Welcome to the cave!

My name is Juanjo, and I’ve been working as a software engineer for seven years now (and growing!). During this time, I could play not only with different programming languages, libraries, and frameworks, but luckily I could also learn some DevOps and security skills too along the way.

I’ve been a free-time learner for a while now, and I love studying different technology stacks. I also studied for an MS degree in cybersecurity, and I’m constantly learning new stuff on Tryhackme (I got the junior pentester cert here too). To be honest, I’m having a great time.

In case you’re curious, this is my current tech stack:

Software engineeringDevOpsPentesting
Java (Dropwizard, Springboot, Maven…)DockerWeb frameworks: ZAP, Burp Suite, Nikto…
NodeJS (Typescript, React.js, Express, Fastify…)Kubernetes (Minikube, AWS and Azure implementations)Metasploit
Python (Fastapi, LLM and embeddings implementation…)IaC (terraform, AWS CDK…)SQL and noSQL injection
Cloud: AWS, Azure, GCP, digital oceanSQL, NoSQL (PostgreSQL, MySQL, Supabase, Firebase…)basic OSINT
Event-driven (AMQP, Kafka…) event-sourcing, DDD architectures.CI/CD (Github actions)Password/hash cracking: John the Ripper, Hashcat…
Ruby on Rails

My philosophy is built on top of three main pillars: adaptability, transparency, and technical excellence:

  1. Adaptability: I consider myself an open-minded engineer. I adapt to the needs of a project, even when learning a new tech stack is necessary.
  2. Transparency: Communication is key. Effective communication is the only way to build trust and confidence. It is also the only way of providing high-quality value to projects.
  3. Technical excellence: I’ve always been a curious and active learner, constantly trying to get over my skills. With this mindset, I try to give my best to solve problems and give value in the most effective way possible.

New technologies bring new opportunities to the industry, and allow us to be more efficient in our day-to-day work.

This site serves as a knowledge database for my posts, which go from trying software engineer and DevOps technologies to penetration testing machines at Tryhackme or Hackthebox.
