AI and cloud platform engineer building agentic developer tools, repository automation systems, local-first AI operators, retrieval platforms, and full-stack AI applications.
- Agentic software-engineering systems: review agents, repo automation, reusable agent skills, subagents, and governed PR workflows.
- Full-stack AI products: Next.js, React, TypeScript, Bun, Vercel AI SDK, AI Gateway, Supabase, Neon, Upstash, Convex, and modern app-router architecture.
- Cloud and platform engineering: AWS, Vercel, Cloudflare, Docker, GitHub Actions, CDK/IaC, OpenAPI, observability, and release automation.
- Local-first operator tools: Rust CLIs/TUIs, SQLite, safe automation loops, review-first workflows, and deterministic audit trails.
- Retrieval and document intelligence: RAG, hybrid dense/sparse search, GraphRAG, MCP, Qdrant, pgvector, LlamaIndex, LangGraph, and privacy-preserving LLM workflows.
- Mobile and cross-platform surfaces: Expo, React Native patterns, web/native product flows, and app deployment workflows.
