I need a seamless, real-time bridge between our Shopify storefront and our in-house ERP, ACME. Whenever new inventory lands in the warehouse, a sale reduces available quantity, or a manual adjustment/return is logged in ACME, the exact stock level must instantly reflect on every Shopify product page without delay. Your job is to design, build, and deploy this two-way integration. My team can expose or consume REST/GraphQL endpoints on the ACME side, and I can generate API credentials in Shopify. Webhooks, polling safeguards, or a lightweight middleware layer are all acceptable—as long as every trigger above updates Shopify in real time and survives high-volume traffic. Deliverables • Production-ready integration code (language/tool of your choice) • Deployment or setu...

I have a mature JavaScript / Node.js codebase that now needs robust API connectivity. The goal is to wire in several external services—some exposed as classic REST endpoints, others as GraphQL—so the application can consume, transform, and surface that data seamlessly to the front-end. Here’s what I need from you: • Analyse the existing structure, identify the best touch-points for new service layers, and keep everything idiomatic to Node.js (Express, middleware, async/await). • Build out the integration layer for both REST and GraphQL calls, including token management, retries, and intelligent error handling. • Return clean, typed responses (TypeScript definitions or JSDoc) so downstream modules stay type-safe. • Write concise unit and integr...

I’m building an end-to-end conversational AI that handles text and real-time voice in four languages, guides users through staged enquiry and reservation flows, and syncs seamlessly with our existing systems and website. The core must expose a secure WebSocket API for live messaging, catalog synchronisation, and remote-tool protocols so my in-house apps can push or pull data without lag. Front-of-house, I need a portal-grade web stack: server-side rendered pages, a multilingual CMS, and a media pipeline that keeps images and audio optimised across devices. Back-of-house, the platform has to talk to the channels where our customers already are. For this phase I want native connectors for LINE OA, WhatsApp Business, Facebook Messenger, Telegram, Instagram, Google Business, TikTok, and...

I’m preparing to release a mobile-first social network that reproduces the familiar Instagram experience while leaving room for new features later on. The job covers the entire build cycle—from architecture and UI/UX to deployment—so I’m looking for someone (or a small team) comfortable owning the full stack. Core scope • Cross-platform mobile app (iOS and Android) built in React Native, Flutter, or a similar modern framework • Media handling: high-resolution photo and video capture, editing (basic filters, crop, trim), and cloud storage integration (AWS S3, Firebase Storage, etc.) • Dynamic home feed that can be switched between chronological and algorithmic once the ranking logic is defined • User accounts with profile pages, avatar up...

I want to desing a learning management system

I’m ready to move my high-yield investment program onto a dedicated mobile platform and need a full-featured app that runs smoothly on both iOS and Android. The core of the project is twofold: • Investment tracking – investors must see live performance data, historical yields, pending payouts, deposits and withdrawals in a clean, real-time dashboard. • User account management – seamless sign-up, KYC/verification, secure login, profile editing, two-factor authentication and an in-app support channel. You’re free to choose the most efficient cross-platform framework (Flutter, React Native or similar) as long as the final builds feel fully native, pass App Store and Google Play reviews, and are easy to maintain. REST/GraphQL skills are essential because t...
