Rubén Martínez Agramunt



🔹 Backend Engineer 🔹 Security-Minded 🔹 Built From Scratch

> whoami

Started in a bedroom — Linux installs, broken configs, shell scripts nobody asked for. That obsession with how things actually work never left. It evolved into something disciplined.

focus = [
    "backend architecture",        # not just REST endpoints
    "secure system design",        # threat models, not afterthoughts
    "infrastructure fundamentals", # what runs beneath the code
    "understanding systems under the hood",
]

# No cargo-culting. No copy-paste engineering. No magic I can't explain.
