I'm an Electronics Engineer, Front-End Web Developer and Technical SEO Specialist with 5+ years of experience. My main focus is front-end development with React — together with JavaScript, HTML and CSS — building fast, accessible and search-optimized websites. I founded Webraf to combine development, technical SEO, analytics and AI-assisted workflows into practical digital solutions for businesses.
Across agency and freelance work I have supported more than 100 client projects: technical and on-page SEO audits, Core Web Vitals and performance improvements, front-end fixes, and CMS work with WordPress, along with regular site maintenance and security when a project needs it.
Today I bring development, data and AI together to build solutions that are measurable, verifiable and made to last. If something can be tracked, optimized and improved, that's the work I enjoy most.
