High-performance systems engineering in Rust.
Makers of UltraFastFileSearch — wire-speed NTFS file search.
Open source core. Commercial GUI/TUI in development.

A Rust-native file search engine that parses the NTFS Master File Table directly and answers queries in the single-digit millisecond range, even against tens of millions of records.

Numbers (v0.5.66, measured, 7 NTFS drives, ~26 M records):

• 26 M records → CSV in 13.6 s (1.72 M records/sec sustained)
• Hot daemon query p50: sub-millisecond on common patterns
• ~16× faster than the equivalent C++ reference on hot queries
• Linear memory: ~181 MB per million records

Open source under MPL-2.0. One engine, one daemon, one CLI, one TUI, one Python/Polars facade — all sharing the same MFT core.

A polished GUI and monetized TUI built on top of the open-source UFFS engine. Target users: developers, sysadmins, and incident responders who search millions of files daily and need something elegant and stupid-fast.

This organization is the public engineering portfolio of Robert Nio. The code under skyllc-ai/* is the work sample.

• Rust (2024 edition, async Tokio, unsafe where it earns the perf)
• NTFS MFT direct parsing, zero-copy record reads
• SIMD trigram indexing for substring search over tens of millions of records
• Multi-drive parallelism via a daemon + thin-client split
• Cross-platform: Windows (primary target), macOS (dev/offline analysis), Linux (daemon)

• Branch-protected main, PR-based workflow, signed commits (GPG, GitHub-verified)
• Nextest CI, REUSE/SPDX-compliant licensing, deny-unwrap workspace lints
• Reproducible benchmarks with published methodology and raw capture logs
• Architecture docs + user manual shipped with the code
• Conventional commits, semantic versioning

• Engineering roles / technical collaboration: uffs@nios.net
• PGP signing key: E406D32B4736D09F (ed25519, published on the GitHub profile)

Formal sponsor channels (GitHub Sponsors, Ko-fi) are in application/setup. Until those go live, the most useful things you can do:

• Star the UFFS repo
• Open an issue or file a PR — real-world use cases shape the roadmap
• Share the repo with someone who cares about fast tools
