Senior AI Security & LLM EngineerFounder, SetherStreaming PII redaction for production LLM APIs
I help teams ship production LLMs and copilots without turning customer data into a compliance incident: boundary controls, evidence for auditors, and safer retrieval and agents.
- Production LLM & AI application security — PII redaction, logging, and controls aligned with what enterprise job specs now bundle as LLM security, AI governance, and GDPR / SOC 2 / HIPAA / EU AI Act expectations.
- Founder of Sether — open-source, streaming-native redaction for AI apps ( @raeven-co/sether on npm, MIT). Built so sensitive fields are tokenised before they cross your trust boundary to model providers.
- Senior Engineer, Must Company — high-traffic crypto / fintech product (70K+ DAU), NestJS, AWS, and production AI features for a Seoul-headquartered team.
- Secure RAG, agents & MCP — LangChain, LangGraph, and Model Context Protocol (MCP) for grounded retrieval and tool-using agents—the same ecosystem showing up across applied AI and platform job posts.
- Rust plus full-stack delivery — supply-chain and infra security tools on crates.io/npm, alongside TypeScript, Node.js, React, Next.js, and Flutter so I can own APIs, dashboards, and mobile surfaces—not only a notebook.
- Abuja, Nigeria · 7+ years in production · remote-first with a track record of async delivery for international companies.
