About
With 15+ years in software engineering and hands-on Rust experience since 2024, I specialize in building high-performance backend systems. From blazing-fast APIs to production-grade services, I leverage Rust's memory safety and zero-cost abstractions to deliver reliable, efficient solutions.
My recent work includes optimizing a cryptocurrency portfolio management API, achieving 30% faster response times and 10% lower memory usagethrough strategic connection pool optimization, structured logging, and multi-error validation.
Whether you need a new Rust backend built from scratch, performance optimization for existing systems, or migration from other languages to Rust, I bring deep expertise in the ecosystem including Axum, SQLx, tokio, and Tower.
Expertise
High-Performance APIs
Building blazing-fast REST and GraphQL APIs with Axum, Tower middleware, and async Rust. Optimized for production workloads with connection pooling and structured logging.
Database Optimization
Expert in PostgreSQL with SQLx for type-safe queries, connection pool tuning, and performance optimization. Achieved 30% faster response times through strategic pooling.
Systems Programming
Leveraging Rust's memory safety and zero-cost abstractions for reliable, high-performance systems. Building backend services that run efficiently with minimal resource usage.
Production Observability
Implementing structured JSON logging, distributed tracing, and metrics for production visibility. Making systems debuggable and maintainable at scale.
