    I need a secure, browser-based portal where my business customers can log in, view all open invoices, see the applicable cash discount for each one, and immediately settle the balance through our bank-transfer gateway. After the customer confirms payment, the system must generate a downloadable payment advice and then e-mail an official payment receipt automatically. Core workflow 1. Pull invoice data from our ERP (REST API available) and display it in a clean, filterable grid. 2. Let the customer tick the invoices they wish to pay; the portal calculates cash discounts in real time. 3. Route the net amount to our bank-transfer gateway (we already have the API docs). 4. On success, create the payment advice PDF, mark the invoices as paid through the ERP callback, trigger the e-mail...

    I want to automate my wedding invitations through the WhatsApp Business API. The flow I have in mind is simple, yet has to feel personal: • Each guest receives a WhatsApp message— not a PDF or static flyer— but an actual chat message that carries their name, the date, time and venue, plus a sleek, modern image that matches our overall design. • The message should ask whether they will attend. A quick-reply or any similarly friction-free option that records a Yes / No is ideal. • A unique QR code must be generated for every confirmed guest. That code will be their digital “ticket” at the entrance and needs to scan reliably on standard readers. From your side I expect: 1.

What I still need is the end-to-end build that ties those pieces together and, most importantly, addresses the real pain points users have voiced: they want clear guidance on how to prepare for interviews and a way to match their resume to each job.

    Bug fix in a real-time chat application. Context: chat messages are stored as generic ChatEvent rows in Postgres, with no dedicated flag distinguishing a private message from a public one — private messages currently arrive with a text-based marker prefixed to the message body (e.g. a bracketed tag at the start of the string). The frontend chat component already has a fully built, distinct rendering path for private messages (different visual treatment) — it just never gets used, because the API route that serves chat events to the frontend maps every single row to the generic "chat" type regardless of content, so the private-message type the frontend already knows how to render is never actually emitted.

    I’m maintaining the open-source iOS project hosted at and need an experienced Swift / Objective-C developer to focus exclusively on bug fixes. The code builds, but several runtime issues and edge-case crashes are holding back a stable release. Scope • Pull the repo, build it with the latest Xcode and iOS SDKs, and reproduce any crashes or malfunctions you encounter. • Trace the root cause in code, patch it cleanly, and document the change in concise commit messages. • Where a fix touches multiple modules, write unit or UI tests that prove it works across those sections. • Submit a pull request so I can review the diff and run the CI pipeline before merging. Deliverables 1. Fork/branch with all resolved bugs committed. 2. Test cases (XCTest) coveri...

    I need a web-based billing solution tailored for my sweet shop so that every invoice is generated automatically without manual effort. The system must live entirely online—no desktop installs—so I can log in from any browser, add new products or customers, and watch invoices issue themselves. The single most important capability is automated invoicing. Two flavours of automation are mandatory for my workflow: • Scheduled invoicing for standing orders (for example, the cafés that take a mixed-laddu box every Friday). • Instant invoicing triggered the moment a sale is recorded in the sales screen or through a simple API endpoint. Everything else should revolve around those rules. I’d like a clean dashboard where I can: • Review, edit, resen...

    I want to launch a fully-functional platform where people can browse, book, and interact with “rental boyfriends” online. The core build should cover partner and client registration, profile pages with photos and bios, a simple booking flow, secure payment handling, and real-time chat or messaging so sessions can be coordinated smoothly. The interface must look contemporary on desktop and mobile, load fast, and remain intuitive for first-time users. You are free to suggest the best tech stack, but I’m leaning toward a mainstream framework (React or Vue for the front end, Node/Express or Laravel for the back end) so future maintenance is straightforward. A clean API layer is important because I plan to add a mobile app later. Key deliverables: • Responsive web app (...

    I’m expanding our platform and want an experienced DevOps engineer (minimum five-year track record) who can take ownership of our existing toolchain and push it forward.

Fully functional web version, ready to deploy on a standard LAMP or Node.js stack. 2...
