As an experienced software engineer with a focus on .NET and website design, I'm confident that I can exceed your expectations for your multi-module travel portal. My thorough understanding of the .NET framework would allow me to build each module flow (Search -> Listing -> Detail -> Add-On -> Contact -> Payment -> Confirmation) in your app seamlessly. I've also mastered API development, a core component of your project, and can ensure that secured mock API calls are made for all required services. Moreover, my expertise extends to payment gateway integration, SMS registration and email notification systems you mentioned. These are vital components that require a commitment to both security and reliability - elements I prioritize fervently in my work. Additionally, since phase one involves saving data on Google Sheets rather than SQL server, my familiarity with Google Sheets' APIs will help streamline this process. Your project requires a skilled communicator who can deliver under tight deadlines - which is precisely what you'll get from me. I foster transparent communication throughout the development process, providing regular updates and comprehensive QA reports at every milestone delivery. This way, you have a clear view of the progress being made.

Hello, I understand you want to build a travel booking portal (Onetravel-style UX) using .NET + Bootstrap, starting with a fully working Flight booking module and scalable structure for future expansions. I can deliver a clean, responsive, and modular system while keeping development cost-efficient using reusable components/templates. Proposed Approach: • Backend: ASP.NET Core (secure API layer) • Frontend: Bootstrap (responsive, Onetravel-like UX) • Data: Google Sheets integration (phase 1, no SQL) • Integrations: Payment gateway + Email/SMS notifications Flight Module Includes: • Search → Listing → Details → Add-ons → Contact → Payment → Confirmation • Email confirmation + data logging in Google Sheets Admin Panel: • Manage markup & service fees • Theme customization • Manage packages (Flights, Hotels, Cars, etc.) Deliverables: • Fully working .NET solution (Flight module first) • Responsive UI matching required UX flow • Admin panel + complete source code • Setup guide + demo I’ll focus on fast delivery for the first milestone so you can validate and scale further. Feel free to message me so we can discuss the project further. Warm regards, SamreenCoders

Hi, This is a good fit for me because the project already has a clear first target: **get the Flight flow working end-to-end first**, then expand into Hotel, Car, Bus, Holiday packages, and Android. That is the right way to build this on a tight budget without creating a messy system. I can help you build the **.NET + Bootstrap** portal with the full flight journey: **Search → Listing → Detail → Add-On → Contact → Payment → Confirmation**, plus email notification, mock secured APIs, Google Sheets storage, and an admin panel for markup, fees, theme controls, and future module management. What stood out to me is that you want something close to **Onetravel’s UX** while still keeping the code fully editable and extendable later. I’d approach this by reusing a strong Bootstrap structure, keeping the backend modular, and making sure phase one looks polished enough for demo while staying ready for the next modules. I’m also fine with a **phase-based approach** so you get a working flight demo first and don’t overspend too early. If you want, send me your expected first milestone scope, and I’ll tell you the cleanest build path right away. Best regards. Ankit.

Let me get it done, I'll build your travel portal using ASP.NET Core and Bootstrap to replicate the Onetravel UX while ensuring a fully responsive design and a modular architecture that allows for easy expansion into hotels and cars. Your project will be finished in 3 weeks, I have built similar websites before when working for web development agencies. Here is how I would approach it: 1. I can do a free demo if needed. We will plan everything out together, go through all the requirements, and then start. 2. I will set up the core .NET backend with a secure mock API layer to handle the flight booking flow from search to confirmation. 3. I will integrate the Bootstrap frontend to mirror the Onetravel UX, ensuring all UI modules communicate correctly with the backend. 4. I will implement the Google Sheets integration as the primary data storage for transactions and the email/SMS notification service. 5. I will build the admin panel to manage markups, themes, and content, providing you with full, clean source code for your future expansion. Let's talk as soon as possible and get it done. Best Regards, Mihajlo

@bartuonler

Hello, Your project is a production-level AI chatbot system focused on sales conversion, not just a simple integration. I have experience building chatbot and backend systems with NLP, API integration, and product recommendation logic. My approach: Backend & NLP: I will set up a production-ready backend using Python (FastAPI) or .NET Core depending on your stack. NLP will be integrated using OpenAI API or a RAG-based system for intent detection and dynamic responses. Product Recommendation: The chatbot will connect to your product catalog via API or database and suggest relevant products in real time based on user behavior and conversation flow. Widget / API: A lightweight JavaScript widget will be provided to embed on any page with a single script. Secure API communication will handle all interactions. VPS Setup: Your VPS will be configured for production use including deployment, environment setup, and security. Documentation: You will receive clear documentation for updates, prompts, and system management. I can also review your current setup and provide a quick architecture plan before starting.

