A Warm Hello! We are readily available to start working on this project! We will provide you secure transaction platforms, offline-first mobile systems, and large-scale event workflows. Your vision of an anti-scalper ticketing system by design—with non-transferable tickets, late reveal, rotating QR tokens, waitlist reissue, and offline scanning is exactly the type of system we build: reliability first, abuse-resistant, and smooth for real users under real venue conditions. We will provide building a full ecosystem: - Consumer iOS + Android app - Admin / venue web portal - Gate staff scanner app - Backend APIs, auth, payments, deployment With core principles: - No peer-to-peer transfers - Tickets locked until close to doors - Rotating QR tokens that can’t be screenshotted - Return-to-platform with waitlist reissue - Offline scanning with conflict resolution - Venue dashboards, audit logs, and risk tooling I am available online for the interview else we could fix a meeting and discuss the project in detail. I am Sincerely looking forward to communicate with you as a person and I would really appreciate if you give us your valuable time. Regards Ana

Hi. As an Ionic Expert, I am very interested in your project. I am very familiar with Ionic, Angular and C#. I have mobile and backend skills with 8+ years. I wish to work for you. Thanks for attention.

@asifalimzd

Hi, I’m a senior Ionic/Angular developer with 5+ years of production experience building and maintaining complex mobile apps backed by C# Web APIs. I’ve worked on CRM systems, field-service apps (offline-first, job dispatch, real-time sync), and inventory/stock control modules, so I’m very familiar with the exact kind of architecture and challenges you’re describing. I can help you: Stabilise and refactor existing Angular + Ionic code Improve offline sync and data consistency Optimise and extend your C# Web API Fix performance and reliability issues across CRM, field-service, and stock modules Implement clean, maintainable patterns for future scaling I’m comfortable jumping into existing codebases, identifying technical debt, and making pragmatic improvements without breaking live systems. I can start immediately and work hands-on with your repo and API to assess bottlenecks and propose a clear improvement plan. Happy to share relevant apps/repos and walk you through similar systems I’ve delivered.

Hi - I d come in as the “seasoned hand” to stabilise the Ionic + Angular app and make the C# Web API predictable. First I d do a quick audit -> current crash points, API contracts, auth, and the offline sync layer so we know what is breaking and why. Then I d harden the core flows in order: CRM (records, leads, deals, quotes, activities), field-service (dispatch, on-site updates, offline mode), then stock control (inventory accuracy, barcode scan, reorder triggers). On the API side I d tighten endpoints, validation, paging, and error responses so the mobile app is not guessing about state. For offline sync I d implement clear conflict rules, idempotent writes, and retry logic so a tech can work without signal and still sync cleanly later. I ll keep changes small and shippable, with a short weekly note: what changed, what got faster or more stable, and what is next. If this direction aligns, we can discuss in detail in chat.

@Herculesz

Hi I can stabilize and expand your Angular + Ionic mobile app by addressing core issues across CRM, field-service workflows, and real-time stock control. The main challenge is ensuring smooth communication between the Ionic front end and your C# Web API, which I handle through clean service layers, optimized endpoints, and robust offline-sync logic. I bring production-level experience improving complex modules involving leads, quotes, dispatch flows, and inventory scanning. I will refine UI components, streamline data handling, and eliminate reliability gaps in API interactions. Advanced caching, error handling, and background-sync patterns will strengthen app performance in the field. I can share proven repos and examples of apps integrating Angular, Ionic, and C# back ends. Thanks, Hercules
