Marcela Řezková · AI Engineer · Product builder
I design products and build them with AI agents.
Knowledge-driven agent orchestration, full-stack and data engineering underneath, and a product mindset that starts from market data.
Czech Republic · open to AI & R&D teams in Europe
What I do
Agentic AI systems: multi-agent orchestration with clear roles (planner, implementer, reviewer), MCP integrations, and knowledge networks that give agents the context they need. Full-stack and data foundation: React/Next.js frontends, Python/FastAPI and Rust services, DuckDB/SQL analytics, ETL pipelines and CI automation. Product and delivery: from market data to a shipped product, with opportunity analysis, unit economics, specification, and delivery with measurable results.
How I work
Validate with data. Specify and plan. Build with agents, review with agents. Ship and measure. Creative when there is room to explore, decisive when I know what I am holding, and always anchored in data.
Selected work
Agentic market-opportunity platform: a local AI orchestrator in Rust that scores emerging opportunities and produces a daily brief. Automotive data platform with multi-agent development: five-layer ETL, deal-scoring engine and a React frontend. Analytics tool for regional government: an API-first FastAPI service detecting stale investment actions. Production web apps with bookings and payments. Labour-market and pricing analytics with DuckDB and interactive dashboards.
