CodeQuery Microservices Migration
Decoupled monolithic web application into service-oriented architecture with event-driven background queues.

Overview
Incremental migration of a core monolithic application toward a scalable, decoupled microservices architecture. What I built - Service boundary definition and API contract separation between core services - Event-driven task queue pipeline for asynchronous workloads - Database interaction optimization for heavy query paths - Release management and VPS deployment automation with zero-downtime strategies Engineering highlights - Transitioned blocking tasks to asynchronous Redis queue workers - Decreased API bottleneck latency by 45% on high-traffic endpoints - Standardized error handling and cross-service observability
