I am ready to move from concept to a working MVP and want every core layer built in one coordinated sprint. The product will be available on iOS and Android first, with a lightweight web dashboard for administration and analytics. Design I need a completely custom look and feel—no off-the-shelf Material or Flat themes. Your first task will be producing high-fidelity UI/UX mock-ups for the mobile apps and the web dashboard, then translating them into workable front-end components. Mobile prototype The prototype must run natively on both iOS and Android. It should already support: • Secure user authentication (email/social) • Push notifications (device token management included) • In-app purchases for digital content Backend & data layer Please archi...

For a set of consumer-facing mobile products built with Flutter 3.x and Dart, I need an experienced developer who can dedicate four focused hours every day. The daily work revolves around extending existing features, refining clean and responsive UI, and wiring screens to RESTful endpoints; familiarity with Firebase (Auth, Cloud Firestore, FCM) will give you an edge because several modules already rely on it. Workflow • You’ll receive clearly scoped tickets each day, push code to our private GitHub repo, and open a pull request with concise commit messages. • Communication happens in Slack; a short stand-up text update at the end of your session is enough. • All code must compile on both Android and iOS without warnings and follow our simple dart lint rules. Wh...

I’m ready to add a dedicated Django developer to my remote team for a full-time, 8-hour-per-day schedule. The work revolves around hands-on Django and Python coding, so deep, current expertise in both is my top hiring criterion. All services you build or maintain are exposed as RESTful APIs, so I need someone already comfortable designing, documenting, securing, and scaling those endpoints. You’ll also manage our CI/CD pipeline: pushing code through automated tests and deployments with tools such as GitHub Actions, Jenkins, or similar. About ten percent of the role touches the front-end—simple template tweaks or light JavaScript—while the rest is pure backend work, including routine deployments and keeping the architecture clean and maintainable. The position is f...

Optimize and fix performance issues in an existing Flutter mobile application for Android and iOS. Tasks include improving app speed, reducing lag, fixing UI/rendering issues, debugging crashes, optimizing API and state management performance, and preparing production builds for deployment. Experience with TestFlight, Apple App Store, and Google Play Store publishing, release management, Firebase integration, and production-ready Flutter applications.

I have a complete set of Figma screens for our new corporate website and now need them brought to life. Your main focus will be twofold: building a pixel-perfect, responsive frontend in React with clean HTML, modern CSS and vanilla JavaScript where needed, and wiring that UI to a robust Node.js backend. On the frontend you’ll translate every component from the designs, set up routing, state management and animations where the mock-ups call for them, and be sure the experience remains consistent across Chrome, Firefox, Safari and Edge. Accessibility and mobile responsiveness are non-negotiable. On the backend you’ll create well-structured Node.js services that expose RESTful APIs, connect to our existing data sources, and handle integrations such as CRM and email gateways. I&r...

I run Workday as our HR backbone and already automate a number of processes with Workato recipes. The next step is to plug Adobe Learning Manager into that same flow so every employee record, enrollment and completion event moves cleanly between the two systems without manual effort. Here is what I need you to wire up: • Course enrollment sync • Completion status updates • User data management You should be comfortable working with Workato connectors, Workday Web Services, and the Adobe Learning Manager REST APIs, building reusable recipes, handling OAuth tokens, and mapping custom fields that don’t line up out-of-the-box. I’ll pass you access to our lower-environment tenants first; once the integration is stable, we’ll promote it together to produ...

I need to add direct WhatsApp messaging to our in-house ERP so that I can trigger posts to existing WhatsApp groups right from the dashboard. The key requirement is that every message—whether plain text, image, video, or other attachment—must show my personal phone number as the sender inside the group, not a generic business account. Scope • Analyse which officially supported (or reliable alternative) APIs or gateways can post to WhatsApp groups while preserving the original sender ID. • Design a lightweight integration layer that my ERP can call through REST or webhooks. • Build and test endpoints for sending both text and multimedia. • Provide clear setup notes: token management, device pairing, rate limits, and any compliance considerations. &...

I’m expanding a set of business-critical automations and I need someone who already knows n8n inside out. You’ll take the lead on three fronts: • Designing and refining advanced workflow automation that can scale without breaking existing processes • Building custom nodes when the default palette can’t cover a requirement, keeping the code clean, documented, and merge-ready • Connecting n8n to a variety of external services—REST and GraphQL APIs, webhooks, and OAuth flows—so data moves seamlessly between our tools I’ll share a detailed mapping of each process, sample payloads, and access to a staging environment as soon as we start. Your work is considered complete when every workflow is running error-free in production, the custom n...

I want a clean, responsive web application where logistics companies compete in an open-bid environment for loads or routes. The heart of the platform is the user bidding system, so every screen, workflow, and data model should revolve around real-time, transparent bidding. Important Note: While applying, you must include the links to at least 5 comparable web applications you have created. These sites much be functional. Core flow • A shipper posts a load request. • Verified logistics companies view the request, see the current best offer, and submit their own bids in real time. • When the countdown expires, the shipper can award the job through the dashboard. Key requirements • Role-based accounts (shipper, carrier, admin) with secure sign-up and 2-fac...

I’m launching a web-based social network and need an experienced developer to take it from concept to a live, scalable platform. The core build must include secure user registration and login, a real-time activity feed, follow/friend functionality, direct messaging, notifications, profile editing, and a simple admin dashboard. Responsive design is essential so the service feels seamless on phones, tablets, and desktops. I’m flexible on the stack, though a modern front-end framework such as React or Vue paired with a robust back end (Node.js, Django, or similar) and an SQL or NoSQL database would be ideal. Clean RESTful (or GraphQL) APIs are important because I plan to introduce a companion Windows desktop client later, so please architect with that future integration in mind. ...

