Job Title: Software Developer Required – Parking System API Integration for Pay-on-Foot Machine Project Description: We are looking for an experienced software developer to support integration between an existing Pay-on-Foot parking payment machine and a “Find My Car” system. The Pay-on-Foot machine is currently operating on a Windows 10 PC, connected to the parking network and linked with an SQL database. The machine has a touchscreen interface. Required Scope of Work: The developer will be required to create or modify the software interface so that the Pay-on-Foot machine can: 1. Send an API request to the “Find My Car” system. 2. Retrieve the car parking location details. 3. Retrieve and display the vehicle image on the touchscreen. 4. Retrieve or calculate the parking fee amount. 5. Display the parking charge clearly on the screen. 6. Allow the customer to press a “Pay” button. 7. Once the customer presses “Pay,” the existing payment system will continue the remaining payment process. Developer Requirements: The freelancer should have experience with: * Windows desktop application development * API integration * SQL database connection and queries * Touchscreen user interface design * Parking management systems or payment systems preferred * C#, .NET, Python, or similar suitable technologies * Ability to work with existing software and hardware environment Expected Deliverables: * Working software/module integrated with the Pay-on-Foot machine * API request and response handling * Display of car location, image, and parking charge * Touchscreen-friendly interface * Testing on site or remotely with our technical team * Basic documentation for installation and operation Important Note: The payment processing itself is not part of this scope. The developer only needs to prepare the screen and logic up to the point where the customer presses the “Pay” button. The existing parking/payment system will handle the remaining payment steps. Please include in your offer: * Similar experience * Proposed technology * Estimated delivery time * Total cost * Support period after delivery * Any requirements needed from our side, such as API documentation, SQL access, or remote access to the machine.

Hello, I understand you need a Windows desktop module that connects the Pay-on-Foot machine with your Find My Car system. I will build a compact, reliable interface that sends API requests, retrieves location details and vehicle image, computes or fetches the parking fee, and displays it clearly on the touchscreen. The solution will expose a “Pay” action that hands off to your existing payment flow, while handling API calls, SQL data access, and a touch-friendly UI tailored for your machine. My approach is to implement a lightweight .NET/C# component that integrates with your SQL database and the Find My Car API, with robust error handling, logging, and secure data transfer. I’ll deliver a tested module that can be deployed on the Windows 10 PC, with on-site or remote validation alongside your technical team and concise installation/operation docs. I’ll ensure the UI stays clean on a touchscreen and works with your current hardware and network setup. Do you have API documentation and access credentials ready for integration? Best regards,

Hi, This is Elias from Miami. I have checked your project description and understand that you're looking to integrate an API for a pay-on-foot parking machine system. This will likely involve managing transactions and user interactions efficiently. I have experience in API development and backend integration, having worked on similar projects where I built secure and robust solutions for payment systems. To approach this project, I would start by analyzing the existing system requirements and how the API will interact with the pay-on-foot machines. I will ensure that the integration is seamless and adheres to best practices for security and performance. I have a few questions for clarification: Q1 – What specific functionalities do you want the API to support (e.g., payment processing, user management)? Q2 – Are there any existing systems or databases that the API will need to integrate with? Q3 – What is the expected volume of transactions, and do you have scalability requirements in mind? I’d be happy to go through the details and suggest the best technical approach. Looking forward to hearing from you.

Hi there, I’ve read through your details and understand you need the Pay‑on‑Foot machine to talk to the Find My Car system and show location, images, and fees on the touchscreen before handing off to the existing payment flow. I’ve worked with Windows app dev, APIs, SQL, and hardware‑linked parking tools for years, so I’m comfortable working inside an existing setup. I’d keep it simple: • Add a module to send the API request and parse responses • Pull location, image, and fee from API/SQL • Update the touchscreen UI to show these clearly • Trigger your current payment process on the Pay button I can start right away and deliver within a few days once I have API docs and access. Can you confirm whether the Find My Car API returns both the vehicle image and stall coordinates in a single payload or separate calls? Greetings, Slavko
