Full-stack engineer with a WordPress specialization.

I build backend systems, not pages.

12+ years working on large-scale PHP and WordPress applications. My focus is clean architecture, performance, and security. The work that keeps production systems running reliably at scale.

At aThemes (now part of Awesome Motive), I led backend development for a WooCommerce plugin running on 10,000+ active stores. Before that, I built custom WordPress platforms, headless integrations, and REST API systems at RGBCode.

I work best on projects where the backend complexity is real: custom plugin ecosystems, WooCommerce platforms, and systems that need to hold up under production traffic.

Problem

Site builders and developers needed lightweight, purpose-built Elementor addons and Gutenberg blocks that existing solutions either overcomplicated or did not cover.

Solution

Built and published multiple plugins on WordPress.org from scratch. The flagship plugin adds a fully responsive Elementor carousel widget with support for images, testimonials, and team members. A separate Gutenberg block plugin handles pros and cons lists with responsive layouts. Each plugin went through the official WordPress.org review process and is actively maintained.

“Nahidul is a talented, hard-working and reliable developer. He worked with us at aThemes on our Merchant plugin for WooCommerce, handling everything from front-end tasks to complex backend logic.
