Senior Frontend Engineer · Frontend Architecture · TDD
Senior Frontend Engineer with 6+ years of experience building scalable ecosystems, Microfrontends, and high-traffic platforms (14M+ monthly visits). I care about engineering discipline — 100% TDD, Extreme Programming, and Domain-Driven Design — and about the architecture decisions that let a product move fast without breaking.
