Cryptography Engineer & Blockchain Security Specialist with over 6 years of experience. Currently focused on QuickNode's Web3 Core infrastructure, leading the deployment, tuning, and maintenance of RPC nodes and validators across multiple blockchain protocols.

• Core Focus: Network lifecycle management (hard forks, state pruning), Kubernetes (K8s) architecture for volatile Web3 traffic, and infrastructure automation.
• Impact: Proven track record of securing $50M+ in digital assets and implementing high-standard cryptographic systems and HIPAA-compliant environments.

• $50M+ Secured: Institutional assets protected via AWS KMS, Gnosis Safe, and hardened custody protocols.
• 60% Optimization: Accelerated CI/CD pipelines for high-traffic Web3 gaming platforms.
• Zero Breaches: Flawless record in key-signing ceremonies and critical security operations.
• Global Scale: Infrastructure solutions adopted by over 1,000 Google Cloud enterprise customers.

• Infrastructure: Private Key Management, HSM Integration (Thales, IBM), JSON-RPC Protocols, and Validator/RPC Node Tuning.
• Advanced: Zero-Knowledge Proofs (ZKPs), Quantum-resistant cryptographic research, and Decentralized Identity.

• Orchestration: Kubernetes (K8s), Terraform, Helm, and Ansible.
• Automation: Developing internal tooling using Go, Python, and Bash/Shell.
• Observability: Managing SLOs, Error Budgets, and High-Severity incident response via Prometheus & Grafana.

Architected a cutting-edge solution utilizing Quantum Superposition and Zero-Knowledge Proofs (ZKPs) for verifiable on-chain randomness.

Designed a decentralized Hardware Security Module framework using Soulbound Tokens (SBTs) for enterprise compliance and identity management.

Developed automated toolsets for complex tasks such as real-time state-sync validation and rapid node recovery across EVM and non-EVM chains.
