AI engineer, 2+ years of LLM systems in production. Agent systems in production on Mastra, retrieval up to full GraphRAG for pharma compliance documentation, 85% of queries resolved without escalation. Recent open source work merged into mastra-ai/mastra. I treat evals as release gates, an agent feature without one is a demo. Flexible hours: full EU overlap, US hours work too. No visa sponsorship needed, B2B contractor or via EOR.
