Senior Data Engineer specializing in secure, observable data platforms and event-driven architectures.
What I'm looking for
I am a Senior Data Engineer with 5+ years building data platforms, observability infrastructure, and event-driven systems, with recent focus on regulated, high-security environments.
I design and implement streaming architectures (Apache Kafka), Azure analytics solutions, and deterministic testing frameworks to deliver auditable, production-grade data services.
I have driven measurable outcomes—reduced onboarding time, lowered cloud costs, improved latency and adoption metrics—while implementing IL4/IL5-compliant delivery in air-gapped contexts.
I prioritize reliability, observability, and secure design, and I integrate modern ML/LLM retrieval pipelines and automation to support self-service analytics and enterprise knowledge retrieval.
