I developed an Android application, a RESTful web API service, and a web application for the VisitPro project.

This Android application runs on the VisitPro kiosk devices which work as self-service stations for factory visitors. The station collects the required information from the visitors, takes a photo of the visitor, plays a security information video, and applies a small test to visitors about the video content. Then if the visitor succeeds in the test, prints a passcard with the visitor's information, and photo on it and saves the visit data on a cloud database using the web API.

The Android application communicates with the web API service to store and synchronize the visitor's information and the visits.

There is also a web application that displays the visitors in the facility and provides the function to store the visitors' exit.

I developed three apps (Android, web, and web API) for the CRM requirements of a multinational company.

The Android application is used by sales representatives of the company. The app has a shared calendar on which a representative can create his/her sales activity plan and see the other representatives' activity plans. They can report their sales activities with the customer's information, create orders, and track their customers' orders status.

For this project, I developed Magento 2-based online stores and custom Magento 2 modules for product creation, pricing, and inventory synchronization for an online t-shirt retailer.

I built a special module that integrates the customer's product repository with online stores. The customer could easily select the product groups to publish on the store and upload hundreds of thousands of products to their stores. Also, I developed a module that synchronizes the inventory quantities of the products from the customer's inventory database. I deployed and optimized the stores on Nginx that runs on Ubuntu Servers.
