I’m rolling out a full-fledged hotel booking ecosystem that lives on three fronts: a customer-facing Android app, an iOS app, and a browser-based admin portal. The apps must let travellers search live inventory, choose an exact room (e.g., “Room 457” instead of a generic “Double”), pay securely, and leave ratings and reviews once their stay is over. Property data can never be stale, so real-time room availability has to stay in sync with external channels such as Airbnb and ; whichever API or iCal approach you prefer is fine as long as double-booking risk is zero. Each hotel owner will have an individual account with the freedom to update rates, photos, descriptions, blackout dates, and promotions at any moment without touching code. Multi-layer user per...

I need a bespoke payment gateway built and fully verified for the Ghanaian and Nigerian markets. It must natively process mobile money, direct bank transfers, and debit / credit card payments without routing funds through foreign intermediaries. During user onboarding I want a KYC-driven verification flow—government-issued ID capture, selfie match and real-time checks against local watchlists—so the service launches already compliant with regional regulations. You will handle the entire build: API design, merchant dashboard, customer checkout screens, sandbox and live environments, plus submission to every required bank, network or regulator until the gateway is officially approved for production use. Once live, I expect: • Production-ready REST / Webhook APIs with samp...

I need a full-featured car-rental broker site that pulls live rates and availability from Renteon, Carnect, CarTrawler and a few additional suppliers through their XML, extranet or REST APIs. Once the feeds are in place, visitors must be able to: • search and instantly compare offers across all connected partners, • complete a reservation on our own booking engine, and • leave a post-rental rating and review that appears on the vehicle page. A straightforward email-and-password sign-up / sign-in flow is all that’s required; no social logins for now. The checkout has to handle credit or debit cards, PayPal and direct bank transfer, routing payments to the appropriate supplier account or to us, depending on the integration rules each API stipulates. Please build ...

I need my current WordPress site, which runs WooCommerce for its online menu, to talk directly to the PetPooja API. Two key things must happen automatically: 1. Every time I update an item or change a price in PetPooja, the same change should appear in WooCommerce without manual work. 2. When a customer places an order on my website, that order has to reach PetPooja instantly so it shows up on the POS alongside in-store tickets. A lightweight custom plugin or a clean code snippet that hooks into WooCommerce is fine, as long as it keeps core files untouched and can survive future updates. Clear setup instructions and basic error-logging are part of the hand-off, and I’ll test the flow by changing a price in PetPooja and placing a live order on the site. If you’ve integrated...

My website needs a clean, modern feedback form dedicated to gathering Customer satisfaction data. The form should feature a 1-to-5 rating scale as the primary input, presented with an eye-catching yet unobtrusive UI that matches my existing design language. Key points • Single page or modal embed that drops neatly into my current HTML/CSS stack. • Visual polish matters: responsive layout, intuitive star or slider control for the 1-to-5 scale, clear typography, and accessible colour contrast. • Vanilla JavaScript or a lightweight framework is fine; avoid heavy libraries unless they genuinely improve UX. • On submit, data should post to an endpoint I specify (REST or simple email handler), with graceful success/error messaging. • Code must be well-commente...
