Ruby on Rails Jobs

I am building a full-stack payment platform that sits as an application + orchestration layer on top of the Nigeria Inter-Bank Settlement System’s NQR and NIP rails. The core mandate is mass merchant enablement, while still giving consumers a frictionless QR experience. Scope The work covers everything from architecture through production rollout. You will create a scalable cloud back-end, merchant-focused web and mobile touch-points, consumer-facing apps for easy QR payment scanning, and an open API that third-party fintechs can plug into for value-added services such as data-driven lending and monetisation. Key requirements • Merchants are the primary users, so onboarding flows, settlement logic, and a dashboard that tracks volumes, fees and incentives must be rock-solid...

We are rolling out Zoho One company-wide and want the entire platform configured so our team can move straight from spreadsheets and disconnected tools into a single, streamlined workspace. Scope of work • Analyse our current processes and map them to Zoho One. • Configure the key apps—starting with CRM, Books and Projects—adding custom fields, pipelines, blueprints, automations and role-based permissions. • Integrate email, calendars and any essential third-party services (e.g., Office 365, Slack, website forms). • Build real-time dashboards and reports for sales, finance and project tracking. • Migrate legacy data only if we decide it is needed, ensuring clean, validated imports. • Produce short, clear documentation and run remote tr...

AI Voice Prompt Engineer (Real-Time Ordering System – NOT Chatbots) Body: We’re building a real-time AI phone agent for restaurants that takes full orders (like a human cashier). This is NOT a chatbot project. We need someone who understands: • real-time voice interaction (low latency) • turn-taking (no awkward pauses) • structured ordering flows (pizza, drinks, modifiers, upsells) • keeping conversations FAST, NATURAL, and ON TRACK What’s broken right now: • AI pauses too long • conversation loops / goes off track • responses feel robotic • ordering flow isn’t tight Your job: • design prompt structure + conversation flow • force clean step-by-step ordering (rails) • eliminate delays + overthinking responses &bu...

Project Details I need a small, well-structured Ruby service that exposes intuitive REST endpoints (GET, POST, PUT, DELETE). The core of the project is data-processing: requests will arrive, pass through my routing layer, and must then be propagated to specific, user-defined groups before a response is returned. Key points you can rely on: • Language: Ruby is not mandatory, feel free to use Rails, Sinatra, Hanami or another lightweight framework as long as the final routes stay clean and conventional. • External calls: the service has to consume several third-party REST APIs; graceful error handling and time-outs are important. • User layer: the API must already include Authentication and authorization plus basic User profile management so that each account can create and m...
