Jackson Kasi, a developer from Peacock India, won the OpenFeature Aficionado prize in DevCycle's Feature Flag Challenge for his innovative Zero-Downtime PostgreSQL Migration project. Utilizing DevCycle feature flags, Jackson managed to migrate a high-transaction PostgreSQL database to a new environment without any downtime, ensuring data consistency by writing to both old and new databases simultaneously and gradually switching read operations. His project involved setting up feature flags to control database operations based on user contexts, automating data sync with PostgreSQL's Publish-Subscribe, and using DevCycle's Management API for dynamic control. Jackson's approach enabled real-world testing, validated the new database, and ensured seamless migration, inspired by a real client scenario of moving a database from a self-hosted server to the cloud. Known for his problem-solving skills, Jackson is also working on a Figma plugin to facilitate asset relations, aiming to benefit both developers and designers.
