When I'm not immersed in my DevSecOps role, I enjoy a variety of activities. Here’s a glimpse into what keeps me good:

• 🎸 Playing instruments: I’ve been playing bass and guitar for 10 years, and I’m always looking for new ways to improve. Music is my go-to for disconnecting and self-expression.
• 🎧 Music: My tastes range from rock and alternative to hip-hop. Always excited to talk about favorite artists, let me know yours!
• 🎮 Video games: My brother introduced me to gaming on the PS2, and since then, I’ve been interested on action-packed games with deep stories.
• 🚗 Cars: I have a passion for driving and anything related to motorsports. I love staying updated and attending car meets, they’re a great way to connect with others who share the same enthusiasm.
• 🏋️‍♂️ Gym: Working in tech means a lot of sitting, so I make it a point to stay active and hit the gym (quite) regularly.
• 🌲 Hiking: There's nothing like spending time outdoors to reconnect with nature, something we often overlook in our busy lives.
