• 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.

• Promote development best practices, including code reviews, CI/CD pipelines, and coding standards.

   

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.
• Strong background in API integrations and microservices architecture.
• Ability to balance migration work with ongoing support in a fast-paced environment.
• Obsessed with maintaining a clean, efficient codebase and enforcing best practices across the team.

• Fluency in English, both written and verbal.

   

Application Requirements:
