Profile

Senior Software Engineer with 9+ years of experience building data-intensive platforms in the bioinformatics domain. I specialize in scalable data architectures and developer tooling, with strong ownership of production systems — including authoring the majority of a complex scientific platform. I bridge research and engineering by turning complex data workflows into reliable, maintainable systems.
