    Necesito una animación en formato Lottie JSON destinada a un tótem publicitario con pantalla táctil. El estilo debe ser minimalista: líneas limpias, pocos colores y movimientos suaves que no distraigan del objetivo principal. Comportamiento deseado: 1. Al tocar la pantalla, la animación se activa (touch to start). 2. De inmediato debe generarse y mostrarse en pantalla un número aleatorio claramente legible. 3. Tras unos segundos, la animación vuelve a su estado inicial, lista para el próximo usuario. Entregables esenciales: • Archivo Lottie JSON optimizado para looping continuo. • Breve guía de integración (cómo embeberlo en la aplicación del tótem y mapear el evento táctil). &...

    I need a compact trading bot that plugs into Pocket Option, tracks my your strategy, and texts me the moment every condition lines up. The bot must monitor three data streams at once—price trends, a defined set of technical indicators, and live market news—then run its alignment check on a fixed five-minute loop. When all three pillars confirm the same direction, it should fire off an SMS alert to my phone instantly and reliably. Key points you’ll handle: • Direct integration with Pocket Option (API or web-automation, whichever is safest and within their terms). • Modular indicator engine so I can tweak or swap indicators later without rewriting the whole bot. • Lightweight news feed parser that can pull headlines or sentiment scores and feed them in...

    Description: We are looking for a skilled Python developer to build a secure browser automation script for managing multiple independent data sessions. Project Scope: We already have a basic script that launches a browser with specific settings (similar to Playwright/Puppeteer with headless=False and geolocation support). We need you to: 1. Integrate Proxy Management: Connect our system to external proxy providers (supporting HTTP/SOCKS5, residential, and mobile IPs). 2. Implement Session Isolation: Ensure each launched browser instance has a completely separate environment (cookies, cache, local storage). One session must never interfere with another. 3. IP Assignment Logic: Build a system where each session is assigned a specific dedicated proxy (sticky IP) that remains consistent f...

    I want a self-contained software agent that, when I feed it the name or domain of a medium-sized enterprise, automatically pieces together the company’s full organisational chart and returns a verified corporate email and number for every person it finds. The agent may explore open data reservoirs—our internal databases, public directories and employee social profiles—but it should not rely on any authenticated endpoints, API keys or user log-ins. You are free to choose the language and stack, though Python plus libraries such as Scrapy, Beautiful Soup, Selenium or similar web-automation tools would make sense. The final output needs to be delivered in both machine-readable (JSON or CSV) and human-friendly form: a hierarchical tree or graph that clearly shows reporting ...

    I need a seasoned PHP developer to design and build a clean, well-documented API from the ground up. The project centres entirely on backend logic—there is no front-end work—so your focus will be creating efficient endpoints, solid authentication, and clear JSON output. Here’s what I have in mind: • Code in modern PHP (8.x preferred) and follow PSR standards. • Use a framework or micro-framework you’re comfortable with—Laravel, Lumen, Slim, or even plain Composer packages are fine—as long as it stays lean and easy to maintain. • Include token-based authentication, structured error handling, and basic rate limiting. • Provide concise documentation (endpoints, parameters, responses) plus a Postman or Insomnia collection so I can...

    I need a solid PostgreSQL-backed RESTful API to drive the Solar TwinPro web application. Your task is to design the database schema and expose clean, versioned endpoints that cover full CRUD functionality for each core resource in the system. The web front-end will consume JSON, so consistent status codes and clear error handling are important. Please structure the project so it can be deployed easily (Docker preferred, but I am open to other simple approaches) and include concise documentation; an OpenAPI/Swagger spec is ideal so the front-end team can plug in without guesswork. Deliverables • PostgreSQL schema (DDL) and seed data • REST endpoints covering create, read, update, delete for all defined entities • Environment and run instructions (e.g., Dockerfile or...

    Autoamtion and web scraping

    I’m looking for a fast-turnaround solution that takes the repetitive data-extraction work off my hands entirely. The goal is simple: I give you a set of target pages, and your script logs in if needed, navigates through the required paths, grabs the specific fields I specify, and deposits the results in a clean CSV or JSON file ready for downstream use. I don’t want a one-off scrape; I need true process automation. The code should be reusable, easy for me to schedule, and resilient to minor layout changes. Python with Selenium, Playwright or a headless browser is fine—as long as it’s well commented and comes with a quick README so I can run it on my own machine or a small VPS. Because I need this ASAP, clarity is critical. Once you’re onboard, I’ll...

    I’m enhancing an existing PHP application and now need an experienced developer to wire in several third-party services. The core of the job is to analyse each provider’s endpoint requirements, extend or refactor the current codebase where necessary, and make sure the new integrations run smoothly alongside what is already in production. You will be working with modern PHP (object-oriented, namespaced) on a LAMP stack, so familiarity with RESTful requests, webhooks, JSON handling, and robust error logging is essential. Security is a must—token management, input sanitisation, and graceful failure states all have to be considered from the outset. I’ll give you access to the repository, environment details and any documentation the vendors supply. Your work should pl...
