I already have an Android Device Policy Controller that locks financed handsets when an EMI is missed, plus a small web dashboard that lets the lending team provision devices and trigger unlocks. The current build is unstable on Android 13, the UI feels dated, and the payment workflow is tied to a gateway we no longer use. I need the entire solution rebuilt and hardened. Core behaviours that must work flawlessly: • Lock the phone the moment a scheduled payment fails. • Allow me to whitelist only basic apps (dialer, messages, payment app) while the device is locked. • Push automatic reminders before the due date and after a failure until settlement. • Capture an e-mandate (eNACH/UPI AutoPay) during onboarding so future EMIs run without user action. The admin portal should let me create a customer record, push the DPC during device setup (QR or NFC provisioning), set or edit the repayment calendar, view real-time compliance status, and manually override a lock if support approves. Please keep the API layer clean so I can later plug in analytics. Tech stack is flexible, but you must already be comfortable with Device Owner APIs, foreground services, FCM, WorkManager, and a modern payment gateway that supports e-mandate (Razorpay or Cashfree preferred). The existing code is in Kotlin and React; reuse whatever speeds you up, but I’m fine if a fresh codebase gets us a smoother outcome. Acceptance will be: 1. APK installs as Device Owner on Android 8–13, passes all scenarios above, and survives reboots, factory resets blocked. 2. Portal deploys on my AWS instance with SSL, role-based access, and logs every policy action. 3. Clear, buildable source plus setup notes so my in-house dev can extend it later. If you’ve shipped DPCs or MDM features before, tell me what provisioning method you’d choose first and how long you’ll need for a pilot build.

Your DPC will fail compliance audits if the e-mandate capture happens after device provisioning instead of during onboarding, because users can skip payment setup and you lose enforcement leverage before the first EMI is even due. Factory-reset protection also needs to be tied to your backend whitelist, or a determined user will wipe the policy by forcing Safe Mode during boot. Quick questions - are you planning to enforce geofencing or SIM-lock rules if a device goes offline for more than 72 hours? And does your lending agreement allow you to remotely wipe user data after 90 days of non-payment, or only lock access? Here is the architectural approach: - DEVICE OWNER API: Provision via QR code with zero-touch enrollment so the DPC becomes irremovable, then use DevicePolicyManager to whitelist only dialer/SMS/payment apps and block uninstall attempts even in Safe Mode. - E-MANDATE INTEGRATION: Capture Razorpay eNACH tokens during first unlock, store encrypted mandate IDs server-side, then trigger auto-debit via cron 48 hours before due date so you catch failures early enough to send reminders before the actual lock event. - REAL-TIME SYNC: Use FCM for instant lock commands and WorkManager for offline retry logic, with a fallback polling layer every 6 hours in case push fails, so compliance state stays accurate even when the device has intermittent connectivity. I've built two similar DPC solutions for BNPL providers in India that handled 12K+ devices under active management without a single provisioning failure. Let's schedule a 20-minute call to walk through your AWS setup and confirm the exact provisioning flow before I start the pilot build.

Hi, I can rebuild your EMI Locking DPC and admin portal so lock, whitelist, reminders, and eNACH/UPI AutoPay work cleanly on Android 8 to 13, with QR and NFC provisioning, real-time compliance status, and manual override. I will keep Razorpay or Cashfree behind a clean API layer for later analytics. For the Device Owner side, I will use foreground services with WorkManager and FCM so locks survive reboots and factory reset stays blocked. Questions: 1) Do you prefer QR or NFC as the primary provisioning path for the pilot? 2) Razorpay or Cashfree for the e-mandate? Looking forward to discussing further. Regards, Shayan.

Hi, I can rebuild and harden your existing Android DPC + lending portal with a focus on Android 8–13 stability, reliable device-policy enforcement and a clean API architecture. I understand the critical requirements around: Device Owner provisioning via QR/NFC EMI-based lock/unlock policy Restricted app whitelist while locked FCM + WorkManager reminders Reliable behaviour across reboots/offline scenarios eNACH/UPI AutoPay integration using Razorpay or Cashfree React admin portal with RBAC and complete policy-action logging AWS deployment with SSL and clean API separation For provisioning, I would start with QR-based Device Owner provisioning because it provides a straightforward, repeatable pilot workflow; NFC can then be added where the hardware/setup requires it. I would first audit the existing Kotlin DPC and payment flow, identify the Android 13 stability issues, then build the pilot around the critical lock, whitelist, reminder and mandate scenarios before expanding the portal. I’ll provide buildable source code, deployment/setup documentation and a clean API structure suitable for future analytics integration. Best regards, Vinod

You need a production-ready Laravel deployment on AWS EC2, with the existing application kept intact while the server, database, domain, SSL, and runtime environment are configured correctly. I’m Swapnil Karma, Founder & CEO of NetSwap Technologies, leading a 10–20 engineer team experienced in Laravel/PHP, MySQL, AWS, Linux deployments, and production troubleshooting. I’ll handle the deployment end-to-end: Audit Laravel/PHP and server requirements Configure EC2, PHP, Composer and required extensions Deploy the code and securely configure .env Connect MySQL and run required migrations Configure Nginx and point the domain to Laravel’s public directory Set permissions, storage links, caching and production settings Configure SSL/HTTPS and security groups Test routes, assets, authentication and database operations Resolve any deployment/runtime issues before handover Provide a clear deployment log and replication notes I’ll avoid unnecessary code changes—the goal is a stable production deployment of your existing application. Estimated timeline: 1–2 days, assuming the codebase and credentials are ready. I suggest milestones around EC2 setup → application/database deployment → domain/SSL → complete testing & handover. To confirm the exact configuration, please share the Laravel/PHP version and whether your MySQL database is already hosted on AWS or externally.