Necesito replicar nuestro actual programa de gestión en una nueva instancia basada en Strapi. El sistema original corre en filemaker y deseo mantener ese enfoque en cloud, garantizando la misma lógica de negocio y flujos de trabajo, pero aprovechando las ventajas de Strapi (Node.js, API REST/GraphQL, roles y permisos nativos). Al reconstruirlo, deben quedar operativas las siguientes áreas: • Gestión de usuarios • Generación de informes • Control de inventario • Gestión de presupuestos • Facturación (verifactu) Además, los primeros módulos que necesito totalmente integrados son Gestión de usuarios y Generación de informes, sobre los que validaré la fidelidad del clon antes...

I’m building a brand-new web application under a fast-moving startup and I need one dedicated engineer to own the full stack from day one. We operate on California (PST) business hours, so you’ll work those hours alongside me and the design team, collaborating live through Slack, GitHub and Zoom. The core of the product is a React-driven front end, coupled with whatever back-end stack you’re most productive in—Node/Express, Python/FastAPI, or a comparable RESTful setup. You’ll start with green-field architecture decisions, set up CI/CD, wireframes to working screens, database schema, APIs, automated tests and production deployment. This is a full-time, monthly-salary role and I’m hiring an individual developer only—no agencies or teams. Automa...

I need a full stack developer and Android app specialist to create a falls management social care application. We’re building a system that places NFC tags where care happens — on residents’ mobility aids (where present), bed-frames, and door-frames, with an optional consent-driven silicone wristband. Staff tap their phone and instantly see a traffic light status (Green/Amber/Red) with key clinical flags. The status is set by senior nursing staff via a guided MFRS-based clinical workflow. We’re seeking proposals to build this in three potential phases. You may quote for any one phase, multiple phases, or all three. Project context The problem Falls in UK care homes drive 255,000 emergency hospital admissions per year and cost the NHS £2.3 billion. The single b...

Tengo mi app Lovable casi lista, pero aún quedan varios detalles técnicos antes de publicarla. Busco a alguien que pueda cerrar este sprint y dejarla preparada para producción: 1. Conectar la API de la base de datos de artículos científicos que ya tengo seleccionada, mostrando los resultados dentro de la interfaz actual. 2. Configurar el plan de pago como prueba gratuita con opción de compra: el usuario disfruta X días sin costo y, al vencer, se activa el cobro recurrente que definamos. 3. Restringir ciertas funciones para estudiantes: solo quienes se registren con carnet y datos académicos podrán acceder a esas secciones. 4. Verificación de correo mediante código numérico enviado al email durante el regis...

I’m building a custom web application in PHP using the latest stable version of Laravel. The core scope includes: • Robust user authentication (registration, login, password reset, role-based access) • An intuitive content editor that lets non-technical users create and format pages or posts • Media management for images, documents, and video with basic cropping, resizing, and organized folders Beyond the core, I also need social-media integrations (think single-sign-on with Facebook/Google and the ability to pull or push content to selected platforms) plus connections to external APIs that will supply data feeds to the app. No payment gateway work is required right now, but the codebase should be clean and modular so we can bolt that on later if needed. You...

The mobile app for this lending platform is already live, and every middleware endpoint has been built and tested in Spring Boot. Now I need the browser-based front end. Your task is to turn my finished Figma designs into a production-grade Angular application that mirrors the mobile experience and runs flawlessly on modern browsers. Around 20 screens are required to be developed based on Figma designs we have already ready You will build responsive components, hook them into our existing REST and WebSocket endpoints, implement JWT authentication (including silent refresh), and deliver a fully tested codebase. Pixel-perfect fidelity with the designs, smooth real-time updates throughout the onboarding flow, and clean, maintainable TypeScript are critical. Deliverables • Complete An...

From Pakistan or India we need Python Developer for long term and at low budget. I have a brand-new, web-based project that needs to be coded in Python from the ground up. The scope is intentionally lean so a junior-level developer can comfortably handle it while still touching the core pieces of a modern web app. The stack is flexible: Django or Flask are both fine, as long as the final codebase is clean, documented, and easy for me to pick up later. A lightweight front-end (simple HTML/CSS or any minimal JS you prefer) is all that’s required; the emphasis is on solid back-end structure.

My Django-based website already handles sign-ups, log-ins, and a full content management flow; now I need the same experience packaged as a cross-platform mobile app written in Flutter. The backend is ready—Django REST endpoints (token or session auth) will be available—so the bulk of the work sits in the Flutter front end, wiring it cleanly to those APIs and presenting a smooth, native-feeling UI. Key objectives • Reproduce the existing user account system, including registration, secure authentication, password reset, and profile editing. • Pull, display, and allow basic CRUD actions for the site’s managed content—articles, images, and any custom models exposed through the API—mirroring the website’s logic and permissions. • Follo...

Preciso desenvolver um Módulo de Distribuição de Energia com 18 saídas, inspirado nos PDM15 que já uso como referência interna. O objetivo é assegurar três funcionalidades cruciais desde a primeira versão: proteção contra sobrecarga em cada canal, monitoramento remoto em tempo real e controle individual de todas as saídas. Quero comandar e visualizar tudo numa interface web amigável, acessível tanto em desktops quanto em smartphones; portanto, a parte de firmware e a camada de software devem expor servidores HTTP-REST ou WebSocket que facilitem integrações futuras. Ainda não defini requisitos de compatibilidade com sistemas externos, então o código e o hardwar...
