I'm Abinesh Selvarasu — a Senior WordPress Developer and Full Stack Engineer based in Tamil Nadu, India. With 3+ years architecting production-grade web platforms, I specialize in custom CMS architecture, headless WordPress solutions, and performance engineering.

Day-to-day, I architect scalable CMS components using ACF Pro and custom Gutenberg blocks, integrate REST & GraphQL APIs, and solve complex Core Web Vitals and technical SEO challenges that keep platforms fast, secure, and search-engine optimized.

Through Gradiolex, I apply this same enterprise-grade discipline to every project — delivering modern Next.js applications, Flutter mobile apps, and custom CMS platforms built to last.

Our principles

Three rules.
Every build.

Principle is what separates progress from motion. Here's what we hold to, on every build.

01 / Craft

Engineering Craft

Every line of code, every component, every asset — built with attention to detail that compounds. Refactor over patch. Architecture over fix. Long-term maintainability over shortcuts.

02 / Measure

Measurable Speed

Performance proven by empirical metrics. Core Web Vitals (LCP, INP, CLS), page speed scores, and technical SEO hygiene are non-negotiable standards on every release.

03 / Complete

Guaranteed Completion

Progress without a finish line is just motion. We engineer for completion — ensuring every project is fully tested, optimized, and ready to scale.

Quality Benchmarks

Engineering specs.
Built to perform.

Every web platform built by Gradiolex is benchmarked against rigorous empirical engineering standards.

ACF Pro

Modular CMS Blocks

Custom Gutenberg blocks and ACF Pro field structures giving content managers total control without bloat.

Architecture · Headless & Custom

Technical SEO & Schema

JSON-LD structured data, dynamic OpenGraph generation, semantic HTML5 tags, and clean sitemap hierarchy.

Unused Script Bloat

Handcrafted CSS tokens, strict TypeScript types, zero heavy page-builder plugins, and optimized asset splitting.

Code Hygiene · Clean Craft
The stack

Tools we
trust.

Stack is a means to an end. We choose tools that ship fast, scale well, and stay maintainable over years.
