I build systems that work autonomously — trading bots, security tools, data pipelines, and AI-powered automation. Based in Indonesia 🇮🇩, available for remote contracts.

Telegram & Discord Bots — production-grade bots for trading, monitoring, community automation, and business workflows.

AI Agents & Automation — pipelines that monitor, analyze, and act without manual intervention. Integrations with Groq, OpenAI, and Claude.

Blockchain Tools — DeFi infrastructure, mempool monitoring, on-chain data analysis, smart contract security tooling.

Data Pipelines — scrapers, parsers, and scheduled delivery systems (web → email, API → Telegram, etc).
