As an independent Senior Backend Engineer, I architect and develop high-performance, secure, and scalable backend systems from the ground up using Clean Architecture principles. Key Achievements: • Architected and developed PingVertex, an enterprise-grade SaaS uptime monitoring platform with a custom Nano-USD Pay-As-You-Go billing engine and lease-based background schedulers. • Engineered a concurrency-safe E-Commerce Inventory API using advanced PostgreSQL row-level locking to guarantee zero race conditions during high traffic. • Built high-throughput real-time chat servers utilizing Tokio broadcast channels and WebSockets. • Developed complex Kanban project management APIs with strict Role-Based Access Control (RBAC) and native PostgreSQL full-text search. I specialize in Rust, Tokio, Axum, and advanced PostgreSQL, consistently delivering production-ready, heavily tested code for complex infrastructures.
