Good day!
My name is Ruslan, I am a backend/fullstack developer with commercial experience in Node.js, NestJS, React, MongoDB, as well as practical experience working with complex WebView applications and publishing applications on Google Play and the App Store.
In my recent projects, I have worked on systems that are very similar to your stack and functionality:
🟦 My relevant experience:
• Chats — custom implementation of chat modules: messages, attachments, editing/deleting, creating dialogues and groups.
• Video calls — integration of WebRTC through third-party services and custom signaling servers.
• Admin panels — building secure admin panels with JWT, roles, access rights, statistics, and content management.
• File sharing — implementation of upload, CDN, resizing, access via link.
• Payments and subscriptions — I have done integrations with WayForPay (creating payments, webhooks, confirmations, recurring charges).
• Calendars, bookings, schedules — experience in building complex calendar modules (reservations, time slots, recurring events).
• WebView (iOS/Android) — I work with mobile WebView applications, Push notifications, and internal APIs.
• Application publishing
▫️ Google Play — preparing bundle, signing, creating releases
▫️ App Store — certificates, provisioning profiles, TestFlight, App Store Connect
🟩 What I can offer:
• Ongoing project support
• Development of functionality and optimization
• Quick response to tasks
• Secure and scalable architecture
• Communication every day (if needed)
I would be happy to discuss the details, review the project, and understand the scope of work.
I can start immediately.

Hello.
I can support your WebView application on a long-term basis, maintaining and improving the Node.js backend and React frontend, ensuring the stability of all core features: calendar, video calls, admin panel, chats, file sharing, and subscription payments through WayForPay. I will systematically review the current architecture, optimize weak points, and implement clean, scalable solutions where necessary. With experience in publishing and maintaining applications in both Google Play and the App Store, I can also handle updates, fixes, and compliance requirements for seamless releases. My goal is to provide reliable ongoing support, quick response to issues, and continuous improvement to ensure your product operates efficiently.
