Experience
Banner Management System
A banner management system for a large-scale gambling company includes all possible advertising types such as static banners, pre-roll video ads, real-time updated banners, marketing emails, marketing SMS, and Facebook ads. This is a platform where customers can create a new banner of any type and send it to website owners to place it on their pages.
Analytics
Placing Google Analytics code on a website will increase page size and badly affect its performance. To maximize page loading speed, I developed a Google Analytics alternative package written in Laravel that can be used for any website.
After installing the package via Composer, the user gets access to the personal analytics dashboard, which has a set of all possible data filters. Since the package is working in the background, it runs as a queued job and doesn't affect performance. It tracks route visits itself, and there's no need for additional JavaScript files in a website source code.

Social Platform
I created a back-end functionality for a social website that was a combination of Facebook, Kickstarter, and blockchain.
It was a social platform where users could communicate via messenger, share statuses, photos, videos, and startups and their progress, create detailed projects, ask for funding in cryptocurrency, post job openings, and hire people.

Laravel Admin Panel
An admin panel package for Laravel for creating a dashboard and the whole website.
The user sets up the configuration in the package, including modules and fields each module should have. After running the script, the package generates the whole website structure, such as databases, modules, relationships, resources, controllers, and routing, with its fully functional admin panel.
