Tax Audit Mobile App Development -- 2

@Srashtasoft

Hi Dear, We can build this using Flutter for a high-performance single codebase, integrated with your backend APIs, Stripe SDK for secure payments, real-time tracking (Google Maps), push notifications, and offline handling. The app will be optimised for smooth UX, secure data handling, and full compliance with App Store and Google Play guidelines. A few questions to proceed: ======================= Are your backend APIs fully ready or still under development? Do you already have real-time tracking APIs (driver location updates)? Any preferred payment gateway other than Stripe? What is your expected timeline for MVP launch? Best Regards, Srashtasoft Team

I can build this using Flutter (single codebase for iOS & Android) + Node.js (NestJS) backend + PostgreSQL + secure cloud storage (AWS S3/GCP). OTP authentication can be handled via trusted providers (Firebase/MSG91), and all APIs will be secured using JWT with proper token lifecycle management. PDFs will be streamed securely (not exposed publicly), with controlled download and no sensitive caching. The system will include a clean mobile app (PAN/mobile OTP login, dashboard, year-wise data, in-app PDF viewer) and a web-based admin panel for full control over users and document uploads. Everything will be structured for fast access, encryption in transit, and safe storage. To align perfectly: Do you already have existing data (PDFs/users) to migrate? Which OTP provider do you prefer (Firebase, MSG91, or others)? Any compliance requirements (CA-specific, audit logs, etc.)? Looking forward to hearing back from you and discussing this in the chat.

Hi! I’ve reviewed your project for the Tax Audit Mobile App and am confident I can deliver a secure, high-performance Flutter solution. My approach focuses on building a "security-first" architecture that handles sensitive financial data with encrypted storage and seamless offline-to-online synchronization—essential for auditors working in the field. I specialize in creating intuitive, high-validation forms and instant PDF report generation, ensuring that the transition from manual audits to your digital platform is both efficient and error-free. I’d love to discuss your specific workflow requirements and show you how we can streamline your audit process. -Shailender

Hi — this is a great use case, and the key here is not just building an app, but handling **sensitive financial data with speed + security + simplicity**. From your brief, the experience must feel instant and trustworthy, especially around login (OTP), document access, and multi-year data handling. I’d approach this with a clean, scalable setup: **Tech Stack Proposal** * **Flutter** (single codebase, near-native performance) * **Backend:** Node.js (secure REST APIs + JWT auth) * **Database:** PostgreSQL (structured financial records) * **Storage:** AWS S3 (private buckets, signed URLs for PDFs) * **OTP:** Firebase Auth or MSG91 (reliable in India) * **Admin Panel:** React (fast CRUD dashboard) **How I’ll build it:** * Secure OTP login (PAN/mobile) with token-based session handling * Fast dashboard with year-wise data (3–10 years, optimized queries) * In-app PDF viewer + secure download (no public exposure) * Strict security: encrypted APIs, no sensitive caching, protected logs * Admin panel with full control (users, uploads, deletions) * Weekly builds (APK/TestFlight) for progress tracking **Estimated timeline:** 35–50 days (with weekly milestones) **Budget:** Can vary based on final scope (OTP provider, infra, scaling needs), but I can share a precise breakdown after a quick discussion. If you’d like, I can first map the app flow + database schema so we lock everything before development starts. Let’s build something secure, fast, and client-friendly ?

I can deliver this secure finance app based on my recent Audit App project, where I built OTP login, encrypted document access, and financial dashboards. I propose Flutter for a single Android & iOS codebase with native-like performance. Users will log in via PAN/mobile OTP (Firebase Auth/Twilio), access a clean dashboard, view year-wise financial data, and open/download PDFs securely within the app. No sensitive data will be cached, and all sessions will be protected using JWT authentication. Backend will be Node.js (Express) with PostgreSQL for reliable and scalable data management. File storage via AWS S3 or Firebase Storage using secure, environment-based access and signed URLs. Admin panel will be built in React.js with full CRUD: manage users, upload/delete PDFs, and control all app data. Deliverables: complete source code, deployed backend, database schema, APK & TestFlight builds, plus documentation and demo. Estimated timeline: 40–45 days with weekly updates and test builds.
