About
I’m Steven Johnson, a senior systems engineer, systems architect, and technical lead with 15+ years of experience designing and building complex production systems across distributed infrastructure, backend platforms, embedded environments, and high-availability operations.
I have a strong hands-on background in Rust, Go, Python, and C/C++, spanning protocol design, backend services, networking, automation, and performance-sensitive systems. I combine deep engineering capability with architectural judgment and technical leadership, including shaping designs, guiding implementation, mentoring engineers, and driving difficult work through to production. I’m actively developing DNTLS, a decentralized naming and trust layer for autonomous agents and AI systems, and I bring a track record of patented software and systems innovation to every project.

Founded Sakura Industries LLC to commercialize patented technologies and provide contract engineering, systems architecture, and advisory services. Led the design of DNTLS as a hybrid on-chain/off-chain system, defined protocol, trust, and identity models; architected cryptographic and resolver foundations; implemented reproducible build/delivery pipelines; and guided architectural decision-making across protocol, infrastructure, and integration layers. Wrote production-grade Go, Rust, and Python components and provided technical leadership across distributed systems and production engineering.
Technical architecture lead for Cardano’s decentralized treasury and innovation fund platform (Project Catalyst), managing $150M+ in community funding. Led distributed systems architecture, protocol design, and engineering pipelines across governance, voting, treasury, and decentralized data systems. Implemented on-chain/off-chain RBAC for secure hybrid participation; stabilized Jörmungandr-based production voting; designed a decentralized proposal and voting database; engineered a high-performance chain indexing/traversal system using PostgreSQL and Scylla/Cassandra; co-developed Hermes, a decentralized application node; designed reproducible CI/CD pipelines around Dagger and GitHub Actions.
Senior engineer and technical lead for the Privacy Hero secure home router product. Built backend services in Go, Python, and Rust; maintained and extended a large production Go codebase for routing and firewall engines; designed REST and WebSocket APIs with OpenAPI/AsyncAPI; migrated workloads to GCP; developed embedded firmware components, low-level router software, and an unbrickable firmware loader; built an OpenWRT-based build system; led architecture across backend, firmware, and infrastructure.
