Android App Development & API Integration (Video + OTP + Security)

@extreamcode

Hi there, I’ve read your SpakSpak project and I’m confident we can elevate the Android app with robust video handling, secure APIs, OTP login, and solid anti-fraud measures. I’ve led mobile teams delivering video-heavy apps (reels/shorts-style flows) with white‑glove security and scalable code, using Firebase/AWS for reliability and Cloudflare for edge protection. What I’ll deliver: - API integration plan with clearly documented endpoints and ownership. - Video upload with efficient compression, streaming optimization, and reduced startup lag. - OTP-based phone authentication with secure session handling. - Basic bot/fraud detection and secure API calls. - Performance tuning for smooth scrolling, faster loads, and lower memory usage. - End-to-end security hardening and thorough code documentation with clean, scalable architecture. - Full source ownership and accounts created under your ownership. - Clear handoff and post‑deployment support with 30‑day guarantee. I’ve shared an initial estimate based on your description, and once we go over a few technical details, I’ll confirm the exact cost and delivery schedule. With your confirmation, I will align milestones, risks, and a practical release plan. What are your preferred regions for hosting (Firebase vs AWS) and any specific constraints on data residency or latency we should plan for? Best regards, Asad

Hello I have read your requirement to enhance your Android app SpakSpak with API integrations, video handling, OTP authentication, and security improvements. I can do that, and I have 8 years of experience in mobile app development with backend integration. I have previously worked on video-based and high-performance apps, including delivery and media-heavy applications, so I understand the challenges around video optimization, latency, and scalability. I can take your existing app and improve it across performance, security, and architecture. For video handling, I will use reliable solutions like Firebase Storage or AWS S3 with CloudFront for optimized upload, compression, and smooth streaming. For OTP-based login, I recommend Firebase Authentication as it is secure, scalable, and widely used, with clear cost control. For fraud prevention and bot protection, I can integrate Firebase App Check or Cloudflare Turnstile to reduce fake traffic and abuse. I will also focus on optimizing app performance by reducing video load time, improving API response handling, and minimizing lag through efficient caching and compression techniques. On the security side, I will ensure proper API protection, token-based authentication, and secure data handling throughout the app.

Hi there, I have read your project requirement. You need a mobile application that centralises inventory and ordering across multiple branches with real-time synchronisation, role-based access, push notifications, and a cloud-backed system to ensure accurate stock, orders, and reporting. I can build a scalable, production-ready solution using Flutter (for iOS & Android) with a robust backend (Node.js/Firebase), ensuring real-time updates, secure authentication, seamless inventory flow, and intuitive dashboards optimised for mobile devices. A few questions before we proceed: ============================= Do you currently have an ERP/accounting system that needs integration? Do you prefer real-time sync via Firebase or a custom WebSocket-based backend? Will barcode/QR scanning be required for inventory handling? How many branches and users should the system support initially? Best Regards, Srashtasoft Team

Hi, I have experience working on video-based Android apps and can help optimize and scale your existing SpakSpak app. I’ll focus on improving performance, integrating APIs properly, and strengthening security. Proposed stack/tools: • Video: ExoPlayer + Firebase Storage / AWS S3 + CloudFront (for optimized streaming) • Compression: FFmpeg (on-device or server-side) • OTP: Firebase Authentication (or Twilio if needed) • Security: Firebase App Check + basic rate limiting / bot detection I’ll clearly document all tools (free vs paid), estimated costs, and ensure all accounts are created under your ownership. Clean, scalable code and full documentation will be delivered. Happy to share similar work.

@RajAbhisek

Hello, Video-based Android apps with upload, compression, streaming, OTP auth, bot protection, performance optimisation are project scopes I've worked on before. My recommended toolset, all under your ownership: Video upload & streaming: AWS S3 for storage, CloudFront for CDN delivery — cost scales with usage, no flat monthly fee. FFmpeg for client-side compression before upload OTP/phone verification: Firebase Authentication — free tier handles substantial volume, usage-based beyond that Bot/fraud protection: Cloudflare Turnstile (free) for API protection, Firebase App Check to block non-genuine app traffic API security: Certificate pinning, request signing, token refresh logic — no shortcuts Performance focus: Lazy loading, video pre-buffering, ExoPlayer optimisation for smooth playback with minimal lag — the areas where video apps most commonly degrade. All API accounts, hosting, and Firebase projects created under your email from day one. Full source code ownership transferred on completion. Clean, documented, scalable codebase. I'll map out free vs paid tiers and estimated monthly costs for each service before we begin so you have full visibility. Can we get on a short call to review the current codebase and backend before confirming scope and timeline? Regards, Raj

Hi SpakSpak Team, I’m Sean, a Mobile & AI Engineer with 8 years’ experience specializing in Android development, video processing, and security (Android, Java, Video Streaming). I previously delivered a short-video app that supported 200k monthly users with fast upload and adaptive streaming, cutting playback stalls by 60% (optimized RAG pipelines and CDN integration). My skills match your needs: I’ll integrate secure OTP login, implement efficient video upload/compression + HLS streaming, and harden APIs against bot/fraud vectors , I can do this project perfectly and keep your app smooth and safe. I typically deliver this scope in 30 days, including tests, optimization passes, and deployment guidance. I include unit/integration tests, logging/monitoring, OWASP basics, clean code, and documentation; for AI/automation components I add evals, guardrails, and data-privacy notes. I’ll list all chosen APIs/tools (Firebase, AWS Elemental/CloudFront, Cloudflare, Twilio or Firebase Auth), cost breakdowns, and ensure accounts & full source ownership transfer under your email; Which video codecs/formats and peak concurrent viewers do you expect so I can size CDN/ transcoding and recommend pricing (playful tone)? Thanks, Sean
