• Backend Development: Work with PHP (:5.6) in conjunction with Symfony (3.4) and zendframework/zend-db (2.8) to support and enhance backend operations.
• Cross-Functional Collaboration: Collaborate with UX designers, product managers, and backend engineers to align enhancements with overall product strategy.
• Transition Strategy: Contribute to the roadmap and execution of a technology transition over the coming years to a modern tech stack, which will include React for front-end development; Kafka, Go, and Rust for backend services; and advanced data storage solutions such as Parquet, Iceberg, Postgres, and other NoSQL data stores.
• Best Practices & Mentorship: Implement coding standards and best practices while mentoring junior developers on maintaining legacy systems and integrating new technologies.
