Halo, saya
Athala Angwyn Renaldi
Software Engineer & Cybersecurity Specialist with a focus on secure development and proactive defense. As a Certified ISO/IEC 27001:2022 Lead Auditor, I combine robust backend engineering with deep analytical security to build and protect resilient digital infrastructures.
Tentang Saya
My journey in tech is driven by a simple philosophy: true security starts at the code level. While my foundation lies in building scalable backend architectures, my passion for cybersecurity has led me to actively stress-test and harden those very systems. I have successfully conducted VAPT on government networks, led security audits, and implemented secure SDLC practices in enterprise environments. I thrive in bridging the gap between developers and security teams, ensuring that every project I touch is not only highly functional but also prepared to withstand real-world threats.
