- 3. PHP DEVELOPER ADDICTED TO DEVOPS DMYTRO DANYLEVSKYI Back-End 80% DevOps 20%
- 4. LET’S DECOUPLE IT POTENTIAL MICRO-SERVICES FOR DRUPAL SITE ▸ Third party data synchronization tasks ▸ Data analysis and reports building ▸ Data scraping ▸ Heavy calculations performing ▸ Drush command
- 5. THAT PAIN… REMEMBER IT? ▸ Performing hook_updates (shared database) ▸ Mismatching of environment requirements ▸ Management of bloated composer.json file ▸ Your story?
