Professional Trajectory

Professional Trajectory

Nine years of frontend engineering across e-commerce, B2B SaaS, and automotive cybersecurity, with three years of design practice before that, and independent client work since 2025. I have seen jQuery spaghetti become React ecosystems, and led teams through the migration.
