...scan, update, and confirm movements on the go. • Implement role-based access, automated alerts, and API hooks so the system can sync with existing ERPs and carrier systems. Tech preferences I’m flexible on stack, but experience with cloud-first architecture (AWS or GCP), microservices, React/Angular for web, and Flutter/React Native for mobile will help you get up to speed faster. Solid SQL/NoSQL design and REST/GraphQL experience are essential for the integrations piece. What I’ll look for in your bid Show me projects where you’ve already solved similar supply chain challenges or built logistics tools—detail the scale, your specific role, and any performance gains the client enjoyed.

...foundation across web, mobile and cloud. The server side will run on .NET (Core/Framework) and expose RESTful endpoints organised as micro-services. For the browser I’m happy with either Angular or React—pick whichever you are fastest with—and the companion mobile app will be written in React Native so we can share as much logic and styling as possible. The data layer can land on SQL Server, a NoSQL store or a mix of both; I’m open to your recommendation as long as the choice is justified and future-proof. Everything will be hosted on AWS or Azure, wired into a CI/CD pipeline (GitHub Actions or Azure DevOps are fine) so every commit ships automatically through test, staging and production. Clean code, SOLID principles, meaningful unit and integration test...

I’m ready to roll out Anthropic’s Claude across the company so it can shoulder two core responsibilities—data analysis and project management. To do that, the agent must read (and potentially write) directly against our in-house NoSQL database. Think Mongo-style collections rather than traditional SQL tables; all the information that drives our operations lives there, so smooth, secure connectivity is non-negotiable. Here’s what success looks like to me: • Claude can accept natural-language questions, translate them into NoSQL queries, and return clean, easy-to-read insights or visual summaries. • The same agent can create, modify, and track tasks in our existing project-tracking tool through an API/webhook, keeping teams updated au...

...clean UI/UX, and an AI layer that quietly automates routine user actions so the overall experience feels magical rather than mechanical. You may choose the tech stack you work fastest with—whether that’s Flutter, React Native, or a hybrid of React.js for the front end and Node.js or Python on the back—but the end result must be maintainable, secure, and ready to scale. A MongoDB (or equivalent NoSQL) datastore fits our real-time data flow well, and any existing APIs can be surfaced through well-documented REST or GraphQL endpoints. Key deliverables • MVP Android app with core automation feature live • AI/ML engine (Python or Node) trained and integrated • Secure backend, auth, and API layer • Basic admin console for metrics and conte...

...frontend → npm install → npm start • Confirm the API talks to MongoDB and that the browser loads without errors. • Walk me through the working copy (screen-share or short video). I will then pull the repo and test locally. Current functionality is limited to pure coding scaffolding—no auth, dashboards, or data visualisation yet—so please focus on a clean backend setup first. React, Node, and Mongo experience is essential. Looking ahead, once this baseline is stable we will layer in OpenAI features, Razorpay/Cashfree payments, and a refreshed UI, so build with extensibility in mind. Deliverables 1. Running project (frontend + backend) demonstrated live 2. Brief setup notes or README tweaks if anything differs from the commands above 3. ...

...reference images and design ideas to guide the concept. The overall tone I’m aiming for is modern, minimal, and scientifically grounded—with a balance between wellness aesthetics and credibility (not overly “spiritual” or generic). Design should be similar to the images I attached as references: half book black (before) and half book white (after). I would like to have a white figure sitting on the couch, binge eating, feeling sloppy on black background. On the other side, a black figure (similar to images attached) should be enjoying life, doing some happy activities like jogging, gym or similar on white background. Here’s what I’d like your help with: * Designing a front cover (and optionally a full cover if needed) * Translating my refere...

I’m finalising a nutrition-focused mobile product and now need the server side that can truly “think” before it answers. The stack is Node.js with Express and MongoDB, and the core requirement is an LLM pipeline that relies on retrieval-augmented generation, never hallucination. Here is what I need you to engineer: • A RAG workflow that pulls only verified nutritional data from my Mongo collections and feeds it to the language model, with additive analysis treated as first-class information. Accurate ingredient analysis is the single most important metric for success, so the retrieval layer has to be rock solid and testable. • User context handling: every response must factor in stored health profiles— allergies, chronic conditions, dietary g...

I have a collection of raw datasets that need a well-structured data model before we can move on to deeper analytics and reporting. At this stage I’m still weighing up whether a traditional SQL engine, a NoSQL store, or a cloud-native solution will suit the project best, so I’d value your guidance on the trade-offs while we shape the schema. Your task is to examine the source data I provide, recommend the most appropriate modelling paradigm, then design and implement a clean, scalable structure. Strong familiarity with relational techniques (ER modelling, normalisation, indexing strategies) alongside experience with denormalised or document-oriented patterns would be ideal. If a cloud platform such as BigQuery, Redshift, or Azure SQL turns out to be the right fit, I&rsq...
