Security-Focused Software Engineer Frontend & Blockchain Developer DevSecOps & Application Security Specialist

Fullstack Engineer Frontend-Focused SEO Specialist Security Expert

I'm a Software Engineer specializing in Frontend Engineering, Blockchain Development, and Application Security (DevSecOps). My focus includes ๐Ÿ” Application Security, DevSecOps, Secure Code, OWASP practices, and CI/CD defense. I help teams build secure, scalable, and production-ready applications by combining strong UI engineering with secure-by-design principles across the entire software development lifecycle. I'm passionate about preventing data leaks, reducing attack surfaces, and writing clean, secure, maintainable code โ€” from backend APIs to CI/CD pipelines.

I have hands-on experience building decentralized applications (dApps) including meme coins, DAOs, NFT platforms, and blockchain dashboards using React, Svelte, Next.js, TypeScript, and blockchain platforms such as Hedera, Internet Computer (ICP), and Lisk.

Beyond building features, I focus on embedding security early โ€” from secure code reviews and OWASP best practices to CI/CD pipeline hardening, dependency scanning, and log protection. I bridge the gap between engineering, security, and product, ensuring systems are not only functional and beautiful, but also resilient and safe.

I bring a product-oriented mindset, with experience in MVP design, UX flow optimization, and feature prioritization, helping reduce onboarding friction and align technical execution with business goals.

Mission: To bridge software engineering and cybersecurity โ€” helping teams ship fast without compromising safety.

I bring hands-on experience in SEO, digital growth, and media production โ€” including videography, audio engineering, and social media โ€” so I can support product storytelling, developer advocacy, and brand presence alongside secure code.
