I am an engineer who moved into product ownership, and I still write the spikes myself. I write the brief and the data model, choose the architecture and document why, ship it, then own the surface that sells it: the demo, the pricing, the waitlist, the docs.

Product Owner, MPC blockchain product line — a self-custody Web3 wallet and on-chain rewards at a fintech serving 90,000+ daily active users; shipped to BNB Smart Chain mainnet in August 2026 after multi-round smart-contract security review. Roadmap, OKRs, release decisions and settlement operations are mine.
Founder of Sether — open-source, streaming-native redaction for AI apps (@raeven-co/sether on npm, MIT). Sensitive fields are tokenised before they cross your trust boundary to model providers.
Six products shipped 0→1 — Fameely (family digital-safety platform, live), StreetAI (community-safety intelligence), MyLekki (client delivery), Sether, Raeven Reader and Raeven Marketplace. Concept notes, data models, pricing and launch surfaces included, not just the code.
Rust plus full-stack delivery — supply-chain and infra security tools on crates.io and npm, alongside TypeScript, Node.js, React, Next.js, and Flutter, so I can own APIs, dashboards, and mobile surfaces end to end.

Fameely
Family digital-safety and device-governance platform, founded and shipped from concept note to live product.
