CambodiaWhat I'm looking for
I break things before attackers do, testing web applications, APIs, infrastructure, and increasingly LLMs and agents across payments, banking, gaming, government, and e-commerce.
At Loma Technology, I lead and execute penetration testing across SIT, UAT, and Production environments, aligned with global enterprise security best practices.
Previously at VEILRON, I delivered offensive security, penetration testing, red team exercises, secure host reviews, and security improvement initiatives for clients across banking, gaming, e-commerce, and government. I also led presales conversations, solution briefings, demos, PoCs, and RFP/RFQ support across Asia.
At Deloitte, I assessed banking and national payment systems, reviewed Bakong Wallet, Bakong Core, Bakong Paygate, and mobile banking applications, and strengthened infrastructure security. I also lecture and have trained pentest students who placed among Cambodia's leading CTF competitors.
