Summary
🤩
RockstarMarcin Nowak-liebiediew is a pragmatic software engineer with nine years of experience building backends, data pipelines, tooling, and business-critical automation from Poland. He’s shipped production SDK tooling and CI/CD improvements at DFINITY, contributed AI-on-blockchain demos, and has a long freelance history delivering full-stack and data engineering solutions across cloud, Rust/WASM, and Python ecosystems. Comfortable from embedded IoT pipelines to React frontends and Postgres/GraphQL platforms, he favors practical, testable systems and has repeatedly reduced manual work equivalent to multiple FTEs through automation. Notably, his work spans both low-level performance concerns (Rust/WASM serialization) and higher-level platform ergonomics (configurable SDK extensions), reflecting a rare full-stack-to-toolchain perspective.
