Having backups is not enough. The only real guarantee is having already restored them at least once.

02 — APPROACH
The database, the heart of the application
A slow page very often comes from a badly written query or a missing index. I design clear schemas and optimize queries so your site stays fast as your data grows.
I work with MySQL and MariaDB, in plain SQL or through the Eloquent (Laravel) and Doctrine (Symfony) ORMs, as well as on WordPress and PrestaShop databases.
DESIGN
Well-thought-out tables, relations and constraints.
PERFORMANCE
Indexes, EXPLAIN analysis, rewritten queries.
RELIABILITY
Backups, tested migrations, consistent data.

05 — FAQ
SQL: your questions
My site is slow: is it the database?
It is often one of the causes. I analyze the slowest queries, add missing indexes and rewrite costly queries, then measure the gain.
Can you migrate data from one platform to another?
Yes: export, cleanup, transformation and import, with data checks before going live.
Do you set up backups?
Yes, regular backups that I check can actually be restored: a backup that has never been tested is not a real backup.
