Stefanos Anagnostou is a Senior Software Engineer based in Athens with nine years of experience building reliable web applications and UI components. Currently at Clerk, he focuses on front-end robustness—contributing tests and React fixes to the widely used clerk-js authentication library to improve component reliability. His background spans full‑stack development in multi-tenant architectures, database and query design (Oracle/PL-SQL), and maintaining legacy systems from roles at Covve and the Hellenic Army. Comfortable across React, PHP/Symfony, and API documentation, he blends hands-on engineering with strong system design and clear documentation practices. An early career detour as an editor-in-chief hints at strong communication and product-minded instincts beyond pure engineering.
