Project Overview ● Project Name: Aorbo Treks Portal & Mobile Application ● Client / Intellectual Property Owner: AORBO INFOCOM ● Registered Address: Flat 205, MS Arcade, New Market, Malakpet, Hyderabad, Telangana, India. ● Objective: Technical assistance for comprehensive flow testing, bug fixing, critical API integration, financial logic stabilization, and setting up an automated server hosting environment. Scope of Work A. Admin Portal Flow (Web) ● Overall Control Testing: Testing the master dashboard for total user management, system settings, and analytics. ● Approval Framework: Verifying the approval panel where admin reviews and approves/rejects trek listings submitted by vendors. ● Financial Oversight: Auditing the panel for settlement reports, platform fees tracking, and manual/automated refund triggers. B. Vendor Portal Flow (Web) ● Onboarding & KYC: Testing the vendor onboarding flow, document uploads, and profile verification status. ● Trek Management: Verifying the complete lifecycle of creating, editing, updating pricing, adding itineraries, and deleting a trek listing before it goes to Admin for approval. ● Booking & Inventory Management: Testing how vendors see incoming bookings, manage slots capacity, and view their balance/payout logs. C. Mobile Application Testing & Bug Fixing The selected vendor/developer will review the existing Flutter mobile application (Android & iOS) to identify and address system issues. Bug resolution will be split into two categorie ● Major Bugs (Vendor Responsibility): The vendor must identify, trace, and completely fix all critical bugs impacting core user flows. ● Minor Bugs (Client Information): The vendor is required to log and document minor cosmetic or UI issues and share them with our in-house team for internal resolution. 2. Core API Integrations & Financial Logic A. 2-Factor SMS Gateway API ● Authentication Security: Seamless integration of the SMS gateway for secure user registration, login via OTP, and protection against authentication fraud. ● Transaction Alerts: Automate triggered SMS notifications immediately upon successful booking or transaction status changes. ● Procurement Assistance: The vendor must assist in selecting, purchasing, and configuring the most reliable and cost-effective SMS gateway provider. B. Razorpay Payment Gateway Integration ● Complete Payment Workflow: End-to-end integration handling the complete checkout flow, payment cycles, transaction verification, and webhooks. ● Refund System: Implementation of backend business logic to handle partial and full refunds seamlessly via the Razorpay API based on cancellation policies. ● Security & Data Integrity: Ensuring idempotent transactions (preventing double-charging) and server-side verification of payment signatures to maintain accurate financial ledgers. 3. Business Logic Corrections & Stabilization ● Review and audit the existing application architecture (Flutter frontend connected to Node.js / MySQL backend). ● Identify and correct gaps in data validation, session management, or booking logic to achieve a production-ready, highly stable product. 4. Server Hosting & CI/CD Implementation ● Server Deployment: Configure and host the production-ready Node.js backend and MySQL database on a secure, scalable cloud server. ● Process Management: Implement a process manager (e.g., PM2) to ensure high availability, automatic crash restarts, and zero-downtime performance. ● Jenkins Automation: Set up a clean CI/CD (Continuous Integration / Continuous Deployment) pipeline using Jenkins on the server to automate code pulling, building, and deployment for future updates. Deliverables Expected from the Vendor 1. Complete source code with major bug fixes applied and verified. 2. Fully functioning payment and SMS gateway workflows on live staging/production environments. 3. Automated deployment setup running seamlessly via Jenkins. 4. A brief technical hand-off document outlining the server details and API configurations.

Hi there, I have read your project requirements and understand that you need technical assistance for the Aorbo Treks platform, including end-to-end flow testing, major bug fixing, API integrations, financial logic stabilization, and production server setup with CI/CD automation. The goal is to deliver a secure, stable, and production-ready ecosystem across the Admin Portal, Vendor Portal, Flutter mobile applications, and Node.js/MySQL backend. We have experience working with Flutter applications, Node.js backends, payment gateways, OTP authentication systems, cloud deployments, and CI/CD pipelines, ensuring reliable and scalable solutions. A few questions before proceeding: ============================= Is the current application already deployed on a cloud server, or does the production infrastructure need to be configured from scratch? Approximately how many major bugs or known issues have already been identified? Do you have a preferred cloud provider for hosting and Jenkins deployment? Which SMS gateway providers are you currently considering, or would you like us to recommend the most cost-effective option? Best Regards, Srashtasoft Team

Your Aorbo trek portal needs Node.js backend fixes, Razorpay integration, and Flutter app bug resolution — exactly the kind of production stabilization we've done before. We've built similar booking + payment platforms (travel and appointment scheduling verticals) with Razorpay webhooks, OTP SMS gateways, and CI/CD on cloud servers. Our team covers the full stack: Node.js/MySQL backend, Flutter mobile, and Jenkins deployment pipelines on GCP. I'd start with a thorough codebase audit to document all bugs, then tackle Razorpay refund flows and SMS OTP integration in parallel. CI/CD with PM2 + Jenkins follows for a clean production handoff. Ping me and we can align on milestones and a realistic timeline.

Hi, I can help with the backend/API stabilization side of this project, especially Node.js/MySQL flow testing, Razorpay payment verification, SMS/OTP integration, booking logic, and deployment hardening. Because the scope is broad, I would start with a focused technical pass instead of promising everything at once: - review the current Node.js/MySQL API flow and identify blocking bugs - verify Razorpay order/payment/webhook/refund handling and signature checks - check OTP/SMS integration points and transaction notification triggers - review booking, inventory, settlement, and refund logic for data consistency - prepare a short fix list with priority, then implement the highest-impact backend/API fixes first - help stabilize PM2/server deployment and CI/CD steps once the application flow is confirmed I work carefully with production-style backend systems, APIs, database logic, and deployment debugging. I will keep communication clear, document what is changed, and avoid touching unrelated mobile/UI code unless it is needed to trace a backend issue. A few questions before starting: 1. Is the Node.js/MySQL backend already deployed somewhere, or only running locally? 2. Are Razorpay and SMS gateway credentials already available in test mode? 3. Should the first milestone focus on payment flow, OTP/login, or booking/vendor/admin bugs?

That's exactly where we spend most of our time, making sure everything feels clean, intuitive, fast, and built for long term growth. We handle the entire process from planning and design through development, automation, integrations, testing, and ongoing support. A quick question. If we spoke now and this project was considered a complete success, what would need to happen for you to feel it was one of the best investments you've made? I'd love to chat about your project! The worst that can happen is you walk away with a free consultation! Regards, Ryan.
