How I work

Careful work on sites that can't go down

I'm Lotfi Otmanine, a senior WordPress developer with 7+ years of hands-on work. Through OLDEV I work with agencies, companies and founders, and every project follows the same four rules.

  1. Diagnose first

    I find the real cause before changing anything, then confirm the scope with you.

  2. Staging first

    Changes are built and tested on a copy of your site, not on the live one.

  3. Reversible changes

    Every step has a way back, so a problem never becomes an emergency.

  4. Written handover

    You get documentation and measured results, so your team stays in control.
