Programming on C

I am looking for a versatile developer for a permanent part-time collaboration on a DIY electronics project. We are building a line of kits that allow a person with no experience to assemble a finished device in an evening (smartwatch with an LED matrix, lamp with addressable lighting, weather station, plant sensor, etc.).What needs to be done: Evaluate device ideas: list of components, estimated cost, assembly complexity, feasibility. Assemble working prototypes (hardware + firmware) Test how feasible it is to provide the device to a novice: where they might struggle, what can be simplified, whether soldering can be avoided.Who I am looking for: Practical experience with ESP32 / Arduino: firmware, connecting peripherals (addressable LEDs, I2C sensors, displays). Ability to solder and work hands-on with hardware. Familiarity with existing firmware (WLED, AWTRIX, ESPHome, etc.) and sourcing components in Ukraine. Plus: 3D printing / modeling enclosures, experience documenting the assembly process.

What needs to be done: develop an EXE application in C++; create a modern graphical interface according to my design; implement the program logic; ensure stable operation on Windows 10 and Windows 11; provide the source code in Visual Studio (.sln, .vcxproj). I already have: interface design (screenshots attached); program operation concept; list of features to discuss with the performer. Requirements for the performer: confident knowledge of C++; experience with Microsoft Visual Studio; experience in developing Windows Desktop applications; neat and readable code; willingness to maintain communication during development. Please, in your response send: examples of your EXE programs; experience with C++; estimated completion time; cost of work.

Good day It is necessary to create a module that will work with the Firebird database in C++ for selling products. There are examples of ready-made solutions and a description of the module's functionality. Main functions: authorization, selection of products on the screen from groups/subgroups, transition to the cart, payment by card, and printing the receipt. The program must work on Windows 10 and above, using the existing database.

A patch is required for the graphics card driver that expands the capabilities of managing the graphics adapter by adding additional user settings. The patch must integrate into the existing driver architecture without disrupting its core functionality and ensure compatibility with supported versions of the operating system. The main goal is to provide more flexible access to parameters that are not available in the standard driver control panel, with the ability to modify them through a user interface or software API. The patch should provide a modular structure that allows for the addition of new parameters in the future without significant code redesign. It is necessary to ensure proper error handling, change logging, the ability to revert settings to default values, as well as maintain compatibility with future driver updates as much as possible. The solution should be accompanied by technical documentation describing the architecture, implemented capabilities, limitations, and testing recommendations.

We are a large logistics company with our own exports. We have a large fleet of vehicles and we constantly send our own vehicles for export to European countries.Description Website: https://echerha.gov.ua/ On this website, we place our vehicles in an electronic queue for crossing the state border. During registration, the following data must be entered: driver's first and last name; foreign passport number; email address; logistics phone number for notifications; type of vehicle (cargo); manufacturer's name of the vehicle; state registration number of the tractor; state registration number of the trailer; customs declaration number. A specific day and time for crossing the border is predetermined for each vehicle. For example, the vehicle must pass through the "Rava-Ruska" checkpoint on Monday at 10:00.Our Problem - The queue on the website https://echerha.gov.ua/ moves unpredictably. - For example, today is Friday, and the vehicle must cross the border on Monday at 10:00. - We do not know exactly when the queue will start moving. This can happen on Friday evening, at any time on Saturday or Sunday, early in the morning, during the day, or late at night. - When the queue starts moving, it is immediately visible on the website. Sometimes, within just a few minutes, it can move from Friday to Monday or even to Tuesday. - Because of this, logistics personnel are forced to constantly monitor the mobile application or website to not miss the moment when the queue reaches the required date and time. If this moment is missed, we physically cannot place the vehicle in the queue for the needed time slot.Task - After entering the vehicle data (for example, into a table or another interface, depending on the programmer's implementation), the system should automatically track the movement of the queue. - When the queue reaches the predetermined date and time, the system should automatically fill in the necessary data and place the vehicle in the queue without the involvement of the logistics personnel.
