    Saya membutuhkan sebuah bot WhatsApp yang dapat menjawab pesan masuk secara otomatis selama 24/7. Fokus utamanya adalah merespons pertanyaan umum dari calon pelanggan, sehingga saya tidak harus selalu memantau ponsel.

Teknologi apa pun dipersilakan—Baileys, Venom, WWebJS, atau integrasi WhatsApp Cloud API—selama stabil dan tidak membutuhkan server berspesifikasi tinggi.

    I already have a web-based “snap and send” tool for real-estate agents that lets them capture and edit property photos, pay, and instantly forward everything to our backend. The Node.js API is live on Railway, so what I need now is a React Native + TypeScript expert who can wrap that same workflow into a smooth, production-ready iOS app. Here is what you will be working with and what I expect: • Core flow: open camera, take a shot, or select from the gallery, then allow users to crop, resize, annotate, and highlight before sending the images to the existing endpoints. • Payments: hook the checkout step to Stripe so agents can pay by card inside the app, exactly as they do on the web. • Backend: all endpoints, auth, and business logic are done; you just cons...

    Real-Time Italian Price Monitor

    I run a deals community that focuses on electronics sold through a popular Italian e-commerce site. I need a small, always-on tool that watches the product pages I feed it and pings a Discord channel the moment a price changes. Real-time means seconds or, at most, a couple of minutes after the site updates—daily or weekly reports are not enough. You are free to build this in Python (requests / BeautifulSoup, Selenium, Playwright) or Node.js (Puppeteer, Playwright). It just has to run reliably on a Linux VPS, survive Cloudflare or other anti-bot hurdles, and keep lightweight logs so I can see when something fails. Core flow I have in mind: • The script reads a JSON/CSV list of electronics URLs. • On each cycle it grabs the current price, compares it to the last stored va...

    Necesito trasladar una base de datos MySQL de 1,5 GB que hoy corre en un VPS de DigitalOcean a un nuevo servidor VPS en Hetzner. La conexión actual usa certificados SSL/TLS y quiero conservar ese mismo esquema de autenticación en el destino. El plan es mantener la instancia de DigitalOcean encendida, clonar la BBDD a Hetzner, probarla varias semanas sin replicación en tiempo real y, cuando todo esté validado, desactivar la original. No busco sincronización automática; me basta con que la copia de Hetzner funcione de forma independiente para validar consultas, rendimiento y estabilidad. También necesito la configuración completa del entorno Ubuntu/NestJS en Hetzner: instalar Node.js, PM2, Nginx (o el proxy que aconsejes), variables...

    I need a business-grade website whose sole purpose is to let visitors convert and edit PDFs directly in the browser. The site must be responsive, fast, and secure. The workflow is simple: a user uploads a PDF, selects the action—conversion to Word, Excel, image; basic editing such as merge, split, or rotate—and receives a processed file for download. Everything happens online with no local software required. You are free to choose the stack (React, Vue, Svelte, or a lean HTML/CSS/JS front end paired with Node, Python, PHP or any performant back-end) as long as you specify the conversion engine you’ll use—pdf-lib, Ghostscript, LibreOffice headless, or a third-party API are all acceptable options. Just be clear about any licensing costs so I can budget for them. ...

    I need a seasoned full-stack developer to take a fresh, objective look at our live ticketing and checkout platform built with Node.js (Express), React / React Native, PostgreSQL, and Stripe.

What I’d like you to do • Pull the entire repo (API and both web / mobile front-ends) and spin it up locally or in a sandbox. • Walk through the structure, security posture, and general maintainability—package versions, linting rules, folder conventions, test coverage, and any potential React Native quirks. • Check PostgreSQL migrations and query performance, making sure schemas line up with the code. • Verify that our d...

    I’m building a lightweight digital task manager whose core strength is clean, project-level categorisation.

    I’m putting together a compact crypto-casino focused on two core games—Crash and Dice—and I want it live within four weeks. The front end should be built in React and styled with Tailwind (or an equally lightweight alternative) to deliver a clean, dark, fully responsive interface. On the server side I prefer PHP, with MongoDB handling data storage. Key requirements I need you to cover: • Provably-fair logic for both games, with public seeds and verifiable hashes. • Crypto deposits and withdrawals in USDT, TRX, and LTC. You may integrate CoinPayments or craft a custom wallet module; either approach must support automated callbacks and manual overrides. • A full admin panel where I can adjust RTP percentages, enable/disable the faucet and rain features, view...
