Freelance software developer building at the intersection of AI, crypto, and the open web. One-person studio, ambitious ideas.
ernawatidjuansjah.devI'm a freelance software developer with a genuine passion for AI. I build smart, practical tools that help individuals and small businesses get more done — powerful technology shouldn't only belong to companies with big budgets.
My work spans AI agents, non-custodial crypto systems, and open protocols. This site is intentionally simple: black, white, and to the point.
A non-custodial crypto trading platform with an AI agent, CIPHER-1, that prepares trades and assesses risk — but never moves funds without your wallet signature. Built on Base with USDC settlement and x402 agent-to-agent payments.
