What I'm looking for

I seek senior backend/ML/systems roles where I can build high-performance, cost-efficient distributed systems, lead teams, and drive measurable impact in collaborative, growth-focused environments.

I am a senior software engineer focused on backend, systems, and machine learning, building high-performance distributed systems using Rust, Python, and cloud-native technologies.

I've led engineering teams to Series-A, developed LLM inference engine components with SIMD and CUDA optimizations, and built a distributed SQL database implementing Raft, MVCC, and pluggable storage engines.

I deliver measurable impact — reducing processing times by 40%, cutting AWS costs by 20%, and migrating services to serverless for scale and cost efficiency — while contributing to open-source tooling and improving developer experience.
