Software Engineer. Security focused, AI enabled. GIAC GFACT Certified
Building secure, cloud-native web applications with React, Next.js, AWS, and AI-powered features.
About
Background and approach
I'm a software engineer with a strong focus on frontend development, cloud technologies, and cybersecurity. I recently earned the GIAC Foundational Cybersecurity Technologies (GFACT) certification through the SANS Institute, validating my knowledge across networking, operating systems, cloud platforms, web technologies, and core security principles.
I bring together real-world software engineering experience and formal security training to design and build applications that are secure by design, scalable, and production-ready.
In addition to traditional web development, I work with AI-enabled features, including LLM integrations and automation workflows, always with a security-aware mindset around data handling, access control, and responsible AI usage.
I'm continuously expanding my skills at the intersection of software engineering, cloud security, and applied AI.
