1. There was a lot of work, since the online store was created from scratch, it is rather big, and I wanted to make it as comfortable and convenient as possible. 
2. We have developed a Brandbook (in simplified form, this is a corporate identity). It included a design that would be interesting and understandable to the target audience. In this case, for children and teenagers who love "technical toys".
3. The "Personal Account", "Shopping Cart", and the "Favorites" section were developed. The check showed that they are easy and convenient for customers to use.
4. The filtration system turned out to be excellent. Now it's easy for consumers to find the product they need using 8 types of different search criteria. 
5. Special attention was paid to the product catalog. The whole range (and it's not small!) they were divided into groups and put with a detailed description and photo on the site. It took a long time, but everything was done without errors.
6. We have created an internal CRM system for processing applications received from customers. The staff of the online store also highly appreciated its simplicity and convenience.
7. Integrated payment was made for logistics. We have connected acquiring from Sberbank.
8. We carried out SEO optimization and made micro-markup. Now search engines recognize the content of the online store better, and it has become available to a larger number of users.
9. There was a lot of work on programming. Also, a modern and practical engine was installed here - MODX Revolution. Now everything is flying, without failures and delays.  
10. At the final testing, high indicators were obtained for the issuance of requests. The number of both visitors and buyers has become sufficient. The customer is completely satisfied! And we are happy about it!
