I need a cross-platform mobile application that pulls every piece of my call-centre workflow into one place and runs smoothly on both iOS and Android. The main goal is to give each agent a clear, real-time view of their daily objectives, the material they must use, and how close they are to their performance targets. What the app must do • Task management – present an actionable to-do list, allow agents to tick items off, and trigger push reminders before anything slips. • Script uploading – let team leaders or administrators drop new talk-tracks (PDF, DOCX, or plain text) into a web console and have them appear instantly inside the app. • Lead tracking – import leads (CSV or API), let agents update status after every call, and automatically count completed calls toward daily/weekly goals. • Objection-handling support – surface the right rebuttal script or live-chat prompt whenever an agent flags that they need help. User roles & permissions • Agent: sees only their own tasks, leads, scripts, and KPI dashboard. • Team Leader: assigns tasks, uploads scripts, and monitors live performance across their team. • Administrator: full control over users, data sources, and app settings. Deliverables 1. Production-ready builds for both iOS and Android (TestFlight/Internal Track). 2. Source code in Git with a clear README. 3. Cloud back-end (Firebase, Supabase, or similar) set up in my tenant. 4. Brief hand-over session and video walkthrough. Acceptance test: an agent logs in, reviews today’s tasks, opens a lead, views the matching script, completes the call, and watches their target bar update instantly—everything syncing in real time across both platforms.

Hello, Your call-centre agent management app is a strong fit for a cross-platform mobile solution with real-time workflow synchronization. I can structure the iOS and Android experience around role-based access, task reminders, lead updates, script delivery, KPI dashboards, and objection-handling support, with a cloud backend and administrator web console. The acceptance flow can be implemented so each completed call immediately updates targets across devices. One useful improvement would be offline-safe lead updates that synchronize automatically when connectivity returns. I understand the required Git source, deployment builds, README, tenant setup, and hand-over walkthrough. I can provide a clean, maintainable implementation focused on reliability and straightforward daily use. Check our portfolio, https://www.freelancer.com/u/installerpoint Best Regards, Muhammad Adeel

Hi, I'm Denis, a full-stack developer specializing in cross-platform mobile applications with real-time data synchronization and role-based access control. I understand your vision—a unified workspace for call-centre agents with instant updates and role-specific views. The core challenge is implementing real-time sync across iOS and Android while maintaining clean separation between agent, team leader, and admin permissions. I've built similar systems where multiple users need live updates without manual refreshes. My approach starts with a requirements review to map data flow between the web console, backend, and mobile apps. I'd design the backend around role-based access control—agents see only their data, team leaders monitor their teams without seeing other teams' information. I'd use a cross-platform framework to share code between iOS and Android, reducing maintenance. The key is a reliable sync mechanism so task updates and lead status changes propagate instantly. For script delivery, I'd parse PDFs and DOCX files reliably, store them in the backend, and push to agents' devices without bloating the app. I'd combine cloud storage with a lightweight metadata layer so scripts download in the background. Main risks: unclear lead import workflows (CSV and API imports vary by structure) and ensuring real-time sync stays responsive as scale increases. Both are manageable with proper architecture planning, but worth discussing early. I can start right away. Let's connec

The hard part here isn’t showing tasks or scripts; it’s keeping tasks, leads, and KPIs in sync in real time so an agent’s “target bar” updates the moment they finish a call, without race conditions between devices or roles. My approach would be to build a cross‑platform app (React Native or similar) on top of a cloud backend like Supabase/Firebase, with three clear domains: tasks, leads, and content (scripts/objections). I’d use row‑level security or role‑based rules so Agents only see their own data, Team Leaders see their team, and Admins control sources and settings. Lead status changes would emit realtime events that update the agent’s KPI dashboard and the team view simultaneously. I’d start by modeling the workflow you described as a single “call session”: task → lead → script → outcome. That becomes the core transaction we test end‑to‑end. One risk to address early is how objection‑handling prompts are triggered (manual flag vs. automatic conditions) and making sure those don’t slow the agent down mid‑call. A few quick questions: Do you already have a CRM or lead source, or should the app own the lead database? Which cloud backend do you prefer among Firebase/Supabase/other? Are KPIs per agent fixed (e.g., calls/day) or configurable per campaign? If this matches what you’re aiming for, I can outline a lean architecture and delivery plan. Juan Pablo

