Experience building full-stack applications with modern frontend frameworks (React, Vue, Angular) and backend systems
Proficiency designing event-driven architectures using pub/sub messaging patterns and integrating distributed task queues (e.g., Celery) for asynchronous processing
Understanding of model serving patterns (REST, gRPC, async batching) and experience handling large-scale inference workflows in production
Knowledge of database systems (SQL/NoSQL) and integration with cloud data platforms (Snowflake, Databricks)
Experience with state management, session persistence, and efficient data flow patterns in distributed applications
