Frontend Engineer at Octopus Systems, building security dashboards and AI features for real-time operations monitoring.

Message

At Octopus Systems, I designed and developed dashboards and AI features for Command & Control platforms used in real-time security and operations monitoring. I built responsive interfaces with React, TypeScript, and Tailwind CSS, and integrated data from multiple systems.

At Dcentralab, I developed platform features from specification through testing and deployment. I used Web3.js to connect the frontend to blockchain networks and worked with backend and smart contract developers on contract logic and secure transactions.

As a freelancer, I designed and built a responsive jewelry e-commerce website with React and Node.js, including PayPal payments. I'm now building Tales of Budapest, a mobile audio-tour app with maps, on-demand historical narration, and walking tours.
