    We are looking for a company / programmer who will be able to perform regular updates of our Windows (PC) application for us. Currently, we have completed cooperation with the developer of the application and have received the source code for this application. The application is written in Qt/C++ language. It is a music application with access to 2 music players, where some of our users log in. Logging in, reading playlists in the players is done via API - JSON from our main service. Currently, we need to implement a third player in it - offline. It is to be an exact copy of one of the already available players in this application (PLAYER 2), with the difference that a given playlist is to be downloaded immediately in its entirety and thanks to this playback is to take place already without the Internet, and not as in the current player 2, where the downloading takes place on a track-by-track basis. The budget for the implementation of this update is PLN 1000 gross, as this price is performed for us in the rest of the same applications but for other platforms. The application is available for download at the following link: In case of interest we will send access to a test account. In addition, information for the rate per hour of work is welcome, because as I mentioned at the beginning - we are primarily interested in permanent and long cooperation. The service is growing rapidly and 2-3 times a year we report more new improvements / modifications to be implemented. I am available for any questions. Tomasz Kowalczyk

    Turulo - Wordpress handyman 7 deals
    I will commission a real estate search engine table similar to the one in the attached link - I want to enter data for the table in the CMS Wordpress panel using CPT (Custom post types). The search engine must operate on the data entered into the fields created with the ACF (Advanced custom fields) plugin. The design should be made so that I can style it using CSS and prepared in such a way as to allow the creation of new columns with new search options. Simple instructions are welcome, I would like the whole module to be placed in a php file that I can freely call in different places on the page using the "get_template_part()" function. I would also like the results in the table when filtering, to load similarly to under the link, that is, without reloading the whole page. I think the best option would be to create such a table on a clean installation of Wordpress, along with the necessary plugins, on which the contractor could prepare according to the above-mentioned guidelines, the finished product. And the contractor could log into the panel to see how everything works from the inside. When the work is completed, it would be possible, with the help of a simple all in one wp migration plugin, to create a copy which the contractor would upload to his target site. Please feel free to make an offer, best regards ;)

    Hello, I would like to download data via APi from wholesaler - ultimately to wodpress/woocommerce store. I am looking for a person to create an integration : Api -> Microsoft Access - Downloading data from the above mentioned site as MS Access tables. I would use MS Access to classify products once to create queries. Of course, it does not have to be MS access. Api can be directly integrated with woocomerce or other intermediate software. The data must be retrieved periodically and in the store itself it must be possible to set a cron sentence to update prices and stocks. The macma wholesaler offers product labeling - I don't need variant labeling selection data and calculations. The data I need: - description - features (color, material, brand) - photos, - prices, - stocks - categories - subject categories (sets) In total, everything but the calculation and its application (calculate). Ideally, the link should be created on the basis of an already working solution.

Job description

We are looking for a company to design and implement an application aimed at 2 main functions:

- creating a Conceptual Design of a photovoltaic installation from scratch with the possibility of generating designs to pdf.

- creating a price offer by writing out a cost estimate for the client.

The system would be managed from the administration panel, where advisors will be able to manage their profiles.


Anyone with access to the panel will be able to:

• check previously created offers (only yours, and the site administrator all);

• create a new / edit an offer:

- based on the entered data, i.e.

• reporting the annual consumption from the previous billing period (kWh unit);

• selecting the type of photovoltaic panels (selection from the database);

• selecting the inverter (selection from the database);

• specifying the length of AC and DC cables;

• providing the number of roof slopes;

• selecting the type of structure (selection from the database);

- additional choices:

• whether there is to be a fire arrangement;

• additional ground works;

• additional options (please clarify whether the price for a service / product will depend on something, or will they be individual elements with a fixed price?); - the introduction of a margin;

• generate a PDF with an offer;

• generate PDF with the project

The system will stand alone:

• prompted:

- the appropriate number of panels;

- appropriate inverters (range 80-120% of panels power);

• calculated:

- the exact power of the installation;

- selection of AC and DC cables;

- maximum and minimum number of modules per chain; - energy yield

- ecological effect

- list of elements of the photovoltaic system

- the ability to add and delete photos

- possibility of an electronic signature at the customer's site

The result will be a PDF file.

The application should be operated on any device: phone, tablet, computer. Additionally, we would like to start selling the application through app stores, with the possibil
