👋 Hey, I'm Fernando

Software Engineer · Backend · Secure Systems · Educator


🖤 What I Do

I’m a software engineer with a strong backend focus and a security-first mindset.
My work lives at the intersection of clean code, reliable systems, and real-world constraints.

I enjoy:

  • Designing backend services that are predictable and observable
  • Building APIs that are easy to maintain and hard to misuse
  • Turning operational data into actionable insight
  • Teaching others how to think like engineers, not just write code

Think: backend engineer + system thinking + defensive security awareness.


🧠 Core Strengths

Backend & Software Engineering

  • Backend development with Python, C# and Java
  • FastAPI · Flask · .NET ecosystems
  • API design, service boundaries, and data modeling
  • Writing code that is testable, observable, and maintainable
  • Git-based workflows and CI/CD with GitHub Actions
  • Containerized development with Docker on Linux

Security-Aware Engineering

  • Secure-by-default API and backend design
  • Threat modeling and defensive architecture
  • SIEM pipelines (Elastic, Wazuh, Filebeat) as engineering systems
  • Understanding attacker behavior to improve system resilience
  • Practical mindset: build → observe → break → improve

Teaching & Technical Leadership

  • Teaching Python from fundamentals to backend APIs
  • Mentoring junior developers into professional engineering habits
  • Explaining complex system behavior in clear, practical terms
  • Strong communication between technical and non-technical audiences

🛠 Daily Tooling

Tools evolve.
Engineering fundamentals don’t.


📌 Current Focus

  • Building resilient and observable backend services
  • Improving monitoring, logging, and alerting pipelines
  • Designing secure and maintainable API patterns
  • Automating operational and engineering workflows
  • Teaching real-world engineering thinking through practice

🧩 A Quote I Keep Close

“Sometimes you must reveal the threat to motivate the solution.”
Barnaby Jack

A reminder that good engineering is proven in reality, not slides.