@bilal0225

Hello, I understand you need a .NET-based travel portal with a complete flight booking flow similar to OneTravel. I can build a clean, responsive solution using ASP.NET and Bootstrap, including search, listing, details, add-ons, contact, payment (sandbox), and confirmation, with data stored in Google Sheets. I will also create a secure API layer, basic admin panel, and provide a fully working demo (video or live). The code will be well-structured, reusable, and easy to extend. I have hands-on experience with C#, ASP.NET, APIs, and frontend development, and I can deliver a reliable MVP within your budget. I’m also open to long-term collaboration for future phases. Let’s discuss your timeline and any specific design preferences.

Hi there, The best solution is to build your portal in .NET Core + Bootstrap with a modular structure so the Flight flow is completed first, then Hotel, Car, Bus, Holiday Packages, and the Android app can be added smoothly without rebuilding the system. I would use reusable components for Search, Listing, Detail, Add-On, Contact, Payment, and Confirmation, plus a secure mock API layer and Google Sheets integration for phase one. My step-by-step approach: -Build the full Flight booking flow end to end -Connect payment, SMS, email notification, and Google Sheets read/write -Create the admin panel for markup, fees, theme settings, and package management -Match the UI/UX closely to Onetravel’s responsive design language using Bootstrap - Deliver clean source code, setup guide, and a working demo I have 8+ years of experience in .NET, C#, Bootstrap, API integration, admin panels, and scalable web applications. I can keep the code clean, editable, and structured for long-term expansion while staying practical with your current budget. I understand you need a developer who can help you start lean and grow the project in phases. I can do that and would be glad to support future modules after the Flight MVP is complete. Best regards, Oluwatobi Okedairo

Hi, I can deliver this project quickly because I already have 60% of the flight booking system completed in .NET with Bootstrap, following the same Search → Listing → Detail → Add-On → Contact → Payment → Confirmation flow similar to OneTravel. My existing build already includes: • Responsive Bootstrap UI matching modern OTA UX • Flight search + listing structure (mock API ready) • Flight detail page layout • Add-on services framework (bags, seats, meals) • Contact traveler form • Payment flow structure with gateway integration ready • Confirmation page template with email trigger • Google Sheets integration for saving booking data (no SQL) • Secured mock API layer in .NET What I will complete for your demo: • Full end-to-end Flight booking flow • Google Sheets read/write for all transactions • Email notification + SMS registration • Admin panel (markup, service fees, theme controls) • Editable source code with clean architecture • Live demo or recorded walkthrough Tech stack: ASP.NET (.NET Core), Bootstrap responsive UI, REST mock APIs, Google Sheets API, Payment Gateway integration, Email & SMS notifier. Since much of the system is already built, I can deliver faster and within your tight budget. After the flight module, I can extend the same architecture to Hotels, Cars, Bus, Holidays and Android app. I can share screenshots/demo of the current progress. Let’s connect and I’ll show what’s already working.

@Viku29

Hi, I carefully read your project and I understand that you want to build a travel portal starting with the flight booking module. Instead of building everything at once, I suggest starting with a clean and working flight module (Search → Details → Add-ons → Contact → Payment → Confirmation) as your first phase. I have experience in ASP.NET Core, Web API, and building structured applications. I can help you: ✔ Develop the complete flight booking flow ✔ Build responsive UI using Bootstrap ✔ Create secure API structure ✔ Handle payment and email confirmation ✔ Build a simple admin panel I also like your approach of starting simple (Google Sheets instead of SQL) – we can design it in a scalable way for future upgrades. Can you share if you already have any flight API or should we use a demo/mock API? Looking forward to working with you. Thanks Please ph no 77.77 . 01.7. 07.7. . Vikram from Hissar
