Selected Work & Infrastructure

A deterministic systems engine written in Rust that ingests live telemetry from Bitcoin Core and LND, builds an in-memory graph, evaluates typed detectors, generates prioritized operational recommendations, and executes deterministic what-if simulations.

• ›Deterministic detectors with stable SHA-256 identities and zero replay duplication
• ›Pure what-if simulation engine projecting liquidity redistribution without mutating node state
• ›LLM explanations are strictly decoupled and never part of the core detection loop

A multi-tenant operational platform engineered to digitize municipal sanitation and environmental management from Makina Ward to Kibra Subcounty and Nairobi City County. Features QR attendance, leave approval workflows, field work evidence, and immutable reporting.

• ›Transitioned municipal workflows from unverified paper rosters to cryptographic QR check-ins
• ›Default-deny tenant isolation enforced server-side across staff, attendance, logs, and reports
• ›Private S3 object storage with scoped access control for sensitive field and medical evidence

An educational and experimental protocol workbench that constructs, executes, attacks, and verifies Bitcoin transactions against a live local Bitcoin Core node on regtest, producing deterministic cryptographic evidence bundles.

• ›Zero reliance on third-party block explorers; all state is verified against a live local Bitcoin Core node
• ›Hands-on experiments for RBF fee bumping, CPFP child spends, PSBT multisig signing, and Taproot scripts
• ›Deterministic proof bundle exports containing raw JSON-RPC queries, block receipts, and mempool proofs
