The Problem
A client running a hotel/travel booking system had bugs affecting the reservation flow — the part of the system where guests search an existing reservation ID, confirm check-in/check-out dates and party size, and enter full guest details (name, contact info, passport number and expiry) to complete a booking. Issues in that flow put real reservations at risk of failing or saving incorrect data.
The Solution
I diagnosed and fixed the reservation-flow bugs directly in the existing ASP.NET/SQL Server codebase, working within the client's established system rather than rebuilding it. The fix covered the reservation search, the booking information step (check-in, check-out, adults), and the guest details form (name, address, contact info, and passport details for multi-guest bookings), ensuring each step correctly validated and saved data before a booking could be created.
Key Features
Reservation lookup — search and load an existing reservation by ID.
Booking details validation — check-in/check-out dates and guest count entered correctly and validated before proceeding.
Multi-guest details capture — full guest information (name, address, country, email, phone, date of birth, passport number and expiry) captured per guest for bookings with more than one traveler.
Reliable booking creation — the final "Create Booking" step correctly commits the reservation once all prior steps validate.
Technical Highlights
Fixes were made directly against the client's existing ASP.NET and SQL Server codebase, requiring careful diagnosis of the existing reservation and guest-details logic before changing it — the kind of work that depends on understanding someone else's codebase quickly and fixing root causes rather than symptoms, since the system was already live and in use.

HIGHLY RECOMMEND him for any software development needs!"
FAQ
What kind of bugs were actually being fixed in this booking system?
Issues in the reservation flow — searching an existing reservation by ID, confirming booking details like check-in/check-out and guest count, and capturing full guest details for multi-guest bookings — that could cause a reservation to fail or save incorrect data.
Was this a full system rebuild or a fix to an existing system?
A fix to an existing, already-live ASP.NET/SQL Server booking system — the work involved diagnosing bugs in code that was already in production, not building a new system from scratch.
How long did this engagement take?
1–7 days, delivered directly through Fiverr with a fixed price range of $50–$100 for the scope of work.
Does the fix support bookings with multiple guests?
Yes — the guest details step was fixed to correctly capture and save full information (name, contact details, passport number and expiry) for each guest on a multi-person reservation.
Is there a client reference for this work?
Yes — a verified 5-star review on Fiverr: "Yasir Rehman truly exceeded my expectations! His professionalism and code expertise stood out, and working with him was a breeze thanks to his prompt delivery and responsive communication."
