PROFILE

Matej Hamas

Matej Hamas developed and delivered three features across apify/apify-cli and apify/apify-shared-js, focusing on API integration, CLI development, and frontend engineering using TypeScript and Node.js. In apify/apify-cli, he built the Actor Charge CLI, enabling pay-per-event billing with robust validation, idempotency, and event-count controls to ensure reliable charging workflows. For apify/apify-shared-js, Matej expanded the ACTOR_CATEGORIES constants by adding new categories for Agents and MCP servers, supporting better organization and discoverability of AI Agents and MCP-related actors. His work demonstrated depth in designing extensible categorization systems and implementing reliable, testable CLI features without introducing regressions or bugs.
