Global Remote | US Timezone Aligned | B2B via OnTimeStack or EOR via Deel/Remote. I'm a Senior Software Engineer and technical leader with 15+ years of experience building software, data, analytics, and AI-enabled platforms for global teams. My strongest work sits at the intersection of: • AI Engineering: RAG systems, LLM-powered assistants, semantic retrieval, OpenAI, LlamaIndex, Vertex AI • Data Engineering: ETL/ELT pipelines, BigQuery, Redshift, SQL, analytics infrastructure, data quality • E-commerce Technology: event tracking, conversion analytics, recommendation systems, storefront integrations • Platform Engineering: backend systems, cloud architecture, observability, integrations, and scalable product delivery Most recently, I delivered a production-ready RAG-based Slack knowledge assistant for AlpineIQ in under one month, helping teams retrieve cited, confidence-scored answers from documentation, support content, internal knowledge, and source code. At Terpli, I helped build the technology foundation behind an AI-powered cannabis e-commerce assistant later acquired by AlpineIQ. I worked across frontend, analytics, tracking, experimentation, ETL, and technical leadership, including designing the analytics layer that became central to proving ROI for B2B clients. I'm especially interested in roles involving AI products, data platforms, enterprise AI, analytics engineering, e-commerce technology, and SAP BTP / SAP Business AI as part of my current enterprise platform expansion. I work best in environments that value ownership, technical depth, pragmatic architecture, measurable business impact, and high-quality execution.
