...contact-model equations ready for Altair EDEM; what’s missing is the C++ plug-in that turns those formulas into a working user-defined contact model inside the software. The work involves three core pieces. First, translate the equations I supply directly into EDEM’s API so the solver calls them instead of the default contact routine. Second, expose the key coefficients through a small, in-program GUI—graphical sliders alongside numeric input fields—to let me adjust values on the fly while a simulation is paused. Third, write lightweight data-logging code that captures selected force, overlap and energy terms each timestep and streams them to a CSV for later analysis. I will provide: • A document with the exact mathematical expressions, variab...

...networking experience to Android users. The core idea is a clean, modern mobile app where people can create profiles, follow others, share posts (text, images, short video), and chat one-to-one in real time.

Here is what I need from you: • Full Android codebase (Kotlin or Java) ready for Android Studio • Backend setup for user auth, real-time chat, feed storage, and push notifications (Firebase, Supabase, or a comparable stack) • Basic but attractive UI/UX that can be expanded later: light/dark themes, intuitive navigation, and accessible design • A signed APK plus clear instructions for a Play Store release • Document...

I run a metal-working shop equipped with a CNC milling machine and I’m looking for someone who can create an efficient, production-ready program directly in Mastercam. The job is straightforward: I supply the 3D model (STEP or native SolidWorks file) together with basic tooling info and any fixture details, and you return a fully proven Mastercam file plus the post-processed G-code for my Haas controller. Because we cut only metal, optimal feeds, speeds, and toolpaths that minimize cycle time and tool wear are essential. Please make sure the program includes: • The complete .MCAM file with clearly labeled operations and tool list • A setup sheet outlining tooling, offsets, and any special notes for the operator • Ready-to-run G-code tested in Ma...

I’m refreshing our program collateral and would like a brand-consistent, creative timetable that we can share both digitally and in print each week. You’ll be working with our recently updated logo and existing brand palette, so please be ready to match the exact colours I supply. What I need shown in the layout are every session title and its time slot; facilitator names are handled elsewhere, so keep the grid clean and focused on those two data points. The overall feel should be lively, engaging and easy to read—think bright illustrations or subtle accents rather than anything too corporate. I’ll provide: • the updated logo files (SVG and PNG) • our HEX/RGB colour references • a sample of last term’s timetable with the new week’...

All data must move securely between the web portal, the two mobile apps, and the database layer without duplication or loss. Technical expectations I am open to modern frameworks—React or Vue for the web front end, Swift/Objective-C and Kotlin/Java (or a cross-platform solution such as Flutter or React Native) for the mobile layer, and a scalable REST or GraphQL API behind it. Containerised deployment on AWS, Azure, or GCP with automated CI/CD, monitoring, and routine backups is essential so maintenance stays predictable.

...the next several months. The immediate need is to design and implement RESTful APIs that handle user authentication and authorization, data retrieval/manipulation, and a handful of third-party integrations. Most of our existing micro-services are written in Python and Java, with a few high-performance components in Go, so the more comfortable you are jumping between those languages the better. You’ll be expected to: • Draft an endpoint specification we can review together. • Build the services in clean, idiomatic Python, Java, or Go (your choice per module), following REST best practices. • Wire in secure auth (JWT, OAuth2, or similar) and role-based access control. • Integrate external services where required, shielding the core logic behi...

I have a digital recipe guide that needs to start earning right away, and I want it selling on three fronts—Etsy first, then Gumroad and Payhip. Your main mission is to wire in a rock-solid affiliate program on each platform that pays a 50 % commission on every confirmed sale. Getting that referral engine right is the priority, but the rest of the build-out has to be airtight too. Here’s the flow I’m aiming for: you open fresh shops (or optimise the current placeholders if faster), hook up PayPal and card payments, drop in the product files, and ensure the listings look native to each marketplace. Before upload, swap the price text inside the PDF to the new figure I’ll supply—no design overhaul, just that quick update. Once the shops are live, I need ...

The task is strictly programming and development—no copy-writing, layout, or graphic work is involved—so every hour can go straight into writing, refining, and explaining Python code. Here’s what I need from you: • Review the modules I already have, spot weak points, and suggest or implement improvements. • Add any missing functionality so the program meets its intended purpose. • Comment the final code clearly and walk me through the key decisions you make; I need to understand the logic well enough to answer follow-up questions at university. • Provide runnable, error-free files that behave exactly as we agree in our initial specs. I’ll deliver my current repository and a concise ...

I’m rolling out a new feature that touches both ends of our stack. On the backend we run Java 21 with Spring Boot micro-services, alongside a small Node.js/Python layer that exchanges events through Kafka. The frontend is split between an older Angular module and a newer React interface. The job is to design and code the complete feature, wiring it cleanly into every affected service and UI surface. You will: • Extend (or create) the relevant Spring Boot endpoints, making sure they publish and consume the right Kafka topics. • Update the Angular dashboard and the React SPA so the user experience is seamless across both frameworks. • Keep code idiomatic, unit-tested, and pushed to our Git repo via pull requests. Acceptance criteria • All API tests p...

I’m creating an online store for cosmetic products and want the codebase to feel as professional as anything you would ship to production. The backend must be written in Java with Spring Boot, exposed through well-structured REST endpoints, and persist data in MySQL. On the client side I only need a clean, responsive interface built with plain HTML, CSS and vanilla JavaScript—no heavy frameworks—so that the focus stays on clear architecture rather than flashy UI libraries. Core features I expect: • Role-based authentication for Admin and Customer accounts, supporting registration, login and logout with secure password storage. • Admin dashboards to add, edit and retire products, plus view basic order information. • Customer-facing catalogue with...

I’m expanding several engineering teams for top-tier MNCs and rapidly scaling tech start-ups and need skilled people who can jump in right away. The first seats I must fill are: • Software Developers who are fluent in React, Node, and/or Java. If you can architect front-end components in React, build robust APIs with Node, or craft enterprise-grade services in Java, you’re already on my shortlist. • Data Analysts & Data Engineers able to turn raw data into clean, actionable insights. Solid SQL skills are essential, and if you have experience with Python, Spark, or comparable tooling, that will be an added advantage. • UI/UX Designers who can translate complex product ideas into polished, user-centric interfaces, balancing aesthetics with ac...

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. 3. School Contacts & Calendar – For this first sprint I only need the staff directory portion live. Search, role filtering, click-to-call, and email links should work out of the box. The calendar view may stay read-only for now; it simply has to render the same event feed we already expose in JSON....

...Android-only mobile app from concept to Google Play release. The exact domain is still flexible—e-commerce, social networking, productivity, or another category that makes strategic sense—so I’m looking for a developer who can help me shape the idea as well as code it.

Think of it as one cohesive product where users can play, chat, share photos, connect with friends, and still reach for built-in tools that make daily life easier. Here is what I already know I need: in-app messaging, seamless photo sharing, and a robust friend-connection system. Because we’re targeting Android only, you’re free to lean into Kotlin or Java and make the most of Google-first services—Firebase for real-time chat and push, Play Games Services for leaderboards or achievements, and any modern Android Jetpack libraries that speed development while keeping the codebase clean. I’ll handle concept art and copy; you’ll take charge of architecture, clean UI/UX, feature implementation, and release-rea...
