### Project Description: B2B corporate established platform built on Custom Core PHP 8.3. (Important Note: The upgraded PHP 8.3 logic and modern features like WhatsApp integration exist ONLY within our current Arabic files). Needed an expert Backend/Frontend developer to take this updated Arabic codebase as the ONLY root engine and refactor it into a strict Single Codebase (Zero Code Duplication). This unified codebase must dynamically serve two distinct domains ([login to view URL] for Arabic/RTL and [login to view URL] for English/LTR). ### Key Architectural Requirements: 1. Dynamic Routing & Core Unification: Implement a centralized routing mechanism to detect the incoming domain and dynamically switch languages, database configurations, and UI directions using a SINGLE set of core files. 2. Dynamic Database Mapping: The platform utilizes parallel tables for different languages (e.g., 'business_profile' for Arabic and 'business_profile_arabyos' for English). You must implement a centralized SQL rewrite layer/mapping logic in the configuration so that all existing database queries automatically route to the correct table based on the active domain without duplicating the query paths across files. 3. Internationalization (I18n): Cleanly extract all hardcoded UI strings from the core Arabic files into dedicated language files ('lang/[login to view URL]'). You will extract the English translation strings from our legacy English files and place them into 'lang/[login to view URL]'. 4. Modern CSS Mirroring (Strict): You must refactor the stylesheet using "CSS Logical Properties" (e.g., margin-inline, padding-inline, start/end) so one single stylesheet dynamically handles both LTR and RTL layouts. Creating separate RTL overlay files or manual "page flipping" is strictly prohibited. 5. Preservation of Core Logic: Existing functional logic, background scripts, and automation cron-jobs in the root directory must remain fully operational. --- ### Security, Testing & Delivery Terms 1. Isolated Staging Environment: All deployment and testing will happen inside an isolated staging directory on our Hostinger server. Restricted FTP access will be provided. No live/primary database access will be shared; you must provide the SQL alteration scripts for us to execute on our end. 2. Code Duplication Audit: The final delivery will undergo a strict source code audit. If any duplicated files or separate LTL/RTL stylesheets are found, the delivery will be rejected. 3. Deadline: Maximum of 5 consecutive calendar days for full implementation. ### Sequential Milestone & Payment Terms (Final Release Upon Full Completion) IMPORTANT: No milestone will be released individually during the project, the project budget is divided into 3 sequential milestones. : * Milestone 1 (40% of Budget) - Funded immediately upon project award: This is the ONLY milestone funded (escrowed) at the start. It will NOT be released until the entire project is completed. This phase covers: establishing the upgraded Arabic PHP 8.3 files as the single codebase on our subdomain ([login to view URL]), connecting the two-domain routing config, integrating [login to view URL] / [login to view URL] into the agreed frontend pages, completing the necessary CSS/JS/LTR-RTL adjustments to a clean standard. * Milestone 2 (30% of Budget) - Funded ONLY after Phase 1 is verified on the server: This milestone remains UNFUNDED (no escrow) at the start. It will be funded in the dashboard only after Phase 1 is deployed and visually verified. Once funded, it will NOT be released. This phase covers: Full English text extraction from legacy files and complete Arabic text organization for the agreed frontend pages. * Milestone 3 (30% of Budget) - Same as previous milestone 2, (no escrow) until Phase 2 is completed. Once funded, it covers: Final thorough review, bug fixes, and stable operational testing on the subdomain. FINAL RELEASE CONDITION: **The total project budget (100% across all 3 milestones) will be released to the freelancer ONLY after our management performs a full source-code audit on our Hostinger server, confirms Zero Code Duplication, verifies dynamic database mapping, and officially signs off on the flawless functionality of both domains. tested, and approved on our staging server. . **Time Deadline: within maximum 6 consecutive calendar days. If you are a senior developer who stands behind the quality of your code and accepts these transparent structural terms, please apply with your exact timeframe.

Hi, Your architecture goal is very clear: one PHP 8.3 core, two domains, zero duplication, and no fragile RTL/LTR split. That’s exactly the kind of refactor where clean routing, table mapping, and CSS logic matter more than quick edits. I’ve worked on custom PHP/MySQL systems, language-file extraction, and server-side routing refactors, so I can unify the Arabic codebase as the single engine, wire domain-based language/database switching, and keep cron jobs and background scripts intact. 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. If you’d like, I can start by auditing the current Arabic files, identifying the routing entry point, and mapping the table-rewrite layer before touching the frontend pages. Which file currently acts as the main bootstrap/router for domain detection and database initialization? Best regards, Asad

Merging egyptmart and arab-mart into a strict single codebase under PHP 8.3 requires a robust abstraction layer to handle domain-driven routing and parallel table mapping without inducing query latency. To eliminate code duplication, I will implement a bootstrap middleware that intercepts the host header, binds the active language and database prefix dynamically into the PDO connection layer, and leverages CSS logical properties for seamless LTR and RTL switching in a unified stylesheet. Cron-jobs and background scripts will be isolated from HTTP context to preserve automation integrity. Having architected high-concurrency multi-tenant platforms over the last 15 years, I am fully aligned with your Hostinger staging workflow, strict code audit requirements, and the 5-day delivery window. Let us review the codebase structure and initiate Milestone 1 immediately. Gaurav Panwar Senior Full-Stack & System Architect (15+ Yrs Exp)
