Ruby on Rails Jobs

I need a custom plugin for my Shopify store that focuses solely on inventory management. The app must tap directly into Shopify’s API to keep stock levels accurate in real time and alert me whenever an item reaches a predefined threshold. Core scope • Real-time rastreamento de estoque through the Shopify API, updating quantities across all product variants without manual refreshes. • Notificações de reposição via email and optionally push or SMS when stock falls below a configurable level. Key details – Built for the current Shopify App Bridge and Admin API versions. – Clean, well-commented code in either Node.js or Ruby on Rails (I’m flexible if you prefer another stack that is Shopify-friendly). – All configu...

I run a steel-trading company and want to weave ChatGPT into every customer-facing and decision-making point of the business. The goal is to have one cohesive solution that handles customer inquiries and support, sparks qualified sales leads, and continuously scans market data to deliver clear price-trend insights—essentially covering all of the above functions mentioned. Here is what I have in mind: • A responsive chat widget (web & mobile) that fields customer questions, checks stock/price data we supply, and routes complex issues to my team. • An automated lead-generation workflow that captures prospect intent from chat or web forms, scores the lead, and pushes it into our CRM. • A market-analysis module that pulls public steel indices or our proprietary ...

I’m building a Python-powered Lead Management CRM and now need a React specialist to bring the user side to life. You’ll craft a vibrant, colorful interface from scratch (no wireframes exist yet) and wire it up to my already-developed REST APIs. is my go-to for the basic analytics, so experience there is important. What I need you to deliver: • Responsive login, dashboard and lead list pages • Forms to add, edit and update leads, including status changes (new, contacted, converted, etc.) • At-a-glance statistics and visualizations inside the dashboard • Clean component structure, sensible state management and clear API integration hooks The project moves fast—ideally finished in about two to three weeks—so regular check-ins and a shar...

The codebase is a React front end that relies on Supabase for authentication, data storage, and real-time updates. A series of stubborn bugs have crept in—misfired auth callbacks, occasional data mismatches after writes, and visibly broken UI states when the websocket drops. Your first mission is to isolate and eliminate those issues so the app runs cleanly, with no console errors and all existing unit tests green. Once the core bugs are gone, I’d like a quick pass on the database schema (a couple of tables need index tweaks and a foreign-key adjustment) and help preparing a production deployment workflow. The stack is already wired to GitHub; I deploy to Vercel, but I’m open to your preferred routine as long as rollbacks are painless. Everything needs to be wrapped up ...

I need a 1099 contractor who can commit 20-40 hours a week to split their time between a brand-new Rails API with a React front-end and an older legacy Rails monolith. Both codebases matter equally to the business, so you’ll be jumping back and forth—building fresh features in the greenfield project while keeping the legacy app functional and stable. We’ll kick things off with new feature development. The exact specs are still loose, so I’ll rely on you to help shape requirements, challenge assumptions, and translate rough product ideas into well-scoped user stories. Clean, well-tested, idiomatic Ruby and modern React are the baseline; RSpec, Jest/Testing Library, GitHub pull-requests, and CI/CD (we use GitHub Actions) are part of the day-to-day workflow. Delivera...

I’m gearing up for a new promotional push across Instagram, Facebook, and X, and I need a fresh set of eye-catching social media graphics that flow naturally from a brand-new logo. Here’s what I’m after: • A modern, versatile logo delivered in vector format (AI/SVG) plus web-ready PNGs. • A batch of platform-specific promo graphics—at minimum Instagram square & story, Facebook post & cover, and an X post—each templated so that future text swaps are easy. • Consistent colour palette, typography recommendations, and simple usage notes so everything ties together. Please build everything in Adobe Illustrator/Photoshop (or compatible tools) and hand over layered source files alongside ready-to-post exports. I’ll provide any copy, ro...

I am starting a modern web application and have already committed to React for the entire front-end experience. The design calls for a clean component architecture, responsive behaviour across desktop and mobile breakpoints, and smooth state management—so expect heavy use of hooks, Context, and, where appropriate, Redux Toolkit. On the server side I’m still weighing options. If you prefer Node.js, Django, or Ruby on Rails, let me know how you would structure the API layer, handle authentication, and manage data persistence; the final decision will be based on whichever stack you can demonstrate will scale cleanly and deploy easily to a cloud host such as AWS or Vercel. Key deliverables • Production-ready React front-end (TypeScript welcome) • REST or GraphQL API...
