Focuses on
Fast, accessible websites that rank and convert.
Building the web, one commit at a time.
I'm Abinesh — a full stack engineer and senior WordPress developer with 3+ years delivering production-grade websites for global clients. Shipping since 2022, focused on WordPress, React, headless CMS, and technical SEO.
Day-to-day: architecting projects with ACF and Gutenberg, wiring React into CMS environments, and digging into the technical SEO problems others avoid.
“Fast websites shouldn't be a premium feature — they should be the baseline.”
