Projects

Jun 2019 — present

Homelab

I have completely redesigned our home network from the ground-up. I installed CAT5e cables to every room and created a centralised location for all of the rack-mounted networking equipment in the attic. I configured everything from the router, modem, set up VLANs, APs and created different SSIDs for IoT devices. I also added multiple servers for self-hosting services like Plex, Bitwarden, Blue Iris, Nextcloud and to backup our most important files to the cloud using Backblaze B2. Furthermore, I added a loads of IoT devices to the household to monitor and control many aspects of our home. During this project, I learned a wide variety of things from crimping CAT5e cables, through basic networking to complex firewall rules.

Oriental Soup House native iOS app

Associated with Best Oriental Soup Kft.

I created with a small team of 3 a complete application for the Oriental Soup House restaurant franchise application which served in production through AppStore.

Jun 2020 — Feb 2022

Crypto-mining

Associated with Princeton University

I am a cryptocurrency enthusiast, thus I started using the spare-time of my desktop to sell my hash power in exchange to bitcoin. I have been mining for a few years now and I have learnt so many things about blockchain technology, finance and investing. This led to my current setup, which is a 6 GPU mining RIG in our garage. I profoundly believe that cryptocurrencies are something we have to keep our eyes on.

Apr 2019 — Apr 2024

Converse Brand Ambassador

I am one of the many influencers who are part of the ConverseAllStar global community. I often work with others to create creative projects.
