Summary
🤩
Rockstar🎓
Top SchoolHelena Mariano is a software engineer based in Sydney with seven years of professional experience building secure, performance-focused systems for payments, identity, and eCommerce. She has deep expertise in embedded and cryptographic systems from a decade of work on MULTOS smart card operating systems and HSM integrations, and now applies that systems-level rigor to AI-powered search and product discovery at Sajari. Her background spans low-level C/C++ firmware and high-level web and cloud stacks (C#, .NET, SQL, JavaScript), enabling her to bridge hardware security, payments compliance, and modern SaaS engineering. She has led cross-border team moves and knowledge-transfer projects, hiring and onboarding new engineering teams while preserving high-volume production services. Not obvious from the title: she pairs an Honours degree in Mechatronics with a Physics BSc, reflecting a strong foundation in both hardware and analytical problem solving. That combination makes her particularly effective at turning demanding security and performance requirements into reliable, production-ready products.
