About me

πŸ’» I kicked off my career in the Fintech world with Signzy, exploring the intricacies of digital security with prominent banks like HDFC, Axis, Citi, SBI, Pinelabs honing my skills in fortifying their digital infrastructures.
πŸš€ My expertise led me to Blockfi, a major player in the crypto industry, where I encountered extensive infrastructures and high-security measures. As a triager for the HackerOne bug bounty program, I thoroughly analyzed vulnerabilities, consistently reinforcing robust security.
πŸ›‘οΈ Currently, I'm leveraging my expertise at Klar, a prominent Mexican bank, where I'm actively involved in ensuring PCI compliance and spearheading application security programs. Additionally, I handle automation, penetration testing, vulnerability management, and product security as primary components of my work.
As your dedicated Security Engineer, I'm committed to strengthening digital infrastructures, ensuring optimal security, and making the cyber world a safer place, one vulnerability at a time. Let's connect and discuss how I can assist you in fortifying your digital defenses! πŸ‘‹πŸΌπŸ”
