Here’s what I expect to receive: • A clickable Figma prototype covering the complete purchase flow—browsing products, viewing details, adding items to cart, checking out, and tracking orders. • Core support screens such as sign-up / sign-in, profile, and basic settings to round out the experience. • A reusable component library (buttons, cards, nav bars, tab bar, etc.) and clear layout styles so our dev team can transition smoothly to high-fidelity design.

...completed AI-powered maintenance management SaaS platform that needs a specialist to take it from near-complete to fully production ready. The codebase is clean, well-structured, and built on React + TypeScript + Supabase. A detailed technical handoff document exists that outlines every remaining gap, every relevant file, and the estimated effort — so you would not be walking into the unknown. The work is not about building anything new. It is about closing specific, well-defined gaps: deploying migrations, hardening security configuration, setting up CI/CD, wiring server-side jobs, and connecting the AI layer to live data. Everything is already scoped and documented. A couple of quick questions before we go further: Are you currently available to take on a new projec...

...HR engine. First, the Applicant Tracking System needs deeper configuration: I want new custom fields and forms that match the way we evaluate candidates, smart workflow rules that move applicants automatically from stage to stage, and dashboards or reports that let me slice data by source, pipeline velocity, and hiring manager activity. Next, the Employee Onboarding module should feel personal yet hands-free. Create role-based checklists that populate the moment a hire is confirmed, trigger branded email sequences to the new joiner and stakeholders, and build any extra digital forms we need so paperwork is captured inside Zoho rather than over email. Integration points with the rest of Zoho People must stay intact. Performance Management also require...

My second book—a fresh collection of adult-oriented short stories—will be hitting the shelves in a few months, and I want it to enter the world with real momentum. I’m looking for a UK-based marketer who already understands the local reading scene and can turn curiosity into sales using the channels that matter most to my audience. The core of the launch will revolve around social media and carefully chosen influencer partnerships. Facebook and Instagram are the priority platforms, so I’ll need everything from eye-catching copy and visuals to smart ad placement and community engagement that actually sparks conversation.

I produce Case Files After Crime, a narrative true-crime podcast told in three acts. I need an editor who can transform raw voice tracks into a dark, suspense-filled cinematic experience rather than a simple “cut and clean” talk show. The finished mix must carry the weight of a thriller: long silences that tighten tension, carefully placed stingers, and smooth crescendos that drive each plot point forward. To hit that mark the episode has to lean on three elements: • Sound effects that feel authentic and unsettling • Background music that blends ambient textures with hip-hop-style cinematic beats • Narrative voice enhancement that keeps every word intimate and intense You’ll have my narration, interviews, and script notes. I’m c...

Hello, I am looking for a highly skilled, results-driven digital marketing expert who delivers real ROI — not just setup. I have a strong background in this field myself, so I fully understand how things should be done.

Your focus is simply: • Shake, stir, and serve in friendly but professional manner • Chat with guests, top off drinks, and keep the bar area tidy • Wrap up with a quick wipe-dow...

I need an experienced developer to dive into the current project, isolate the bugs, and deliver a clean, reliable version of the program that restores full functionality. You will have remote access to the controller and the full source package as soon as we agree on an NDA.

...that will be built with Python on the back-end and simple HTML/CSS on the front-end. The app’s primary job is to receive, store, and display user-submitted text, and it must do so behind a secure sign-up / log-in system. You’re free to choose Flask, Django, or another well-supported Python framework—what matters most is clean, well-documented code and a straightforward setup process. No complex front-end stacks are necessary; plain HTML (with a touch of CSS if you like) is fine as long as it keeps the interface clear and responsive. Deliverables • Fully functional web app running locally via virtualenv or Docker • User authentication flow (registration, login, logout, password reset) using best practices for password...

I’m streamlining some file-management tasks on my Linux server and need a concise, reliable way to tackle two things at once: 1) Recursively change file and directory permissions exactly as specified (think find + chmod/chown, but I’m open to any Bash, zsh, or POSIX-sh solution). 2) In the same workflow, locate and sort files by both their names and the text they contain so I can quickly review or pipe the results elsewhere. Please package the solution as a one-liner or small script with clear inline comments plus a short README that explains what each flag or pipeline does. I’ll consider the job complete when I can drop the command into a Debian-based shell, see the permissions update correctly, and get a neatly ordered list of matching files bas...

...specifically for large-screen Android tablets that will run in a Linux-based build and deployment environment. The end product has to feel seamless beside our existing web application, so rock-solid integration is everything. Here’s the core of what you’ll be doing: the app is brand new (nothing to refactor) and must ship with secure user authentication, real-time data synchronisation to our backend, and reliable push notifications. The server side is already live; you’ll consume our REST/JSON endpoints and make the tablet experience fully in step with the web version. Because this is a contract role I need someone who already has at least five years of hands-on APK work under Linux—comfortable with Android Studio, the Android...

I’m migrating our current SchoolERP Android application to Flutter and would like to begin with three key areas: 1. Home Screen – The new Flutter view must surface announcements and notifications at the top, show a concise dashboard overview of today’s stats, and provide quick-access buttons to the most-used modules. Smooth pull-to-refresh, badge counts, and Firebase push integration should mimic the existing behaviour exactly. 2. Profile – Students and staff need a tabbed layout that presents personal details, attendance records, and grades/performance, all pulled from our current REST endpoints. Data caching, photo upload, and simple edit forms already exist in Java and must be replicated in Dart without losing validation rules. ...
