I developed the entire application stack for the hosting management system, including the front and the back end. The back end, called Devil2, is the core that manages all services offered by the company. I developed it in Python (Django framework), and it uses a variety of solutions, including message queues; multithreaded and multiprocessing programming; and various libraries, including PostgreSQL and MongoDB.

I created the front end, called DevilWeb2, using Django and jQuery. The whole suite allows any customer of MyDevil.net to easily manage their hosting account, including websites and DNS zones, mail accounts, databases, and FTP accounts. MyDevil.net still uses DevilWeb2, which is fast and secure and has been acknowledged as the best, easiest-to-use web-based management system. Implementing this system and the CRM system (described below) made it possible for the company to increase its userbase by more than 300%.

The essential utility allows customers to order new services and pay for their current ones. It's the biggest system I created while working at MyDevil.net. I developed it using Python (Django framework) and integrations with many third-party services. The CRM system supports new and recurring payments, notifications, invoices, and automatic account management, such as creation and blocking. It also supports a variety of automatic online payment systems. This system and the account management system (described above) made it possible for the company to increase its userbase by more than 300%.

A data analytics app used to provide food-related regulatory compliance information to corporate clients. I led the development of the app as a fresh start project. It was created using Angular (two at the time, five when I left), Django, PostgreSQL, MongoDB, Oracle Database, and Redis. The app was a major step forward for the company, as it was a rewrite (plus new features) of a legacy app, using modern technologies and a much more pleasant design.

A Django, Vue, and AngularJS-based app for context-based ad intelligence. The app allows you to target your ads/collaborations better and collaborate with content creators that match your target audience. As a software developer, I contributed to the application in basically all areas: I worked on the back end (bugfixes, maintenance, new features, and improvements), front end (planning and coordinating AngularJS to Vue migration), and DevOps (managing deployments, Dockerizing the application, configuring the CI/CD pipeline).
