Senior WP/JS Team / Agency for P2P Yacht Charter Platform (JetEngine CCT + Reactive JS Frontend)

Job Title: Senior WP/JS Team / Agency for P2P Yacht Charter Platform (JetEngine CCT + Reactive JS Frontend) Location Target: We are specifically looking for developers and boutique agencies from Ukraine, Eastern Europe, and the CIS region (excluding contractors currently located in Russia/Belarus). Job Description: We are looking for a cohesive team (or a boutique agency) to take over and complete a turnkey GoLive phase for CharterBnB.com (a P2P yacht charter classifieds and listing platform). Why We Need a Team (Not a Solo Dev): The attached SOW is highly multidisciplinary. It requires deep backend logic (custom SQL, JetEngine CCT), reactive frontend development (JS), UI/UX design polish, and content/localization setup. A solo developer will likely find this inefficient or overwhelming. We need an established team that can distribute these tasks among specialized experts (Backend, Frontend, Content/QA) to deliver quickly and cost-effectively. Project Status & Handover: To be completely clear: the platform as a whole is 95% built. We are hiring you to complete the final specific "GoLive" sprint detailed in the attached SOW, which is currently ~50% complete. We are transitioning to a new technical team because our previous developer recently accepted a full-time corporate role. The parting was amicable, the code is clean, and you are NOT stepping into a messy legacy nightmare. Note: Shortlisted candidates will be granted read access to our GitHub repository to evaluate the current codebase and open tickets before making any final commitments. What We Offer (Why Seniors love this project): • Clean Infrastructure: No cheap shared hosting or messy FTPs. You inherit a production-ready DevOps pipeline (Ubuntu, CloudPanel, Nginx, Redis, GitHub CI/CD, WPMerge). • Clear Scope: You won't be guessing what to do. You get a 20+ page detailed SOW and ~100 pre-written, structured tickets in GitHub. • Architectural Freedom (The "Black Box"): We care about metrics (TTFB, LCP, CLS), not micromanagement. As long as you meet the performance KPI and follow the Master Standard, how you write the code is up to you. • Financial Safety: 100% of the milestone budget is funded into Upwork Escrow on Day 1. Timeline & Commitment (Strict): • Duration: ~1 Month sprint to GoLive (the exact timeline is open to discussion and will be finalized after your initial Staging audit). • Availability: Full-Time dedication required. • Focus: Absolutely no parallel projects or side hustles during this period. We need your complete, undistracted immersion to meet the high-performance standards. ⚠️ IMPORTANT LANGUAGE & FILTERING NOTICE: The detailed 20+ page Statement of Work (SOW) is attached to this job post as a PDF in the Russian language. You MUST be fluent in Russian/Ukrainian to understand the business logic, UI copy updates, and backend documentation. Do not apply if you cannot process native-level Cyrillic technical documentation. Tech Stack & Architecture: • WordPress, ACF, WPML • Crocoblock Ecosystem (JetEngine, JetSmartFilters, JetFormBuilder) • Custom JS / JSON Endpoints Critical Architecture Constraints (The "Black Box" Rule): To guarantee extreme performance (TTFB below 300ms, LCP below 1.5s, CLS below 0.1), we do NOT allow standard heavy HTML server-rendering for maps and filtering: 1. Reactive JS Island: The search grid and map must operate via a custom JS script on the frontend. 2. Strict JSON Backend: The backend (JetEngine CCT Query) must output lightweight JSON data exclusively. 3. Zero Extra AJAX: Map marker popups must render instantly (below 200ms) from pre-loaded JSON without additional database queries. 4. No Hardcoded HTML: The UI design must remain fully editable via Elementor. Your JS must clone DOM templates, not hardcode HTML strings. Budget & Estimate Note: The budget listed on Upwork is just a placeholder. We expect YOU to provide a realistic fixed-price estimate and timeline after auditing the attached 20+ page SOW. We value cost-efficiency, but quality and meeting the TTFB below 300ms metric are our top priorities. If you are a serious team that values modern architecture and fixed-price reliability, we are ready to start.
