About

6 years in Web3 — started in 2020, never left. My background is aviation (A&P certified, SMK 29 Jakarta), but I found my lane in blockchain infrastructure and community.

I run validators and nodes across multiple chains, manage cloud infra for blockchain projects, build communities from the ground up, and ship working prototypes. I'm the guy who understands both the tech and the people — bridging developers, communities, and protocols.

Currently exploring DeFi, on-chain security, and where DevRel meets growth.

What I Do

  • 🤝 Community & DevRel — CM at TradingLeagues, ZKsync, LayerZero, Sei Labs | Mod at Arbitrum & ZKsync | Building and growing Web3 communities
  • ⚙️ Node Operations — Running validators across Starknet, Sui, Q Blockchain, and more
  • ☁️ Infrastructure — Cloud infra for blockchain nodes at scale (AWS, Oracle Cloud, DigitalOcean)
  • 🔗 Building — Smart contracts, dApps, DeFi tools — shipping prototypes and getting things live

Tools I Work With

Solidity · Azure · JavaScript/TypeScript · Python · Go · React · Next.js · Tailwind · Docker · Linux · Nginx · AWS · Oracle Cloud · Alibaba Cloud
