JetEngine Expert / Frontend Developer (UI/UX & Trust)
Hello. We apologize for the use of Russian in the project description. The entire technical stack, Master Checklist, and communication with the current development team were conducted in that language. To maintain the accuracy of terminology and the effectiveness of the tech lead's work, the description is published in the original language of the documentation. Thank you for your understanding.
Project Description:
We are looking for a Senior Frontend Developer (JetEngine Expert) for the final polishing of interfaces and setting up user interaction logic for the P2P yacht rental platform — CharterBnB.com
The project is at the MVP+ stage, and the architecture is ready. Your task is to transform the complex backend functionality into a user-friendly, "marine," and trustworthy interface.
Area of Responsibility:
- Core Synchronization: Implementation of interfaces that work in conjunction with a custom SQL engine (Hybrid CCT Engine).
- UI/UX Refactoring: Setting up filters, forms, and maps for instant response (AJAX).
- AdBlock Compatibility: "Cleaning" the code from elements blocked by extensions.
- Marine Storytelling: Integrating brand style and marine terminology into control elements.
Technical Stack:
WordPress, Elementor, JetEngine (Query Builder / CCT), JetSmartFilters, JetFormBuilder, GitHub Actions, WPMerge.io.
Your Key Engineering Challenges:
- CCT & Map Sync: Technical linkage of the search interface (JetSmartFilters) with a high-performance availability index (CCT). Ensuring simultaneous AJAX updates of the map and list without page reload.
- AdBlock Warfare: Total refactoring of CSS class names and IDs. We need to eliminate occurrences of ads, promo, banner, so that the personal accounts of owners do not disappear due to ad blockers.
- Zolushka Protocol (UI): Design of the Early Bird promotion: implementation of crossed-out prices, accent stamps, and dynamic banners for Private and Business rates.
- Smart Conversion Hooks: Implementation of the Phone Privacy mechanism (hidden number with Reveal logic via Ajax) and visual character counters in forms.
- Auth Redesign: Redesign of the login system based on tabs (Lessor/Lessee) with clear visual separation of user roles.
Team Interaction:
- Technical Subordination: You work under the direct supervision of Tech Lead (Block 1). All changes are submitted via Pull Request in GitHub.
- Database Synchronization: Setting up the interface (JetEngine/ACF) in the sandbox and transferring through WPMerge.io only after approval from the tech lead.
- Gatekeeper Protocol: You are the sole owner of the frontend-dev branch. Direct access to the Live server is not available.
Conditions:
- Payment: Fixed for the entire scope "turnkey".
- Format: through the Freelancehunt Safe.
Our Rules of the Game (Master Standard SSoT):
- GitHub First: No edits via FTP. Only Atomic Commits, PR, and Branch Protection.
- Step 0: Any work in the sandbox starts with "Pull from Live" via WPMerge.io.
- No-Code Priority: Custom JS/CSS only where JetEngine capabilities are insufficient for KPI.
- Responsibility: We value autonomy. You choose architectural solutions, but you are responsible for the outcome.
Details:
A complete technical specification, detailed Master Checklist, and access will be provided after a short technical interview. We need a specialist who values order and discipline.
We look forward to having you on board!
“Important: The full scope of tasks, technical metrics (KPI), and development rules are documented in the Detailed Technical Specification and Master Standard SSoT, which are provided to the candidate before the opening of the Safe. The reservation of funds in the Safe is made under the condition of fulfilling all requirements of these documents. Acceptance of work is based on 100% compliance of the final result with these standards.”

Good day! My colleague and I have been professionally engaged in technical automation and the development of high-load interfaces on JetEngine for over 4 years, so we will help your team transform the MVP CharterBnB into a premium product with native interaction logic. We will implement backend hooks for Phone Privacy (Reveal logic) and custom counters in JetFormBuilder, paying special attention to the visual separation of roles Lessor/Lessee. Our 4 years of experience is confirmed by projects drkukharevich.rivne.ua, crave-agency.com.ua, jk-solution.com.ua, where we have already worked under strict Git-flow protocols. We will ensure technical excellence in executing the Zolushka Protocol for promotional rates, set up instant feedback for filters without reloading the map, and submit all changes through Pull Requests according to your development hierarchy. We work reliably, value order in documentation, and are ready for a technical interview to confirm competencies in Query Builder and CCT.

Hello! I have carefully studied your Master Standard SSoT and the technical requirements for the CharterBnB.com project. I specialize in complex solutions in the WordPress / JetEngine stack and value order and discipline in code just as you do.
My alignment with your challenges:
Expertise in JetEngine: I have extensive experience with CCT and Query Builder. I understand how to synchronize complex filters with the map and ensure instant AJAX response of the interface.
Clean code and AdBlock protection: I know how to build interfaces that are resistant to ad blockers through proper naming of selectors and DOM structure.
Git & Workflow: I work according to the GitHub First standard. Atomic Commits, Pull Requests, and teamwork through a tech lead are normal for me.
No-code Priority: I always try to maximize the capabilities of JetEngine/Elementor, and only where architecturally necessary do I add custom JS/CSS.
I am ready for a brief technical interview and to complete the Master Checklist. I value autonomy and am ready to take responsibility for the final KPI of the project.
…
I look forward to the opportunity to come on board! (The maximum budget for this project is 27,000, but until I see a real technical specification, I cannot say for what amount I will complete it.)
I wanted to clarify one technical point regarding WPMerge.io: do you provide access to your account for database synchronization between Live and Sandbox, or does the developer have to provide the rest of the infrastructure independently?

- product UI/UX tuning (pricing scenarios, promotions, badges, dynamic banners, storytelling in visuals);
- complex forms: role separation (Lessor/Lessee), character limits, reveal logic (Phone Privacy via AJAX).
…
We are used to working with a clear Master Checklist, through PR, with branch protection and a tech lead as the sole gatekeeper. We are ready to undergo a short technical interview, familiarize ourselves with the Master Standard SSoT, and take responsibility for the frontend "turnkey" to 100% compliance with your standards.

Good night!
My name is Dmytro, from King Kong Lab. I have reviewed the description — the project looks technically interesting and well-structured, with a clear logic of operation through Git, sandbox, and clear processes.
We have experience working with WordPress + Elementor + JetEngine (CCT, Query Builder, JetSmartFilters, JetFormBuilder), as well as implementing complex logic on the frontend with AJAX without reloads. We have worked with custom data structures, synchronization of lists and maps, as well as optimizing the UI for quick response.
We can address your tasks:
- implementation and optimization of filters and forms with instant updates (AJAX)
- synchronization of JetSmartFilters with CCT and display on the map
- refactoring the frontend for AdBlock (cleaning classes, IDs, logic)
- redesigning UI/UX (auth, user roles, conversion elements)
- implementing logic such as Phone Privacy, counters, dynamic UI
… - adapting the interface to the product style
We understand the importance of working through GitHub (PR, atomic commits), working in staging, and synchronization through WPMerge. We also adhere to a no-code first approach and connect custom code only where it is truly necessary.
We are ready to undergo a technical interview, familiarize ourselves with the Master Checklist, and connect to the project.
