    My OpenCart store is currently unable to complete orders whenever customers choose at checkout. The payment window opens and the customer submits their card details, but the process never reaches the final “order confirmed” stage in OpenCart, so no order is recorded in the back-office and no confirmation email is sent. Other gateways behave normally, so the problem appears isolated to the integration. I need someone who knows OpenCart’s checkout workflow inside out and is comfortable digging into the extension, transaction logs, and any JavaScript or server-side conflicts that might be interrupting the callback. Your goal is simple: identify the failure point, apply the fix, and prove that an order can move cleanly from payment to confirmation every time. Deliverable...

    I need a clean, modern website where I can publish my dealership’s vehicles, attaching multiple photos and a video to every listing without fuss. The entire experience must feel seamless on a phone—image galleries should swipe smoothly, video playback must be instant, and buttons and forms have to fit comfortably on any small screen. Key points I care about: • A straightforward back-office that lets me add, edit or remove vehicles and drag-and-drop both photos and videos (common image formats + MP4 or YouTube/Vimeo links). • Lightning-fast, mobile-optimised front-end with clear calls to action for potential buyers. • Clean code and a framework or CMS that makes future updates easy for someone non-technical. • Final hand-off on my server, plus a quick ...

    Serwis jest zrobiony w ok. 80%. Głównymi jego elementami są: system komentarzy, google maps, rejestracja użytkowników, logowanie, panel administracyjny do zarządzania użytkownikami i treścią na stronie. Technologia: wordpress, php, js,, mysql, google maps api. Ja zajmuję się grafiką i designem. Szacuję, że dokończenie serwisu powinno zająć ok 2-4 miesiące. Współpracę widziałbym tak, że podsyłam paczkę z opisem kilku elementów do zrobienia na stronie, wyceniamy koszt i osoba, z którą się porozumiałem, realizuje te kilka elementów. Takich paczek powinno być kilka. Celem 'dokończenia serwisu' jest to, aby można go było wypuścić teraz w podstawowej formie na internet. Jeśli uda się to zrobić, i jeśli serwis będzie działał bez zarzutu prze...

    I need a reliable system that can take our prepared text and video assets and publish them automatically across multiple social networks. After our kickoff call I will share the exact platform list and credentials, but the solution should be flexible enough to add or remove channels without major re-work. Key objectives: • Configure multi-platform auto-upload through Comet, mapping captions, thumbnails, tags, and any platform-specific metadata. • Create scheduling rules so each post goes live at the time I set—daily, weekly, or according to custom calendars. • Build a distribution workflow that queues content, validates it against each API’s limits, and triggers retries on transient errors. • Add an error-detection layer with clear logging and alerts ...

    I need a web-based automation that can reliably scan VFS Global’s calendar, pick the earliest available slot that matches preset criteria, complete the booking flow end-to-end, and confirm the reservation—no manual clicks from our side. Core scope • Appointment scheduling is the heart of the build. The script or service must log in with rotating credentials, pass the usual captcha / queue hurdles, search by mission and visa type, then lock the chosen slot before it disappears. • A notification system is also essential. As soon as an appointment is secured (or fails), the system should push an email and, if possible, a Telegram or SMS alert to our team. Access & roles Only Admins—our internal staff—will use the interface. A straightforward d...

    I need a single developer who can take my company’s custom web-app idea from blank screen to production-ready release. The frontend must be responsive and polished; React or Vue are both fine, provided the choice supports fast performance and clean component structure.

    I need an embeddable chat box that sits on my website and allows a private, two-person conversation between me (manager) and a customer. No sign-up, password, or account creation should get in the way—when a customer clicks the chat icon or a direct link I email them, the window simply opens and we can start talking. Core objectives • Web-only integration (the platform choice I selected) • One manager seat, one customer seat per session • Real-time text exchange with automatic refresh or websockets so neither side has to reload the page • Clean code I can drop into any page plus a brief setup note (where to paste the script, how to start a new session) Optional niceties—if you already have them in your toolkit, feel free to include typing indicator...
