Every page, template, global element and dynamic content link has to look and behave exactly the same once the theme update is complete.

I will provide full FTP and wp-admin access along with the current child theme so you can trace all overrides.

    I’m midway through building an online platform for the UK property market and now need expert help to finish the multi-role dashboards and harden the system. The core objective is to let buyers, sellers, agents and other professionals follow an end-to-end transaction in one place. Each role must have its own dashboard that: • Shows every milestone relevant to that user, updating in real time so all parties can see progress. • Hosts secure document management for contracts, searches and proofs. • Provides rich communication tools: email and WhatsApp notifications plus the in-app messaging option I’ve selected for on-platform chat. Beyond the build, I need you to stress-test every scenario typical to a UK sale—offers, surveys, chain breaks, completio...

    I’m looking to develop a comprehensive CRM software tailored to my business needs, with advanced AI capabilities integrated directly into the system. The goal is to create a smart, efficient, and scalable platform that not only manages customer data but also automates workflows, improves lead management, and enhances decision-making through AI insights. The CRM should include features such as lead tracking, customer interaction history, sales pipeline management, automated follow-ups, and reporting dashboards. Additionally, I want AI to assist with tasks like predictive analytics, lead scoring, customer behavior analysis, and automated communication (such as smart replies or reminders). The system should be user-friendly, secure, and accessible across devices (web and mobile). Custom...

    I have two parallel needs that can start immediately. First, I’m digitising a batch of documents. Your task here is straightforward data entry: lift the information from the files I provide and place it into the matching fields of an online form. Accuracy is critical, so I’ll review submissions as they come in, and I expect everything returned by the agreed deadline. If you are reliable and comfortable with basic computer work, this part will be easy for you. The larger portion of the project is the creation of a voice-driven AI assistant that runs natively on a Windows laptop. It must: • Wake on a hot-key or spoken trigger and understand natural-language voice commands. • Search the web, answer general questions, and perform quick look-ups locally. • Auto...

    I need a purpose-built Chrome extension that outperforms the existing Amazon Relay “grabbers.” The core of the project is a bot that will automatically book loads the moment they appear while actively monitoring and tweaking the booking parameters in real time so I do not miss high-value opportunities. Performance is my top priority. Extensions currently on the market lag, freeze, or crash when Amazon’s traffic spikes; yours must keep response times razor-sharp and handle errors gracefully without manual refreshes. A clean interface is welcome, but raw speed, stability, and clear status feedback matter most. Key deliverables • A production-ready Chrome extension (source + compiled) that logs into Amazon Relay, continuously scans for new loads, auto-books based on...

    The base is sketched out and the processes I want are clear, but nothing is wired up yet. I now need the full automation layer built in Airtable—and, where it makes sense, orchestrated through Make (formerly Integromat). What I expect the finished system to handle • Data entry and updates: records created through forms or external APIs should populate the right tables, trigger look-ups, and keep linked records in sync. • Notifications and alerts: whenever key fields change or deadlines approach, automatic email nudges need to go out to the relevant team members. • Report generation: scheduled roll-ups and summary views must be compiled into PDF or CSV and sent automatically. Integrations The base will pull or push data via a few third-party APIs (details read...
