I secure Bitcoin infrastructure through applied cryptography and systems engineering.
My background in Site Reliability Engineering gives me a foundation for understanding production systems at scale. Now I specialize in the security layer: analyzing and hardening cryptographic protocols, auditing confidential computing implementations, and building secure infrastructure for Bitcoin applications.
- 🔐 Core Focus: Bitcoin protocol security, threshold cryptography (FROST, MuSig2), confidential computing (TEEs)
- 🧰 Current Role: Senior SRE at Bitnob — Building Bitcoin & Lightning infrastructure for Africa
- 🔬 Research Interests: Threshold signature security models, side-channel resistance, key management protocols
- 🌍 Location: Lagos, Nigeria → Relocating to Estonia/Europe (2026)
- 🎯 2026 Goal: Transition into Bitcoin infrastructure security engineering with focus on cryptographic protocol implementation and security auditing
I work at the intersection of cryptography, security engineering, and Bitcoin infrastructure.
Security Engineering:
- 🔍 Security analysis of threshold signature schemes (FROST, MuSig2)
- 🛡️ Hardening cryptographic implementations (constant-time operations, nonce security)
- 🔐 Auditing confidential computing deployments (TEEs, attestation, side-channels)
- 🧩 Threat modeling for Bitcoin infrastructure (attack surface analysis, mitigation strategies)
Applied Cryptography:
- 🔑 Threshold signatures (FROST, MuSig2, ROAST)
- 🧮 Key management protocols (DKG, key ceremonies, backup/recovery)
- 🔒 Confidential computing (AWS Nitro Enclaves, remote attestation)
- 📊 Security auditing (protocol analysis, implementation review)
Infrastructure:
- 🏗️ Production systems (Kubernetes, Terraform, high-availability architecture)
- 📈 Security observability (monitoring, anomaly detection, incident response)
- 🔧 Supply chain security (reproducible builds, dependency verification)
Tech Stack:
- Languages: Rust, Go, Python, Bash
- Bitcoin: Bitcoin Core, rust-bitcoin, Bitcoin Dev Kit (BDK)
- Cryptography: secp256k1, FROST, Schnorr signatures, PSBTs
- TEEs: AWS Nitro Enclaves, attestation protocols
- Infrastructure: Kubernetes, Terraform, Helm, AWS
- 🔐 Building Bitcoin + Lightning infrastructure at scale serving 100k+ users across Africa
- 🧹 Led migration of legacy systems to Kubernetes with zero downtime
- 🛡️ Implemented infrastructure security automation and compliance frameworks (PCI-DSS, SOC2)
- 🔭 Built observability pipelines for real-time Bitcoin transaction monitoring
- 🧠 Currently building production Bitcoin custody systems with TEE backing
