Data Engineer | I build AI systems that solve real business problems.

West New York, New Jersey, United States

About

I studied chemical engineering. I now build AI systems that solve real problems. I built a forecasting tool for a cafe chain after a barista told me they kept running out of bacon. I built a RAG system that reduced document lookup time by 80%. I built an observability framework that helps companies trust their AI agents. I do not just build tools. I solve problems. Open to roles in data engineering, AI engineering, or backend engineering. If you are building something that matters, let us talk. email [email protected] number 9084565420
