This transition resulted in a 2x increase in queries per second (QPS) and a 50% reduction in fixed infrastructure costs. Awarded the "Instant Karma" recognition, with our team honored twice with the "Kool And The Gang" title for this achievement.2. Developed a Java Spring Boot-based backend for processing packing and invoicing orders in dark stores as part of the FK Minutes initiative.3. Designed the low-level architecture for FK Minutes order cancellation, tailored for dark store operations.4. Collaborated on product requirements and implemented service contracts for a new packing UI, contributing to the migration from a monolith to microservices-based architecture.

Resolved a critical bug that was delaying this transition.2. Successfully migrated the legacy WMS UI to Kubernetes in the staging environment. This task, originally planned for 2021 but delayed due to its complexity, was completed as part of the initiative.
