Professional profile

Precision-driven.
Security-minded.

I am a Full-Stack Developer and Cybersecurity Specialist with a background spanning software engineering and high-stakes operational technology. Before transitioning into software, I spent over a decade managing precision IoT systems and large-scale operations — work that demanded engineering discipline and consequence-awareness most developers only encounter through hard experience.

I founded and built an online pharmacy platform from scratch — architecting every layer from frontend to payment systems to security hardening and CI/CD pipelines. That project validated a security-first engineering approach in production: zero security incidents, 99%+ uptime, handling regulated pharmaceutical data at scale.

I hold all the academic and professional qualifications required for this role, and continue developing expertise in applied cybersecurity through directed study aligned with OWASP standards and current threat research.
