Nita Neou (in der Community auch als Soph bekannt) arbeitet seit mehr als 15 Jahren in der Infrastruktur, die sich mit Netzwerken und Netzwerksicherheit befasst, in der Bank- und Öl- und Gasindustrie. Er mag Technik und Design, um zu verstehen, wie die Dinge funktionieren. Architekturdesign ist eine seiner Leidenschaften und er wird immer Zeichnungen haben, um seine Ideen und Gedanken darzustellen.

Bevor er zu Harmony kam, war er ein aktives Mitglied von P-OPS und half bei den wichtigsten Meilensteinen auf dem Weg zu Harmony: Staking, 8 to 2s Finality, EVM-Kompatibilität, Bridges, Testnets und mehr. Er liebt es, die Gemeinschaft und seine Mitarbeiter zu unterrichten, in der Hoffnung, dass alle gleich und in Harmonie sind.
