Project link: http://ziphol.ru/

Briefly about the project: Service center and at the same time a store of spare parts for household appliances. 21 years of successful work, in the presence of more than 5000 parts, spare parts, consumables and chemicals for household appliances.

What has already been done: The basic functionality of the online store has been developed. Technology Stack: Php8.0, Laravel, Mysql, Nuxt, Elasticsearch, Swagger, Gitlab CICD, Docker, PhpUnit

Now you need to perform the remaining tasks, because the main programmer was transferred to another project.

Task list:

1). Finalize the exchange of goods between 1C and the site. (The main integration has already been implemented)
Set up a scenario with the removal of product photos in 1C (now the photo is not deleted on the site)
When you change any information on a product, 1C immediately adds it to the exchange list as a change. And when exchanging, 1C sends not only the changed information, but all the information about the product. The same thing happens with pictures.

2). Configure the record of the parameters of the goods for delivery (weight, length, width, height). Parameters should be pulled up from 1C.

3). Set up order integration (two-way integration between 1C and the site)

4). Integration with transport companies such as BoxBerry DPD PEK Russian Post. Calculation of cost and delivery time.
