Product Engineer

Building secure products for real-world enterprise environments.

Jason Sariwating • Enterprise Security • Product Engineering • Data Protection

I'm a Product Engineer at PT. i-Trust Data Teknologi, a digital security company focused on protecting identities, systems, and infrastructure. I build internal tools, customer-facing applications, and security solutions that turn complex technical requirements into practical, maintainable products.

My work focuses on HSM, PKI, key management, encryption, tokenization, automation, and full-stack application development. Through enterprise security projects, I have also developed working familiarity with Indonesia's Personal Data Protection Law, ISO/IEC 27001, PCI DSS, and related international compliance frameworks. I use this context to better understand solution requirements and customer discussions, without presenting myself as a compliance auditor or subject-matter expert.
