I need a developer who can design and implement an API connection from scratch, then integrate it smoothly into my existing system. I am flexible on the architecture—RESTful, GraphQL, or even SOAP—so please suggest the approach you feel best suits modern maintainability and performance. Because the system’s purpose is still being refined, the API should be built in a way that can serve multiple potential use-cases, such as: • syncing data with external partners, • feeding internal applications, • or acting as a gateway for future third-party services. Key expectations • End-to-end setup: specification, development, basic documentation, and a tested deployment. • Secure authentication and solid error handling. • Clear code comments...

I run a software development and AI-automation agency that specialises in streamlining hospital operations, from intelligent appointment scheduling to predictive analytics for resource planning. I’m ready to scale our reach inside the healthcare sector and I’m looking for a sales professional who feels at home on the phone, opening doors with hospital administrators, IT directors, and decision-makers. Your main focus will be cold calling: researching the right contacts, crafting an opening that speaks to their pain points, and turning first conversations into live demos or discovery meetings that I’ll step into and close. If you have supplementary tactics up your sleeve—email sequences, LinkedIn follow-ups, conference networking—I’m happy to hear them, ...
I need a developer who already knows their way around the Android Enterprise API to wire it into our existing Android application so that we can take full control of company-owned devices. The end goal is straightforward: once your work is in place, IT should be able to enroll a new handset in seconds and push or update policies on demand—no manual tweaking, no sideloaded scripts. The focus is squarely on two areas: • Device enrollment – the app must trigger zero-touch or QR-based enrollment flows, register the device with our backend, and confirm that the management profile is active. • Policy enforcement – from lock-screen rules to app-install restrictions, every policy needs to sync reliably with Google’s management framework and report status back ...
I’m putting together a single card that keeps every student secure, connected and accounted for. With one tap the card must open doors, pay for meals, log attendance automatically and, when a student feels unsafe, trigger an SOS call while broadcasting real-time GPS coordinates. The moment SOS or any geofence breach occurs, the right staff member has to see an alert immediately. Three user groups will interact with the platform. Students need a simple companion app or portal to view balances and safety status. Teachers must be able to take attendance and receive emergency notifications for their classes. Administrators require a full dashboard: live location map, transaction logs and system configuration controls. You’re free to choose the hardware interface—RFID, NFC, ...

Financial and progress reporting • Budget forecasting that updates whenever a quantity or rate changes • Expense tracking down to line-item level, flowing straight from site entries into consolidated cost reports • Actual-vs-budget views that flag overruns immediately &b...
We are looking to develop a cloud-based multi-vendor rental marketplace platform for renting electronics, gaming consoles, laptops, and other assets. The platform will include vendor management, product listings, real-time booking, secure payments, logistics tracking, and an admin dashboard. It should be built with a scalable cloud architecture and support future expansion. Due to the sensitive nature of the project, a refundable security deposit of 10% (approx. $2,300) may be required from the selected developer/team to ensure data security, commitment, and protection against potential breaches. The amount will be fully refunded upon successful project completion. Key modules I expect you to deliver 1. Responsive web application plus companion iOS and Android apps sharing a common API...
I’m putting together a small proof-of-concept web app and need an experienced React developer who can move quickly from wireframe to working build. The interface should feel simple and minimalistic, built entirely with reusable React components and clean JSX. State and prop management must enable real-time updates so the screen always reflects the latest data without a page refresh. Navigation will rely on a menu with dropdown items; no side drawers or tab bars are required. Behind the scenes, I want a lightweight Node + Express API hooked to a MongoDB collection. The front end should consume that API for full CRUD while keeping response times snappy. Deliverables • React front end with minimalistic styling and dropdown menu navigation • Real-time data layer (WebSock...
I need the existing ANZ gateway upgraded to ANZ Bank Worldline Global gateway so customers can continue to pay without leaving the site. You’ll work directly with the Worldline REST API and build and install the new gateway. I will supply API keys, test credentials and server access to the AWS server where the website is hosted. Acceptance will be based on: 1. Passing transactions in Worldline’s sandbox, then live environment, with clear success and fail states reflected in the OpenCart order timeline. 2. No PHP notices, warnings or overrides to core files; code follows PSR-12 and OpenCart coding standards. If you’ve previously integrated Worldline let me know—the learning curve will be minimal. I’m aiming to test and push to production in a week, so ...
I have an up-to-date digital model of our facility, yet I’ve never taken the next step into true BIM-based asset management or a live Digital Twin. My goal is to turn that existing model into a practical maintenance tool that lets me track every piece of equipment, monitor energy performance in real time, and make data-driven decisions without getting lost in technical jargon. Here’s what I need from you: • Assess the current model to confirm it is twin-ready and map every asset with the right metadata. • Connect, or at least prototype the connection to, energy-usage data (BMS, IoT meters, or similar) so the twin reflects live consumption. • Build intuitive dashboards or reports for asset tracking, fault history, and energy trends—preferably in a pla...
I need to add real–time Australian driver’s-license verification to my existing VOIP platform immediately. Callers will enter or speak their licence details during the call flow; the system must then query the official Australian DVS (or a comparable API you recommend) and return an instant pass/fail result before the call proceeds. The only document we will accept is a Driver's License, so the solution should extract and validate all standard licence fields—name, address, date of birth, licence number and expiry—while logging a full audit trail for compliance. I am flexible on the underlying VOIP stack, provided the final workflow runs smoothly on my current hosted instance and is maintainable in-house after hand-over. Deliverables • Fully integra...

