Sonu Yadav
Senior Backend Engineer · System design, data architecture & scale
I design and build backend systems that handle heavy data loads and complex business logic—with a strong focus on architecture, clear boundaries, and operational reliability.
Senior Backend Engineer with deep experience in system design and building scalable systems from the ground up. I own architecture decisions for data-intensive products: microservices, ETL pipelines, geospatial systems, and APIs that serve enterprise clients. I focus on clean boundaries, observable systems, and cost-efficient scale.
