Professional Summary
Technical SEO Specialist with 8+ years as a Senior Full-Stack Engineer and 2+ years of hands-on SEO and
performance marketing experience. My core advantage is rare in the SEO market: I don't just audit websites
— I write the code that fixes them. I build natively SEO-optimized platforms from scratch using HTML, CSS,
JavaScript, React, and Next.js (SSR/ISR), then execute the on-page and technical strategies to scale them.
My strongest areas are technical SEO (rendering strategy, Core Web Vitals, crawl budget, structured data)
and on-page optimization at scale (semantic HTML, internal linking architecture, automated metadata
generation). I have working knowledge of off-page tactics (guest posting, parasite SEO, brand citations) and
continue to develop in that area. I leverage standard SEO tools (Ahrefs, Screaming Frog, Semrush, GSC)
alongside automation (Python, N8N, Make.com) and AI tooling (Claude Code) to drive measurable organic
growth.
