Bitcoin & Open-Source Developer building operational systems, protocol tools and accessible Bitcoin infrastructure.
Specialized in deterministic Bitcoin/Lightning operational intelligence, reproducible protocol laboratories, production open-source collaboration in BTCPay Server, and technical Swahili Bitcoin education.
Flagship Systems & Laboratories
Rieko
Operational intelligence engine for Bitcoin and Lightning 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
MazingiraOps
Multi-ward environment operations platform
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
BitScope
Reproducible Bitcoin protocol laboratory backed by a real Bitcoin Core node
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
BTCPay Server & Ecosystem
Fix 22 dead sidebar entries in Integrations and Plugins sections
Audited the documentation sidebar configuration and restored 22 missing or broken links across the Integrations and Plugins directories, ensuring docs build cleanly.
Sidebar config references pages that don't exist, breaking the build
Surfaced and documented non-existent file references causing build breakages in the static documentation generator.
Complete Swahili translations across all merchant and pos flows
Finished missing and inconsistent Swahili translations for Point-of-Sale, invoice checkout, and store management views.
feat(translations): add Swahili (sw) language pack
Created initial Swahili language pack, establishing standardized translations for Bitcoin, Lightning, and payment gateway terminology.
Making Bitcoin Knowledge Accessible in Kiswahili
East Africa is home to over 200 million Swahili speakers and vibrant grassroots adoption. Technical Bitcoin documentation, however, has remained almost entirely in English. I lead community initiatives to translate definitive protocol literature and merchant interfaces into Kiswahili.
Mastering Bitcoin
Swahili translation coordination for the 3rd edition.
BTCPay Server
Complete Swahili POS and checkout language pack.
Grassroots Cohorts
Hands-on node & wallet workshops in Kibra, Nairobi.
