about

I am a Full-Stack Developer focused on transforming complex ideas into high-performing, secure, and intuitive web applications. Currently operating as a Contractor, I bridge the gap between modern frontend speed (Next.js & TypeScript) and the versatility of Headless CMS architectures.

With a Master’s degree in Cybersecurity and hands-on experience developing core features for global SaaS platforms like WebinarJam and Kartra, I approach every project with a "Security by Design" mindset. I don’t just write code; I build automated, resilient systems that drive efficiency and deliver real business value.

What I do!

Frontend Development

I create responsive, ultra-fast user interfaces using Next.js, React, and TypeScript. I prioritize performance (Core Web Vitals) and clean design to ensure an exceptional and seamless user experience.

Backend & Headless Architecture

I develop scalable server-side logic and robust APIs using PHP (Laravel) and Node.js. I specialize in Headless WordPress/WooCommerce integrations, connecting modern frontends to powerful backends via REST or GraphQL.


Database Management

I design and manage high-performance relational databases using PostgreSQL and MySQL. My expertise lies in architecting efficient data schemas and optimizing complex queries to guarantee data integrity and lightning-fast performance.
