Eighteen years across distributed systems, cloud-native platforms, and security — from high-scale backends to blockchain custody and decentralized-network research. The tools that endured are gathered under TrustSentinel.
A drift from high-load systems toward security and decentralized-network research — described by the technology and skills, and where the projects were born.
Distributed, fault-tolerant server platforms at scale. JVM performance tuning, heap analysis, and cross-platform systems architecture.
Distributed systems for 10K+ concurrent users. Early Docker, Redis sharding, Kubernetes, CI/CD and event-driven pipelines, Linux OS tuning, IaC — and security hardening entering the practice.
Security engineering for high-traffic infrastructure: a DIY private cloud, Kubernetes-bound clusters, IaC, and OS-level hardening to sub-10ms P99 latency.
Secure custody for Bitcoin and multi-coin: Lightning Network Layer-2, hardware key custody (FIPS 140-2 L4 HSM), IAM, secrets management, STRIDE threat modelling, audit-grade event sourcing.
Doctoral research into the attack surface of blockchain P2P networks, decentralized identity (DID/SSI), self-custody and Layer-2 — alongside zero-trust architecture, service-mesh microsegmentation, and AI/LLM security governance.
