Two parallel products: Immo-GL (rental management, sole full-stack developer) and Immo-Solo (SCI accounting close, React frontend in a team). Billing engine redesign, Symfony 7 LTS migration, performance audit.

Key achievements

  • Billing engine redesign (Strategy pattern, prioritized calculators)
  • PHP 8.4 and Symfony 7.4 LTS migration, gradual and safe plan
  • Performance audit: N+1, missing indexes, React optimizations (memo, lazy, code splitting)
  • SCI accounting close screens (AGM minutes, reports, tax bundle)
