About

Hello, I’m Md Sultan Nasir Uddin — also known online as “Manik.” I’m a freelance WordPress and WooCommerce developer based in Dhaka, Bangladesh, with more than 18 years of experience building plugins, themes, and custom solutions for clients around the world.

I started my journey in web development in the early days of WordPress and have been part of the ecosystem ever since. Over the years, I’ve contributed to dozens of plugins, helped grow several WordPress products, and worked with clients ranging from small business owners to large agencies. WordPress is more than my profession — it’s a craft I genuinely enjoy.

What I Do

I work independently as a freelance WordPress developer. My day-to-day work involves designing and building custom plugins, extending WooCommerce stores, developing block-based themes, and helping clients ship reliable, well-tested WordPress products. I provide my freelance services to clients, including ByteEver, PluginEver, WP Ever Accounting, and a number of independent clients across different industries.

  • WordPress Plugin Development — custom plugins, public WordPress.org plugins, and premium extensions
  • WooCommerce Development — extensions, payment integrations, custom checkout flows, subscriptions
  • Block Editor (Gutenberg) — custom blocks, block themes, theme.json, full-site editing
  • REST API & Integrations — custom endpoints, third-party API integrations, headless WordPress
  • Performance & Code Quality — performance audits, code reviews, refactoring, technical consulting
  • Long-term Maintenance — ongoing support, version compatibility, security patches

A Bit More About Me

I’m self-taught in many ways — I learned by reading WordPress core, contributing to open source, and shipping real projects. I care deeply about clean code, sensible architecture, and writing software that’s easy for the next developer to maintain. I prefer simple, predictable solutions over clever ones, and I believe good documentation is part of good engineering.

Outside of writing code, I enjoy reading about technology and product design, exploring new tools, and spending time with my family. I live in Dhaka, Bangladesh, and most of my work happens remotely with clients across multiple time zones.

  • Languages: PHP, JavaScript, TypeScript, HTML, CSS/SCSS, SQL
  • Frameworks & Libraries: WordPress, WooCommerce, React, Gutenberg, REST API
