How I work

  • From request to task

    I join client discussions with a teammate and turn requests into concrete technical tasks.

  • Finding bugs

    I read the server logs and trace the logic until I find where it breaks, then fix it.

  • Across the stack

    I work on frontend and backend, so a fix can go from the database to the screen in one change.
