Jack Byun

Traffic Management & Distributed Systems Engineering

• Architected high-performance automation frameworks in C++ and Go, reducing system latency by 30%+ and improving traffic handling efficiency by 40% across distributed AWS services

• Optimized Redis/Valkey caching strategies for high-traffic workloads, implementing intelligent traffic pattern analysis that prevented 40% of escalations

• Designed Kubernetes-based chaos engineering testbeds that uncovered 3 kernel-level bugs, ensuring resilience under extreme traffic conditions

• Resolved complex EC2 API Eventual Consistency issues through systematic TCP/IP and HTTP/HTTPS protocol analysis

Network Protocol & Performance Optimization

• Debugged and optimized TCP/SSL/HTTP protocol configurations across 13 AWS services (EC2, EBS, ElastiCache), handling 300+ critical networking cases with 100% SLA

• Implemented sophisticated load balancing and traffic routing solutions for production systems at AWS scale

• Analyzed traffic patterns and security threats using CloudTrail and network monitoring tools, proactively identifying bottlenecks

• Configured network protocols for distributed systems, improving throughput and reducing latency in production environments

Kubernetes & Container Orchestration

• Deployed scalable containerized applications on Kubernetes with full observability using Prometheus and Grafana

• Built resilient service mesh architectures for microservices, implementing circuit breakers and rate limiting

• Orchestrated container deployments with Helm charts, ensuring zero-downtime releases during traffic spikes

• Established observability practices with distributed tracing, providing real-time visibility into system health

Cross-functional Leadership & Innovation

• Led 2025 EMEA STEM initiative with 20 engineers, maintaining 95%+ milestone adherence while driving technical innovation

• Contributed automation frameworks adopted across multiple AWS teams, demonstrating open-source collaboration mindset

• Coordinated with SDE/TAM/SA teams to resolve critical issues including Bottlerocket CVE detection gaps

• Earned three prestigious awards (MVP, Rising Star, All-Rounder) for setting new performance benchmarks
