Rust-focused software engineer working on AI systems, runtime tooling, local-first infrastructure, Linux systems, and performance-minded backend engineering.
I build practical systems where backend engineering meets developer workflows: async Rust services, CLI tools, model tooling, integration tests, local-first developer infrastructure, and automation that makes complex systems easier to validate.
- AI systems: local model workflows, model tooling, runtime/debug utilities, and correctness-focused validation.
- Rust systems: async services, CLIs, MCP servers, WASM runtimes, and durable local tooling.
- Linux-first engineering: reproducible environments, build/debug workflows, shell/Rust utilities, and CI-minded checks.
- Open-source contribution style: small scoped changes, explicit validation, and reviewable technical scope.
| Project | What it is | Stack |

| VeroID | Identity/lab project with local agent state and iOS-side experiments. | Rust/project tooling, iOS, agent workflow |
| DeFiScan | Data collector around DeFi metadata, chain/platform sources, and external APIs. | Rust, Diesel, Postgres, reqwest, simd-json |
| rag-mcp-server | Minimal Rust MCP/RAG server prototype with a JSON search API. | Rust, Rocket, Tokio, serde |
| exe | Personal command runner for Linux setup, development tooling, and repeatable environment automation. | Rust, CLI, Linux, Git, Docker |
- I prefer small, explicit systems over opaque frameworks.
- I care about runtime behavior, local-first tools, clear source-of-truth boundaries, and reproducible workflows.
- I use Rust when reliability, performance, or long-lived tooling matters.
- I use Python when model tooling, data work, or fast iteration is the right tradeoff.
- I value narrow PRs, local reproduction, focused tests, and reviewable technical scope.
- I have older but still useful background in QA automation, Selenium/Playwright, API testing, and Linux administration.
