Rust systems
Backend and systems-level Rust: correctness, performance, soundness.
JOSE ROBLES · FRACTIONAL HEAD OF ENGINEERING · RUST / BITCOIN / AI
Technical due diligence for software, AI and Bitcoin systems.
I help founders, investors and technical leaders detect software risk fast — architecture, dependencies, maintainability, security signals, AI governance and delivery risk.
FLAGSHIP OFFER

- Dependency, supply-chain and delivery risk
- Security signals and red flags
- Prioritised risk register with severity and effort
PROOF, NOT CLAIMS
Evidence packs
Public, reproducible sample packs generated by my Rust due-diligence toolkit on real open-source projects. They show the exact workflow and artifacts a real engagement produces — executive report, scorecard, evidence, risk register, review questions and methodology. (These are method demos, not endorsements or final verdicts on the projects shown.)
