Description

I help teams build faster, safer, and more reliable data and backend systems with Rust and Python.

My work focuses on high-performance data pipelines, Python acceleration with Rust, Arrow-native processing, backend reliability, deterministic systems, and reproducible performance benchmarks.

I have published Rust crates and Python packages, including ProofFrame, an Arrow-native data validation engine, and Calybris Core, a deterministic decision kernel with replayable audit evidence.

I can help with:

• Rust backend development with Axum, Tokio, Tower, and tracing

• Python performance optimization using PyO3 and maturin

• PyArrow, Pandas, Polars, CSV, and Parquet data pipelines

• Data validation, dataset fingerprinting, and row-level evidence

• Rust code audits, benchmarking, concurrency testing, and CI

• API design, persistence, structured errors, and observability

I work remotely from Türkiye and can collaborate across CET and EMEA time zones. For each project, I provide clear scope, tested code, documentation, and measurable delivery results.

Independent / Open Source
Independent Rust & Python Engineer
May 2024 - Today (2 years and 3 months)
Bursa, Türkiye
I independently design, build, test, benchmark, document, and publish Rust and Python infrastructure for data-intensive and reliability-sensitive systems.

My work includes ProofFrame, an Arrow-native data quality engine published on PyPI and crates.io, and Calybris Core, a deterministic decision kernel with replayable audit evidence. I work across Apache Arrow, PyO3/maturin, Axum, Tokio, Polars, cryptographic proofs, tamper-evident logs, concurrency testing, CI, packaging, and reproducible performance benchmarks.

I am available for Python data-pipeline acceleration, Rust backend development, architecture reviews, reliability audits, data validation systems, and remote contract projects across CET/EMEA.
