I build Agentic AI tools that deliver transformative results

Martin Melišek

This is my personal portfolio: what I've made, what I've learned, and what I'm working on now. It's also a space to share those learnings.

    Agent Tokenwatch

    Local, metadata-only token and cost telemetry for Claude Code, Codex CLI, and GitHub Copilot CLI.

    A dependency-free Node.js CLI that captures local, metadata-only token and cost telemetry for Claude Code, Codex CLI, and GitHub Copilot CLI. Installs lifecycle hooks where available, feeds supported status lines, and ships a set of tw-* skills.

    Atlas Data Fabric

    Enterprise data migrations die in spreadsheets. Atlas makes the mapping governed, queryable and agent-ready.

    The governed workspace for core-system data migrations. Agents and humans share the same features but not the same authority: agents propose, people approve, and every decision is audited. Approved mappings become the specs ETL is built from. Proprietary, available through Itera.

    A free, vendor-neutral course on how coding-agent harnesses work and how to build on them safely.
