Summary
👤
Senior🎓
Top SchoolBartosz Mikulski is a Principal AI and Big Data consultant with 15+ years of experience turning broken AI/ML proofs-of-concept into reliable production systems, routinely diagnosing root causes in hours or days rather than quarters. He’s engineered MLOps platforms and high-throughput pipelines for startups and large-scale services—co-creating Qwak’s core platform, supporting systems that handle billions of events and tens of billions of monthly requests, and stabilizing data infrastructures at Fandom. His strengths lie in production rescue: RAG and hallucination control, robust schema-enforced inference layers, agent orchestration, and deployment strategies (shadow, canary, zero-downtime) that minimize business risk. A prolific educator and author, he’s trained 1,000+ engineers, contributed to O’Reilly, and speaks at major industry events, which reflects his blend of hands-on debugging skill and scalable architecture thinking. An unconventional detail: he often finds the single failing format or parsing assumption that cascades through microservices and fixes it in a day, turning chaotic prototypes into 95%+ accurate, production-grade systems.
