Clients usually come to me when they need someone to solve a technical problem, fix an existing application, integrate a new service, migrate a server, or build a reliable backend from scratch.
I focus on clean code, clear communication, and practical solutions rather than overcomplicating things.
If you have a Laravel, PHP, WordPress, WooCommerce, API, database, payment, server migration, CI/CD, or bug-fixing project, send me the details. I will take a look and let you know the best way to approach it.

Hi, my name is Aman and I have 12 years of experience as a Senior WordPress Engineer and Fullstack Developer. I have experience building robust and scalable web applications.
My areas of specialization include:
= WordPress Engineering =
I develop custom plugins and themes from the ground up. I have 10 plugins that I created that are free to download on the WordPress repository and I have built complex add-ons for WooCommerce, LearnDash, Gravity Forms, Ninja Forms, Formidable Forms, and Easy Digital Downloads. I write clear, standard-compliant code — no shortcuts.
= AI Integration & Automation =
I develop AI-powered applications for WordPress and Node.js as well as use OpenAI, Anthropic, and other LLM APIs. This includes smart form processors, content automation services, and custom AI chatbots that are integrated into other platforms. I can build the architecture for adding AI to your product.
= Fullstack Development (React + Node.js) =
I use React for the front end and Node.js or PHP for the back end. I focus on creating REST APIs, AJAX-heavy interfaces, and headless WordPress integrations as well as SPAs.
= API & Third-Party Integrations =
Substantial experience merging WordPress and bespoke applications with outside platforms:
• Payment Gateways: Stripe, PayPal (Standard, Express, Pro), Authorize.net, eWay, Dwolla
• CRMs: Salesforce, HubSpot, Infusionsoft, BaseCRM, ConvertKit
• Email & Marketing: Mailchimp, ActiveCampaign, GetResponse, AWeber, Constant Contact, Sendy, iContact
What differentiates me from others:
- I design systems that go beyond just 'working' today, but will also be sustainable and easy to maintain in the future
- Your codebase will be treated as my own: no unnecessary work, no rough hacks, and zero technical debt
- I build systems that enable clear and easy communication, so everyone involved will be aware of the project's status
- I focus my efforts on sophisticated and complex problems that others would find difficult
I provide production-level work on schedule, whether you require a bespoke AI feature within WordPress, a sophisticated API integration, a plugin that has been optimised for performance, or a fullstack React + Node.js application.
Let's create something great.
