    Quiero trasladar mi página de inventario a una app Android nativa que trabaje exactamente con la misma base de datos: ni copias, ni sincronizaciones externas, sino conexión directa para que todo cambio se refleje al instante entre web y móvil. El usuario ya ingresa en la web con su correo y contraseña, así que el flujo de autenticación debe mantenerse idéntico en la aplicación. Necesito que la app reproduzca las funciones que hoy ofrece el sitio —gestión de productos, movimientos de stock, reportes y cualquier otra vista crítica— con la misma lógica de negocio y sin perder velocidad. Si en el proceso puedes añadir notificaciones en tiempo real o mejoras de usabilidad, serán bien recibi...

    I want to get up to speed on visualising Instagram hashtag activity as an interactive 3D network that updates in real time, so I can explore how clusters of conversation form and evolve. Basic counts or static charts won’t help me—I’m after a high-level, spatial overview that reveals relationships between hashtags at a glance. Here’s what I have in mind. You share your screen (or meet in a recorded call) and walk me through a streamlined pipeline: pulling public hashtag data from Instagram’s API or another compliant endpoint, streaming it into Python or Node, then projecting it with a WebGL or scene—Unity, Blender, or similar is fine if that’s your preferred stack.

    I’m midway through a software development project and now need to fold in a fully-fledged user authentication layer. The current codebase is stable and organised; what’s missing are the sign-up, log-in, password reset, and basic role-based access controls that will make the product production-ready. You’ll be working against an existing Git repo. I’ll grant access and walk you through the structure so you can slot your changes in cleanly rather than bolting them on. I’m open to the usual approaches—JWT sessions, OAuth, or any secure flavour you’re most comfortable with—as long as the solution is standards-compliant and easy for another developer to pick up later. Deliverables • Registration, log-in, log-out, password reset flows ...

    I’ve mapped out a process to apply to roles on LinkedIn, Indeed, and Glassdoor automatically and now need a polished n8n workflow that ties it all together. Please note before bidding Payment In Indian Rupees INR You’ll receive my CV, cover-letter templates, and the messaging formats I already use. Your task is to translate that into a clean, modular n8n setup that can: • pull each opportunity from a sheet or form, • generate the appropriate documents from my templates, • submit the application through the portal’s API or form endpoint, and • notify me once the application lands. Fixed Deadlines Standard fields are fine; no elaborate custom objects are necessary—just a rock-solid flow that I can tweak later without digging into code. ...

    I need my board to hand-off new tasks to the right people automatically as soon as a pulse is created. The goal is simple: whenever a new item appears, the system should look at predefined rules—team, project type, workload, or any other column I set—and assign the owner without manual intervention. Scope • Set up an automation (native recipe, integration, or custom API script) that triggers “Based on task creation.” • Map my existing columns to clear assignment logic so each new item immediately receives the correct owner. • Make sure the solution scales; I often add new team members and dropdown values, so modifying the rules later should be straightforward. • Provide a quick walkthrough or short Loom video so I can tweak the automati...

    I send 10-30 proposals a day across the major freelance platforms and have built a repeatable system that reliably triples the win rate when it is implemented end-to-end. I’m opening the door to one agency or freelancer who wants more closed deals but doesn’t want to keep hunting for the next short-term lead-gen trick. Here’s the arrangement: we work purely on a revenue-share basis. Every project you help me close through the system is split—no upfront fees, retainers, or hidden costs from my side. You will, however, cover the subscriptions for the few SaaS tools the workflow relies on, then configure and connect them. Expect to touch a lightweight CRM, proposal-tracking software and email/DM automation so you can stitch everything together and keep each touchpoint...

    I need a small, self-contained tool that lets me type a single email address, click “Verify”, and instantly learn—right on the same page—whether that address is hosted on Google Workspace or on Microsoft Outlook / Office 365. No file uploads or API hooks are necessary; the focus is a quick, manual, one-at-a-time lookup with a clear on-screen result. A lightweight web interface is fine, but I’m open to a command-line script if that delivers the same simple workflow. Behind the scenes you can rely on MX, SPF, or any other reliable signal; accuracy matters more than the specific method. Keep the UI clean: one input box, one button, and a neatly formatted result. Deliverables: • Complete, well-commented source code • Brief read-me explaining setup an...

    I need an Apify actor that crawls a single website and delivers two things for every page. You can use Puppeteer, Playwright or any other Apify helper library that keeps the run stable and fast. Here’s how I see the workflow: • I’ll share the target domain, URL pattern, and the exact text blocks I care about. • You create or fork an Apify actor in JavaScript/TypeScript, configure the request queues, handle pagination where needed, and store results in a dataset. • The final dataset should export cleanly to JSON and CSV, and the image URLs should be downloadable in bulk (a simple link list or an Apify key-value export is fine). • When the crawl completes, I want a brief README so I can rerun it myself later without touching the code. Acceptance crit...

    I want to commission a purpose-built high-frequency trading engine focused exclusively on stocks and driven by a momentum strategy. The system must ingest real-time streaming market data, react in microseconds, and execute orders with minimal slippage. Key expectations • End-to-end architecture: ultra-low-latency market data capture, signal generation based on momentum indicators, smart order routing, and risk controls. • Exchange connectivity: direct API or FIX gateways to major equity venues; the code has to be exchange-agnostic enough to let me plug in additional venues later. • Deterministic performance: consistent round-trip times under heavy load, with benchmarks and profiling evidence. • Safety nets: position limits, kill-switch, and detailed logging tha...
