Laszlo Kiss

Freelance full-stack developer and UX designer. I turn ideas into working products in days, not months.

I have built daily games played by 600,000 people a month, a crowdsourced fuel finder made in a single day during a national shortage, and software for a startup and an investment bank.

  • Petrol station finder

    Retired

    Built in one day during the 2022 fuel shortage in Hungary, this crowdsourced fuel station locator helped over 150,000 visitors in a single day and was featured on major Hungarian news outlets. After the crisis it became a fuel price finder, and it was retired once commercial services caught up.

    Built with React, Next.js, Leaflet, Tailwind CSS, PostgreSQL, TypeScript
