Open to remote, hybrid and freelance work

Hi, I’m Serine.I build web apps that are fast, typed, and kind to the people using them.

Five-plus years shipping production frontends for enterprise clients, government platforms and my own products. I care about architecture that stays simple as teams grow: generated API clients, reusable component systems, and measurable performance.

    What changed

    • Spec-driven API contracts enforced at the type level, cutting integration defects.
    • Reusable component library on Tailwind and Styled Components shared across features.

    What I solved
