About Me

Backend and systems engineer focused on building reliable, fault-tolerant infrastructure where correctness and consistency are first-class concerns. Work centers on low-level systems close to the operating system, network, and storage layers, with particular attention to behavior under concurrency, crashes, and partial failure.

Experience spans systems programming and backend development, with a strong emphasis on understanding systems from first principles. Hands-on work includes building concurrent servers, Redis-like and Raft-based key-value stores, and write-optimized storage engines to explore real-world trade-offs in durability, consistency, and performance rather than relying on opaque abstractions.

Primary areas of depth include POSIX systems programming, write-ahead logging, LSM-tree storage engines, and distributed consensus protocols such as Raft. Actively seeking backend, platform, or infrastructure roles where reliability, recovery, and failure-aware design are core requirements.
