Ya tengo un flujo n8n en funcionamiento que coloca operaciones simples, pero ahora necesito implementar lo que llamo "Opción B": gestión de estado completa, soporte para pedidos complejos y un interruptor de apagado confiable. La integración debe hablar directamente con la API de Charles Schwab, por lo que la experiencia probada con ese corredor específico es esencial. Lo que queda por construir • Lógica de estado: cada posición abierta y pedido pendiente debe rastrearse continuamente, con actualizaciones de estado guardadas en mi instancia de PostgreSQL y empujadas a Telegram en tiempo real. • Pedidos complejos: el flujo tiene que crear, monitorear y, cuando sea necesario, cancelar pedidos de OCO (Uno Cancela Otro) utilizando l...

I need a full-featured, production-ready lottery website built from the ground up. The public-facing side must let players register with either classic email/password or convenient social-media login, purchase single lottery tickets, fund a wallet through popular gateways, and watch live draws with instant result updates from any device. On the back end, the admin console should give me granular control over everything: creating and scheduling draws, editing prize tables, approving or refunding payments, managing user balances and commissions, generating downloadable reports, and updating on-site content without touching code. Role-based access, audit logs, rate-limiting, and encryption at rest and in transit are non-negotiable so we stay compliant and secure. Stack flexibility is fine&m...

I want to launch a simple, purpose-driven web portal that lets people list their old textbooks so students can easily browse what is available and request the copies they need. The heart of the site is a public catalogue—every book should appear with its title, author, short description, and condition, and visitors must be able to narrow their search quickly through clear category filters (subject, grade level, language, etc.). Anyone who wants to add or manage a book will create an account; once signed in, they can post new listings, upload cover photos, edit details, or mark an item as already sent. An administrator area should give me full oversight so I can remove inappropriate posts, reset passwords, and pull simple usage reports. Please build this on a modern, well-supported ...

Project Title: Web Developer Needed: Color-Matching Web App (Using CIELAB & Delta E 2000) Project Overview: I own a textile/thread business with a shade card of 700 unique colors. I need a lightweight, mobile-friendly web application where my staff can take a picture of a fabric sample, and the app will instantly tell them which of our 700 thread numbers is the closest match. Important Note on Accuracy (Please read carefully): I am looking for a developer who understands basic color science. You cannot use simple RGB Euclidean distance for this match. The math must convert the camera's RGB input into the CIELAB color space and use the Delta E 2000 (CIEDE2000) formula to find the closest match. I will be using a controlled lighting environment (an LED lightbox) to take the photos, ...

I need help wiring external APIs into our existing dashboard so the data we monitor appears in near-real time. The front-end is already built; what’s missing is the secure backend logic that authenticates, pulls, and formats the dashboard data before handing it to the UI. The application currently runs on Node.js and Express with a PostgreSQL store, but I’m open to Python (FastAPI) if that accelerates delivery. Whichever stack you choose, clean code, clear documentation, and environment-based configuration are essential. Deliverables • Integration code that connects to the chosen APIs and returns JSON ready for the dashboard • Any middleware or helper modules needed for authentication, rate-limits, and error handling • Step-by-step setup instructions in a...

I need help moving my existing Turso-hosted SQLite database—currently well under 1 GB—into PostgreSQL so it plugs cleanly into my tech stack ( on the front end, Payload CMS on the back end). The project covers three parts: designing an equivalent Postgres schema, transferring all data without loss, and updating the Payload/ configuration so the application boots immediately against the new database. You will need to: • Map the current tables, relationships, and data types to Postgres equivalents • Run (or write) the migration scripts and verify record counts and data integrity • Adjust Payload CMS settings and any environment variables in the app to point to Postgres • Provide a short hand-off note explaining the changes and any future maintenance ...

I need a full-stack developer who can build a complete Satta Matka play platform from the ground up. The stack I’m comfortable with is HTML for markup, PHP with the CodeIgniter framework on the back end, and Node.js for any real-time components. The finished site should feel as snappy as a native mobile app, so please keep performance optimisation, responsive layouts and PWA techniques in mind from the start. Core functionality I must see on day one: • Live game results that update instantly without a page refresh, preferably via WebSockets or an equally fast Node.js solution. • A secure user-registration and login system that supports sessions, password hashing and basic 2-factor expansion later on. • A fully working betting system where users can place, track an...

I’m moving the wider DeFi & Web3 project forward by tackling the staking layer first, and I need a developer who can take it from architecture to main-net launch. The immediate goal is to deliver staking contracts that support our own native token alongside key stablecoins, all managed through multiple independent pools that can run different APRs and compounding rules. Here’s what the first milestone looks like: • Write and test Solidity (EVM-compatible) contracts for multiple staking pools. • Enable deposits, withdrawals, and reward calculations for both native tokens and stablecoins. • Build a simple dashboard or CLI so I can monitor TVL, pool-specific metrics, and user positions during testing. • Provide unit tests, coverage reports, and a b...

