Background About me

I design and ship systems that transform complex financial data into approachable, actionable insights. Over the past two decades, I've led engineering teams across global investment banks, building platforms that power trading desks and quantitative strategies. My work spans the entire stackβ€”from real-time data pipelines and cloud infrastructure to elegant user interfaces.

Passionate about the intersection of finance and technology, I specialize in fixed income analytics, equity derivatives, and cryptocurrency markets. Recently, I've been exploring how streaming architectures and modern web technologies can deliver real-time market insights with exceptional user experiences.
