I’m building a single mobile solution that lets my farm crew handle every HR and day-to-day workflow in one place, and I want it available on both iOS and Android from day one. Core features I need you to weave together: • Interactive farm map built for quick navigation of paddocks, sheds, water points and other assets. • Deep Xero integration that pushes and pulls Payroll, Invoicing and Expense tracking data in real time, so our books stay tidy without double entry. • Spreadsheet-style “grid math” sheets baked into the app—think lightweight Excel that lets staff run fertiliser rates, feed mixes or cost calculations on the fly. • Digital timesheets with tap-to-clock-in/out and GPS stamping to verify location. • Live task lists, pro...

I am setting up a steady pipeline of hiring rounds and need a seasoned backend specialist to act as my external interviewer. The role is purely technical-assessment focused and covers both Node.js and Python since our stack toggles between the two. Here’s the flow I have in mind: • Before each session you craft or select a concise, real-world coding exercise that touches on algorithms, data processing logic or lightweight API work—nothing contrived, just the kind of task an engineering hire would tackle on day one. • You run a live 45- to 60-minute remote interview with the candidate, giving them the prompt, watching their screen, asking clarifying questions and probing for edge-case thinking. • Immediately afterward you deliver a written scorecard: code cor...

I have a set of file-transfer web applications that were built with Claude and are already running in production, yet several core features are malfunctioning and the overall interface feels dated. Functionality fixes needed: • Users are unable to sign up or log in reliably, so authentication must be re-engineered and hardened. • Data-submission forms either fail validation or never reach the backend; they need to post correctly and surface friendly error messages. • Key pages should present stored files and status updates, but the information is missing or out of sync. • System-generated emails (account confirmation, transfer notifications, etc.) do not arrive, so SMTP or any transactional-mail service hookup has to be inspected and corrected. UI/UX impro...

I have a public Shopify app that moves orders from merchants’ stores into my dropshipping panel. Everything works in live stores, but the moment I try to push the app to the Shopify App Store, the review team flags a handful of items—mostly around webhooks, the OAuth flow I’m using, and the standard compliance checklist. What I need now is a fresh, expert set of eyes to: • Audit the current implementation (webhooks, OAuth, data handling, UI, and any other compliance touch-points). • Patch whatever is preventing a clean submission. • Walk me through a final resubmission—staying on board until the app is approved. I’m happy to open the codebase and Partner Dashboard on a quick Google Meet so you can see everything firsthand. When you rep...

I need a developer who can take my concept for a dedicated property-listings platform and turn it into a clean, responsive website that buyers and renters will actually enjoy using. The core of the job is building an intuitive listings engine—nothing agency-branded or management-oriented, just a straightforward place where users can search, browse, and dive into individual properties. To make the site genuinely useful I want three essentials fully working on day one: • Advanced search filters that let visitors refine by price, bedrooms, neighbourhood, and any other tag we add later. • Interactive maps that plot each listing in real time so users can explore areas visually. Google Maps or an equivalent JS map library is fine as long as it’s smooth on mobile. &bu...

I’m creating Shakke shakks, a focused social networking site where members of niche or hobby‐based communities can connect without the clutter of mainstream platforms. The very first release must centre on a smooth, real-time messaging experience—one-to-one and small group chat—because conversation is the heartbeat of these interest circles.

I need an experienced next js and backend developer to iron out a handful of issues inside my résumé builder solutoon The most urgent blocker is registration: the OTP never reaches the user, so the Firebase phone-auth flow stops before verification even begins. Once that is reliable I can move on to polishing the core résumé screen. Users must be able to open an existing résumé and freely edit its current sections; no adding or deleting is required, just clean in-place edits. While you are in that view, please standardise typography—style, size and colour—so every heading, sub-heading and body line looks consistent across devices. Page-break logic also needs attention; long résumés should split predictably rather than ...
