● Developed and maintained a production application serving 15,000+ users, ensuring high availability and low-latency response times during peak traffic conditions. ● Optimized backend throughput by 35% through async execution patterns, SQL query tuning, and strategic Redis caching, reducing database load during high-concurrency scenarios. ● Designed and implemented RESTful APIs for automated trading workflows, reducing manual operations by 50% through event-driven processing and queue-based task orchestration. ● Managed containerized infrastructure (Docker, Nginx, PM2) on Linux, implementing CI/CD pipelines and monitoring to improve deployment reliability and system observability.

● Engineered a high-performance system daemon in Rust using async runtime (Tokio), achieving a <50MB idle footprint through memory-efficient resource management. ● Architected a modular telemetry engine tracking 10+ metric categories with real-time data aggregation and accurate attribution across distributed endpoints. ● Implemented security-hardening features including global input monitoring and hardware-level access control, enforcing compliance across managed device fleets.
