Senior Backend Engineer with 5+ years of experience, specializing in building distributed systems in Golang for video streaming platforms, e-commerce, and analytics platforms. Specialized in high-performance concurrent systems using goroutines, channels, and event-driven architectures. Proven track record of optimizing system performance and scaling production services.

Building scalable video streaming infrastructure:

• Designed and implemented a distributed video processing system in Go, reducing processing time by 83% (2h → 20m) through goroutine-based parallelization and worker pools.
• Built DRM-protected live streaming infrastructure handling 1000+ simultaneous encoding jobs with concurrent pipelines.
• Architected high-performance APIs serving 250K+ active clients with <50ms p95 latency.
• Developed event-driven microservices communicating via message streams with comprehensive testing (85%+ coverage).

Developed backend systems for mobile and web platforms:

• Built and maintained RESTful APIs for mobile, web, and admin platforms with focus on performance and reliability.
• Integrated payment gateways and third-party services with robust error handling and retry logic.
• Implemented CI/CD pipelines and managed production deployments with monitoring and observability.

Optimized e-commerce systems at scale:

• Reduced search latency from 21s to 350ms across 500K+ product catalog through query optimization and caching strategies.
• Increased large-scale web scraping throughput by 1200% via concurrency and pipeline optimizations.
• Developed and maintained Laravel-based e-commerce platforms including MounTruck and multi-vendor systems.
