- Cryptocurrencies and Blockchain
- Digital Media & Entertainment
- Digital Security
- Healthcare

In my last healthcare project, I had the privilege of being part of a core team responsible for refreshing a well-established healthcare application tailored specifically for dentists. The application had been operational for over two decades, and our mission was to modernize and enhance its functionality to meet the evolving needs of the dental industry. 
Collaborating with over 20 teams, we took on the challenge of developing the main components of the application. As part of the core team, I played a crucial role in designing and implementing the core functionalities.

For the backend of the application, we relied on Node.js in conjunction with the Nest.js framework, which enabled us to create a sturdy and scalable foundation for the app's functionalities. As for the frontend, we opted for the Electron application framework with Vue.js
In my next project, I want to focus on programming. I'm excited about tackling challenging coding tasks and improving my technical skills. I'm open to different industries, as long as I can be heavily involved in coding, troubleshooting, and optimizing software solutions.
