Technologies: Flutter, Firebase, Visual Studio Code (VS Code)


2016 - 2017
Budapest University of Technology and Economics
  • Taught an advanced IMSc course on programming basics (C++) to electrical engineers at the Department of Automation and Applied Informatics (BME-AUT).
  • Created weekly assignments for the students and gave them grades after checking their results.
  • Made a set of interactive tutorials about C++ for each topic (about 500 pages long).
  • Motivated the students to pass the exams with good grades.
  • Assisted the students in my free time to help them understand the material more easily.

2013 - 2014
Freelance Developer
  • Provided a hosting server service for clients from all over the world, including game servers (Call of Duty 2, Call of Duty 4, and Minecraft), FTP service, and web hosting. I freelanced on this project, as I was still in high school at the time.
  • Implemented the front end and the back end by leveraging PHP and native JavaScript for dynamic user interactions.
  • Used Redmine to track user tickets and created Gantt charts to track the project status and resources.
  • Implemented an autonomous payment system by using premium-rate text messages (SMS). When the payment occurred, the user immediately received the credentials for his service in a user-friendly way.
  • Handled frequent distributed denial-of-service (DDoS) attacks.
Technologies: PHP, JavaScript, Linux, Java

iTransmit is a community-powered virus outbreak area identifier that enables users to:
• Check in if they are feeling sick.
• Check the map for infectious areas.
• Get notified when they meet an infected person.

I developed this application for a 24-hour hackathon and later extended it to be a part of my portfolio. As it turned out, unfortunately, I cannot publish it in Google Play Store or Apple AppStore as I'd need special approval from the national government of the country in question. If you are interested, I'm happy to share a demo.


PiggyBanx is the combination of gamification, social network, education, and the financial market! It changes the way of thinking. The youngsters can create various piggy banks with goals and amounts. The parents can control the youngster's activity and give them tasks. Piggy gives a friendly interaction when the user slides a coin into the piggy bank, and they can share their activity on their timeline.

PiggyBanx is a simple solution in the parent's hands to educate their children for financial awareness. It creates an interaction between the child and the parent because the parent can give daily tasks to the child, and in return, they earn extra piggy coins to their piggy banks.

We give the banks a great solution to be able to reach youngsters. We believe in a financially more educated future. Our goal is to provide a great tool that youngsters can enjoy. We also created Piggy as the chatbot with AI. Piggy can help the banks to keep in contact with the parents.

Front-end Development for Schönherz Zoltan Youth Hostel

I volunteered to develop a web front end for the hostel's Dynamic Domain Name System (DDNS) service. Many students in the hostel were future computer science engineers, and many of them had servers to experiment with. With our service, they were able to set an alias for the IP addresses of their servers.