I have a ten-page source text that I need converted into 384-dimension embeddings and stored in a vector database so I can run fast semantic queries against it. After that, I want Claude Sonnet 3.5 deployed in my AWS account (EC2 or an equivalent managed service is fine) and wired up to those embeddings so that users can chat in plain text and receive interactive language-learning guidance based on the content. Here is the workflow I have in mind: • Generate 384-dimensional embeddings for the entire document, verify their quality, and load them into a persistent vector store (Pinecone, Amazon Kendra, or Faiss—whichever you prefer and can justify). • Spin up Claude Sonnet 3.5 in AWS and expose it through a simple web front end or an API endpoint; no voice features are re...

I want a clean, self-contained docker-compose stack that spins up a brand-new Immich instance on a fresh server. The goal is to be able to clone the repo, run docker-compose up -d, and have Immich reachable on its default port with all volumes, environment variables, and network settings correctly wired. Key points • This is for a first-time installation, not an update or a troubleshooting exercise. • I do not need Redis, Nginx, or any other companion containers right now—just the core Immich services and the database it requires. If PostgreSQL is still the standard backend, please include it; if Immich now supports other options, feel free to suggest the simplest stable choice. • Provide a concise README or inline comments explaining any configurable values (.e...

I have a small React + Node.js/Express web app that needs a quick round of improvements: 1. The user-profile screen is not persisting updates. I need the underlying bug identified and resolved on both the frontend state layer and the Express API so the data reliably saves and reloads. 2. Please introduce a simple dark-mode toggle. I’m flexible on placement—choose a spot that feels natural in the existing UI, wire it into the current React state management, and make sure styles switch cleanly without page reloads. 3. Confirm everything looks and behaves correctly on common desktop breakpoints and mobile widths. A light round of responsive tweaks is fine as long as the layouts stay intact. Technical stack you’ll touch: • React (functional components, hooks) &bull...

I’m creating a browser-based quiz game that plugs into the Zoom Video SDK so contestants can play while a live audience watches and interacts. The game must run entirely on the web, support up to ten simultaneous players, and present questions grouped by sections rather than one at a time. Here’s the play flow I have in mind. Players join a private lobby through a link, take their seats (maximum ten), and wait until I start the round. When I launch a section, every contestant sees that block of multiple-choice questions (options A-D). They answer, I close the section, scores update in real time, and the next section appears. A live leaderboard should be visible inside the Zoom share so both players and audience can follow the standings. What I need built: • Web front end...

I run a fleet of 3000-plus smart water dispensers spread across multiple client locations and need a single web application that lets me see what is happening at each device the moment it happens. The core of the build is a full-stack solution: a React / front-end talking to a Node.js or FastAPI back-end, with MQTT handling the ingestion stream. Data persistence will live in PostgreSQL with the TimescaleDB extension so we can store high-frequency time-series readings while still keeping queries snappy; Redis will sit in front for real-time queues and caching. The most critical values that must update in real time are TDS and Temperature, though the schema should already accommodate pH, turbidity and any future metrics so I can turn those on without major refactoring. Multi-tenancy is ...

I need a professionally designed, fully responsive e-commerce website dedicated to selling digital products only—think downloadable files such as e-books, templates, or software keys. Because the store must be custom-built rather than relying on Shopify or WooCommerce, it should be tailored end-to-end to my brand, conversion flow, and future feature ideas. Beyond clean UI/UX, the site has to handle secure user accounts, instant file delivery after payment, license-key generation (if needed), and an intuitive admin dashboard where I can upload new products, track sales, and issue refunds. Integrations with Stripe and PayPal are a must, and I’d like the codebase to be easy to maintain—modern stacks such as Laravel, Node/Express, or a lightweight Python framework all work f...

I’m running a transport management system that’s already live on an Ubuntu VPS, served through Nginx and kept alive with PM2. The stack is React + Vite on the front end and Node.js on the back, and it’s functioning well except for one critical area: printing and RTL layout. Here’s what I need you to tackle: • Treat A4 as the baseline paper size and make every printable view line up perfectly—margins, headers, footers, stamp area, and an auto-generated QR. • Apply Arabic RTL rules consistently across all pages, not just a subset, so customers switching between LTR and RTL never see a jumpy interface. • Switch the system’s main print typography to clean, well-sized Arial, adjusting weights and sizes so both on-screen and printed text r...
