knowledge proofs)
Rust for systems & security tooling
OT/SCADA security nuances for critical infrastructure
