• Optimize database migration processes, particularly for MySQL, ensuring data integrity and minimal downtime.
• Ensure smooth integration of subscription services and payment processes, with a focus on Stripe and Stripe subscriptions.
• Perform backend development tasks, including custom module development and third-party system integrations.
• Support and maintain the legacy Drupal 7 application while the migration is underway, ensuring stability, security, and performance.
• Handle critical bugs, system issues, and troubleshooting for the existing Drupal 7 site.
• Work closely with customer support and product teams to address issues, improve user experience, and ensure smooth operations.
• Write technical documentation, including migration plans, architecture decisions, API documentation, and workflows.
• Work with project managers to develop accurate project timelines and ensure smooth execution.
• Promote development best practices, including code reviews, CI/CD pipelines, and coding standards.
• Troubleshoot and solve complex backend challenges, ensuring a seamless migration experience for end users.

Qualifications

• 5+ years of experience as a backend or full-stack developer.
• 3+ years of hands-on experience in Drupal application development, with at least one major Drupal 7 migration project completed.
• Expert-level MySQL knowledge, including advanced database optimization, migration, and management.
• Strong PHP expertise, including custom Drupal module development.
• Proven ability to architect and execute complex migration projects, including creating estimates, schedules, and detailed Jira tickets.
• Experience supporting and maintaining legacy applications, including handling critical bugs and performance optimizations.
• Experience with payment processes and subscription services, particularly Stripe and Stripe subscriptions.
• Track record of writing clean, maintainable, and scalable code.
• Excellent technical documentation skills, with experience writing migration plans, API documentation, and architectural blueprints.
