Kastle Media is hiring a freelance WordPress developer to build a new client website using our existing Kastle Core custom WordPress theme and our approved schema plugin. This is a custom-code WordPress build. It is not a page-builder project. The successful freelancer will work within the existing Kastle Core architecture and build a new, client-specific website from scratch. Each client has its own design, content, brand identity, page layouts, and CSS. Do not copy page templates, CSS, HTML, components, or visual styling from another Kastle client website unless a specific technical pattern has been approved for reuse. AI-assisted development is acceptable. The final output must be clean, maintainable, accessible, responsive, secure, documented, and production-ready. Build in WordPress using the existing Kastle Core custom theme. Do not install or use Elementor, Divi, WPBakery, Beaver Builder, Bricks, Oxygen, or any other visual page builder. Build pages with semantic HTML, CSS, and JavaScript only where it is genuinely required. Do not replace, modify, or bypass the Kastle Core theme architecture without written approval.

Working inside an existing WordPress architecture without page builders is the part that matters here, because the real risk in jobs like this is breaking theme conventions or creating code that becomes hard to maintain later. I’d approach this by first mapping the Kastle Core structure, identifying approved reusable technical patterns, and then building the client-specific layouts cleanly with semantic HTML/CSS/JS only where needed. I’ve handled custom WordPress builds where the requirement was to stay inside an existing theme system rather than replacing it with a builder or shortcuts. That kind of work needs discipline around CSS structure, accessibility, responsiveness, and clean handoff documentation, not just getting pages to “look right.” - How many unique page templates or layouts are expected for this client site? - Will the design files and final content be fully provided before development starts? - Is there an existing coding standard or documentation format you want followed for the handoff?

Hello, I can build Kastle Media’s client website directly within the existing Kastle Core custom WordPress theme, preserving its architecture while creating a genuinely client-specific implementation. I’ll translate the approved designs, brand identity, content, and page layouts into clean, semantic HTML, responsive CSS, and focused JavaScript only where interaction requires it. The build will avoid all visual page builders and will not reuse another client’s templates, CSS, HTML, components, or styling without explicit approval. I’ll also integrate the approved schema plugin, ensuring the result is accessible, secure, maintainable, documented, and production-ready across devices. My approach includes careful review of the Kastle Core conventions first, component and template development aligned with the existing structure, responsive implementation, accessibility checks, browser testing, and final code cleanup before launch. Which Kastle Core templates, reusable technical patterns, and schema-plugin conventions should I review before beginning the client-specific build? I’m ready to work carefully within your established system while delivering a distinct, polished website for this client. Best regards, Muhammad Awais

Hi, thanks for sharing the project details — this looks like a great fit for my skills. I work with custom WordPress theme development using semantic HTML, CSS, and clean PHP, so building within the Kastle Core architecture without page builders is exactly my kind of project. Here is how I will approach it: Custom build within Kastle Core, no page builders used. Client-specific CSS, layouts, and components built from scratch. Clean, accessible, responsive, and production-ready code throughout. A few questions to help me get started on the right foot: 1. Does the client already have finalized designs or mockups, or will design direction come from Kastle Media? 2. Are there specific page types or interactive features that need particular attention in this build? 3. What is the expected timeline, and will I have access to an existing Kastle Core staging environment to work within? Looking forward to contributing to a well-structured, quality build for your client. Azeem Amin

Hi — Elias here from Miami. I see that you’re looking to develop a new WordPress website for Kastle Media. The goal is to create a platform that not only reflects your brand but also serves your clients effectively. What usually matters most here is ensuring the site is both user-friendly and secure. A common issue in projects like this is managing plugins and customizations without compromising performance or security. The tricky part is usually ensuring the site can scale with your business while maintaining a smooth user experience. My approach would be to structure the site with a focus on maintainability and future updates. I’d recommend a clean architecture that allows for easy plugin management and updates, ensuring long-term reliability. I've worked on similar WordPress projects, where I implemented robust security measures and optimized the user interface for better engagement. A few questions to better understand the scope: Q1 – What specific features are you looking to include for client interactions on the site? Q2 – Are there particular plugins or tools you plan to integrate? Q3 – What are your expectations regarding site performance and scalability as your client base grows? Happy to go through the details and suggest the best technical approach. Looking forward to hearing from you.

Hi, When you say each client gets their own design and CSS—do you have a design file ready, or will I be building the visual layer from scratch based on your brand guidelines? That'll help me nail the scope. I've built custom WordPress sites without page builders before, and I know how to work within an existing theme architecture without breaking things. The budget and timeline shown are just placeholders—once we clarify scope, I'll send you actual numbers. Regards, Nurul Hasan

Hi there, I can see the hidden risk here: this isn’t just a WordPress build, it’s about fitting cleanly into Kastle Core without breaking the architecture. That’s exactly the kind of custom-theme work I handle well. I’ve worked on WordPress builds, theme-level customizations, semantic HTML/CSS implementation, and schema/plugin integrations, so I can build each client site from scratch inside your existing framework while keeping it maintainable, responsive, secure, and accessible. I’ll be careful not to reuse visual components unless they’re explicitly approved, and I’ll keep the code aligned with the theme structure. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. Could you share the preferred content structure, any approved reusable patterns from Kastle Core, and whether there are specific accessibility or SEO rules I should follow? Looking forward to your reply so we can finalize the exact plan. Best regards, Asad
