BASE44 EXPERT | BASE44 APP DEBUGGING | BASE44 INTEGRATIES | BASE44 MIGRATIE | BASE44 STRIPE INTEGRATIE | REPLIT AI |


Je Base44 app moet functioneren als een premium bedrijfsasset als een MVP, SAAS of zelfs MMP.


Ik help oprichters, startups en bedrijven bij het bouwen, oplossen en opschalen van hoogwaardige Base44 apps die stabiel, professioneel en klaar voor groei zijn.


De meeste klanten komen bij mij nadat snelle oplossingen niet meer werken. Ik help bij het stabiliseren van Base44 apps die te maken hebben met gebroken workflows, inconsistente AI-gedragingen, gefaalde integraties, ontbrekende environment variables en nog veel meer (In feite op zoek naar de "volwassene in de kamer" om te helpen).


Ik richt me op het oplossen van de onderliggende problemen, niet alleen het patchen van symptomen. Dat betekent schonere logica, voorspelbare AI-antwoorden en apps die elke keer hetzelfde gedrag vertonen.


Wat ik help met:

  • Bugfixes en logica-aanpassingen voor Base44 apps.
  • Ontwikkeling van Base44 MVP apps.
  • Base44 integraties (API's, Stripe integratie, enz.)
  • Base44 app migratie naar Lovable/Wordpress.
  • Uitrol van Base44 apps naar App Store (IOS) en Playstore.
  • Oplossen van domeinproblemen (DNS).
  • Audit en verbeteringsreview van Base44 apps.
