I build production-grade backend systems using Rust, Axum, Tokio, PostgreSQL, and Redis.
Currently working on enterprise Warehouse Management Systems (WMS) focused on:
- concurrency-safe inventory workflows
- multi-tenant backend architecture
- async queue processing
- transaction correctness
- operational reliability
I enjoy designing backend systems that remain predictable under load, fail safely, and stay maintainable over time.
