Hi, I’m Yanelys — a full-stack software engineer building scalable backend systems and the product experiences that sit on top of them.Contact me
ABOUT ME
I’m a full-stack software engineer focused on building and scaling distributed systems and data-intensive platforms. At IRU, I work on a large-scale vulnerability detection platform powered by Kafka and PostgreSQL. My work spans backend systems, data pipelines, and performance optimization across services handling high-volume data. I focus on building systems that are reliable, scalable, and designed for real production constraints. On the backend, I work with distributed pipelines, Kafka consumers, and aggregation systems that power large datasets and improve data processing performance. On the frontend, I build React dashboards that turn complex backend data into usable, high-performance interfaces. Previously at Markforged, I worked as a full-stack engineer leading a migration to React and TypeScript, while building dashboards, UX tools, APIs, and backend integrations. I enjoy working across the stack, especially where backend systems, data infrastructure, and product experience intersect. I’m particularly interested in scalable systems and high-ownership engineering environments.