I need a small-to-mid-size piece of software that will fully automate an internal process. The exact workflow and data sources will be shared once we sign an NDA, but in broad strokes the task involves reading structured input, applying a set of business rules, and producing an export that can be fed straight into our existing system.

I need a very small Universal Windows Platform (UWP) application whose sole purpose is to launch a local batch file, which in turn starts my existing Java-based desktop application. Once the finished UWP package has been provided, I will configure it as the single locked-down app in Windows 11 Assigned Access, so please also supply the Application User Model ID (AUMID). The launcher should display no user interface at all — no buttons, splash screen, status messages or other visible elements. Its only function is to execute a batch file stored locally on the device, using a path I will provide, and then hand off control to the Java application. No additional security controls, keyboard restrictions or logging are required; reliability, simplicity and a clean hand-off are the priorit...

I have a one-minute questionnaire ready to go and I need a surge of genuine answers from corporate IT professionals—developers, sysadmins, architects, project managers, security engineers, anyone who works in an IT function inside a company. The link to the form is set; what’s missing is reach. Any channel is fine with me. If you can tap LinkedIn groups, niche Facebook or Twitter communities, targeted email lists, Slack workspaces, or industry forums, great—just keep every submission 100 % organic. No bots, paid ads or click-farms; I want real people sharing real opinions about the concept behind my startup. Deliverables • An outreach plan that lists the channels you’ll use and why they hit the IT corporate crowd • Fast execution and live trackin...
I need a single widget in my Unreal Engine 4.23 project tweaked so it looks and behaves correctly in both 16:9 landscape and 9:16 portrait. The current layout works in landscape, but when the device rotates the background stretches badly and some buttons drift out of place. Here’s exactly what I’m after: • Keep the existing vertically-scrolling background (it moves upward). No parallax, blur, or other effects—just the simple loop already coded. • Re-arrange or mask that background so it fills the screen cleanly in both orientations, still scrolling upward in portrait and landscape. I’ll be re-using the assets already in the project; nothing new needs to be designed. • Double-check every interactive button on that screen after the background work...

I need a fresh set of eyes on my JavaScript API documentation. The technical accuracy is already solid, yet the introductory material feels dense and newcomers struggle to grasp the bigger picture. Your task is to re-write these opening sections so they flow naturally, remove any unnecessary jargon, and guide readers smoothly toward the deeper method references that follow. The end product should read in a balanced, professional voice—clear enough for intermediate developers, yet polished enough to reflect an enterprise standard. Think MDN clarity with just a touch of conversational warmth. Key focus • Introduction & Overview: restructure headings, tighten paragraphs, add brief context where transitions feel abrupt. • Consistency: align tone, capitalization, and...
My Flutter app is in the testing stage and I’m ready to push it all the way to both Google Play and the Apple App Store.

End-to-end store release • Configure signing, build flavours and store listings. • Submit the initial production build to Play Store and App Store with all required screenshots, icons and metadata. 2. Automated build & test pipeline • Set up Fastlane as the backbone of the CI/CD flow so that every tagged commit produces an incremental build. • Integrate unit, widget and Patrol end-to-end tests; run them automatically in Firebase Test Lab (or a comparable cloud lab) a...
My production web application is built with Python 3 and Django, and a few stubborn bugs have crept in. I already have a Git repository and a staging server waiting for your fixes; you will branch, patch, and open merge requests there so we can review together. What I need from you is straightforward: reproduce each reported issue, identify the root cause, deliver clean, well-commented code that follows Django best practices, and prove the fix with automated tests. Once the branch is merged I’ll handle deployment, but a brief note outlining any required migrations or environment tweaks will keep the rollout smooth. You will have SSH access to the staging environment and detailed bug reports in the issue tracker the moment we start. Familiarity with Django ORM, templates, and the us...
*UPFATE AT BOTTOM OF AD * I’m working from a fully formed 3D conceptual model that exists in my head and can be illustrated and described clearly in terms of design and intended functionality. I’m looking for help translating that model into original, authored code. The work will be task-based and compartmentalized. Each contribution should be clean, readable, and logically transparent — no copy-paste solutions and no black-box abstractions. I need to be able to fully understand and verify the logic behind what’s written. *UPDATE* Before engaging anyone in detail, I wanted to confirm that the platform can support the type of work required for my project. Because of the nature of the system, I can’t disclose internal mechanisms or architecture at this stage....
My Vibe codebase is already running smoothly in a near-complete state; the core modules work and the architecture is in place, but it still needs the last round of features and polish before I can confidently push it to production. Your job is to step in, review the existing repository, and add the final functionality that will turn this almost-ready build into a release candidate. What I need from you • A quick orientation with the current code so you understand its flow and dependencies. • Implementation of the remaining features I will outline in our kick-off call—think small but critical touches that complete user journeys and admin controls. • Unit and integration tests for anything you add or refactor so coverage stays healthy. • Clean, readable com...
I need an experienced Beckhoff TwinCAT engineer who can take full ownership of PLC programming, HMI development, and overall system integration for a medium-scale manufacturing line now entering its pre-production phase.
