FRACTIONAL SYSTEMS ARCHITECTURE / EST. IRELAND
Fractional Rust architecture for teams building embedded systems, critical infrastructure, and high-performance cloud services. From STM32 to distributed systems.
STM32, Nordic, TrustZone — from bare-metal to RTOS. Real-time systems with cryptographic attestation, designed for certification and decades-long service life.
Microservices, async runtimes (Tokio), WebAssembly, high-throughput systems. Zero-cost abstractions at scale — predictable latency without garbage collection.
Legacy C/C++ to Rust migration with a formal verification roadmap. Memory safety without performance loss — module by module, with measurable risk reduction.
No runtime garbage collector, no use-after-free, no buffer overflows. Roughly 70% of severe CVEs in C/C++ codebases are memory-safety defects — Rust eliminates the class at compile time.
Zero-cost abstractions: iterators, generics, and async compile to the same machine code you'd write by hand. C-level throughput with high-level ergonomics — on an MCU or a fleet.
The ownership model prevents data races at compile time. Fearless concurrency isn't a slogan — shared-state bugs simply fail to build, before they ever reach production.
/// Attest an enclave measurement against a hardware-rooted key. fn attest_enclave( measurement: &[u8; 48], nonce: [u8; 32], ) -> Result<Quote, AttestationError> { let report = tee::report(nonce)?; // signed by HW root key let quote = tee::quote(&report, measurement)?; quote.verify(trusted_roots::PSA)?; // constant-time verify Ok(quote) // no unsafe. no null. no data races. }
A 30-minute async brief on your system constraints — hardware targets, latency budgets, regulatory scope, team shape.
System diagram, crate structure, and full dependency audit — documented to a standard your board and auditors can read.
Sprint plan, risk matrix, and a team onboarding guide — sequenced so the riskiest components are de-risked first.
Monthly architecture review and code review. Decisions recorded, drift corrected, standards held as the system grows.
A five-day deep-dive into one system. You get the truth about your architecture, in writing.
A senior Rust architect embedded in your team, 12 hours per week, without the full-time hire.
Full-time embedded engagement for multi-system architecture programmes.
Led by F.A. Martin — Security Architect. 15+ years where failure is not an option.
Security Architect with 15+ years in industrial telemetry, telecom infrastructure, and IoT deployments across Europe. Systems designed here run in substations, factories, and carrier networks — environments where memory bugs are safety incidents.
Patent holder in hardware-rooted cryptographic attestation. Member of the Crypto Valley Association. Every engagement is led personally — never delegated to juniors.
No calls required. Async discovery. Board-ready architecture in 5 business days.