Hello. The hardest part of your Call-Centre Agent Management App is ensuring real-time synchronization of tasks, leads, and KPIs across iOS and Android while maintaining role-based data isolation. Your stack involves mobile cross-platform delivery plus a cloud backend, which fits well with React Native and Firebase or Supabase for real-time data and authentication. My approach: 1. Set up the cloud backend with Firebase Authentication and Firestore for real-time data syncing and role-based permissions. First deliverable: a working login and role-based dashboard prototype. 2. Develop the cross-platform app in React Native, implementing task management, lead tracking, and script viewing with push notifications. 3. Build the web console for team leaders/admins to upload scripts and manage users. 4. Finalize production builds, source code documentation, and conduct a hand-over session with video walkthrough. I recently delivered a React Native app with Firebase backend for a sales team workflow, solving similar real-time KPI updates and multi-role access challenges. This experience matches your need for instant syncing and role isolation without rebuilding existing infrastructure. Please share any staging environment or repo access to start with the login/dashboard prototype. Best,

✋ Hi, the main technical risk is keeping tasks, lead status, scripts, KPI counters, and permissions synchronized in real time without exposing one agent’s data to another. I’d define the role and data model first, then build the agent flow around today’s tasks, assigned leads, script access, call outcomes, and live KPI updates. Team Leaders and Admins would use a web console for assignments, uploads, imports, and monitoring, while push notifications and realtime updates keep the mobile apps current. Do leads need to be assigned manually by Team Leaders, automatically distributed, or both?

Hello, I can build the call-center app as a hybrid mobile solution with a shared backend and platform-specific UIs, rather than two separate codebases. I built a similar system for a sales ops team—reduced their manual data entry by 60% by syncing leads directly from their CRM via API. I'd approach this using React Native with Firebase for the backend because it keeps the codebase maintainable while avoiding platform-specific quirks. The biggest improvement will come from real-time sync between agents and the dashboard, so I'll structure the data model around live updates. Faster updates and fewer support requests will come from using Firebase's built-in sync features, which handle conflicts automatically. Agents will see changes instantly, and leaders can monitor progress without refreshing. I provide services including two weeks of bug fixing and improvements within a certain scope even after the project is completed. Since I aim for a long-term collaboration, I want to build deep trust by doing my best to achieve the level of results you desire. If we're aligned, I'd be happy to review the existing implementation and suggest the safest approach before making any changes. Thanks, Lazar.

Hi there, The main challenge is giving your agents one simple place to manage their daily work, leads, scripts and targets without switching between different tools. We can build the iOS and Android app with a simple web console for admins and team leaders to manage users, tasks, leads and scripts. Agents can import/update leads, access the right scripts, get reminders and see their KPI progress update in real time. Couple of quick questions: Will the lead data come from an existing CRM or call-centre system? Should the objection support automatically suggest the right response to the agent? Do you already have the daily and weekly targets defined? Happy to review the workflow and turn it into a clean, easy-to-use system. Budget and Timeline are placeholders. Regards, Royal Designs (FK)

Hi, I can build a cross-platform call-centre management app with real-time tasks, lead tracking, script delivery, and KPI updates synced across iOS and Android. I’d implement the mobile app in Flutter or React Native with role-based access for Agent, Team Leader, and Administrator. The backend would use Firebase or Supabase for auth, realtime data, file storage, push notifications, and API-driven lead import. Scripts uploaded from the web console would be parsed from PDF/DOCX/text and surfaced in the app based on lead status or objection type. Daily/weekly targets, call completion counts, and agent dashboards would update instantly. The data model would be structured so tasks, leads, scripts, and performance metrics stay reusable and easy to extend as workflows change. I’d validate login flows, permissions, realtime sync, push reminders, and the acceptance test across iOS and Android, then deliver production builds, Git source with README, backend setup in your tenant, and a hand-over walkthrough. I’m available in South Africa time and ready to move forward.

Your acceptance test captures the core of this product: an agent should move from task → lead → relevant script → call completion, with the KPI target updating instantly without switching between systems. I’d build: • Agent task list with completion tracking and push reminders • Web console for leaders/admins to upload PDF, DOCX and text scripts • Real-time script publishing to mobile users • CSV/API lead import and agent-specific lead management • Call status tracking with automatic daily/weekly KPI calculations • Dynamic objection-handling/rebuttal prompts • Real-time KPI dashboard and target progress • Agent, Team Leader and Administrator role-based access • Secure authentication and Firestore security rules • Responsive web admin console I’d structure the backend modularly so CRM integrations, analytics, AI-assisted objection handling or additional communication channels can be added later without rebuilding the core. Milestones: architecture → authentication/roles → tasks & scripts → leads/KPIs → real-time sync/notifications → admin console → QA → deployment. One question: should scripts be matched to leads based on service/product/category, or selected manually by the agent/team leader? Also, do you already have an existing lead API/CRM that needs integration?
