    We have an in-progress Expo/React Native mobile app that's built on top of an existing web app (B2B SaaS platform).

    I need a brand-new travel-affiliate website focused on flight bookings, Hotel Bookings and car rentals using AI agent. From the first line of code to the final deployment, the build must be clean, fast, and mobile-responsive. Live fare data should flow in through an affiliate API such as Skyscanner, Travelpayouts, or any comparable source that you feel comfortable integrating. Visitors have to be able to search, filter, compare, and then click straight through to the provider with my tracking parameters automatically attached. A streamlined admin area is essential so I can update affiliate keys, tweak markup, add meta tags, and read basic analytics without touching the codebase. Good SEO foundations (schema, crawlable URLs, fast load times) are expected from day one. Timeline is tight: e...

    My custom-built HTML/PHP site already collects leads, but none of that data is flowing back into Google Ads yet. I need the full loop closed - 15 days: • Implement Google Tag Manager tags and triggers so a successful form submission completion fires a conversion. • Link the tags to the corresponding Google Ads conversion action and confirm through the real-time and debug tools that every submission is counted—no duplicates, no misses. • Build the initial Google Ads campaigns (search and, if suitable, display) around the same goal, then keep an eye on the account during the engagement to make sure each recorded lead lines up with what GTM reports. A job well done means I can refresh the Ads interface and immediately see verified form-submission conversions, along ...

    I’m looking for a skilled software developer who can take an e-commerce idea from concept to a production-ready web application. The core deliverable is a full-stack solution: a responsive storefront for shoppers, a secure checkout flow, and an intuitive admin area where I can manage products, orders, users, and basic analytics. While I’m open to the specific tech stack, I do expect clean, well-documented code, modern UI practices, and deployment guidance to a cloud host of your choice. Payment gateway integration, user authentication, and GDPR-compliant data handling are must-haves. The finished application should be easy for me to extend in the future, so clear architecture and concise documentation will be part of the acceptance criteria. If you’ve launched e-commerc...

    I need step-by-step guidance on designing, building, and deploying AI agents that automate day-to-day business tasks, with a clear focus on customer support. The tutoring should cover everything from selecting the right large-language-model framework to integrating the finished agent into real-world channels such as chat widgets, email, or help-desk software. Key topics I expect us to work through include: • Planning an agent’s role, conversation flow, and required data sources • Building, fine-tuning, or prompt-engineering the model so it reliably answers customer queries • Connecting the agent to external tools (APIs, CRMs, ticket systems) for end-to-end automation • Setting up monitoring, analytics, and continual improvement loops • Development be...

    I need a Google Chrome extension, built for Windows, that will sit on my VDS and quietly turn each new eBay sale into a completed Amazon order without any manual input. How the flow should work 1. I forward every eBay “Order Confirmed” email to a dedicated mailbox. 2. The extension checks that mailbox, pulls the buyer’s name, shipping address, item SKU, and quantity. 3. With Amazon already logged-in on the VDS, it adds the correct item to cart, completes checkout, and logs the order ID back to a simple local report (CSV or similar). 4. If any detail is missing or the item is out of stock, the process pauses and flags the order for my review instead of guessing. Key requirements • Must run headless on the VDS yet be installable as a regular Chrome extensio...
