• • High-Performance Caching: Developed Kache, an in-memory datastore in Go with sharded map architecture for concurrent, efficient key-value storage
• • Advanced Features: Implemented TTL with background janitor for automatic expiry and LRU eviction policy with configurable max size for optimal memory management
• • Robust Operations: Supported essential cache operations (Set, Get, Delete, Exists, Flush) with comprehensive test cases ensuring reliability and scalability

• • Built a scalable task management system using Kafka for distributed messaging and worker-based architecture to execute tasks asynchronously
• • Designed resilient task flow: API submits tasks → Kafka queues → Workers consume and process → MongoDB stores results
• • Implemented exponential backoff retries with a Dead Letter Queue (DLQ) for persistent task failures
• • Used Docker for containerizing services

• • Secure Code Execution: Isolated code execution using Docker with strict CPU, memory, and process limits for enhanced security
• • Concurrency Control: Implemented a custom semaphore to manage concurrent execution requests efficiently
• • Robust Error Handling: Developed secure shell command automation with detailed error logging and runtime exception handling
