How’d you get into fighting? What can you say about your professional record?

I’ve always enjoyed fights. I started in jiu-jitsu in 2013. I have six bouts on my record, with a single loss to Vinicius “Mamute” Moreira. I always look for a knockout, despite originally coming from ground fighting. I come from jiu-jitsu and every day I look to improve my striking. Whenever I see an opening, I look to finish by KO.
