FAQ

What do you build with?

Mostly TypeScript on the edge (Hono, Elysia and Next.js on Cloudflare Workers and Vercel), Go and Rust for engines, Java with Spring where a team expects it, and Python where the models live. The backend page counts it.

Can I see the code?

Several are open source: Vectorless, BridgeHook, Selah, Mercala's backend and Polyglot bench. The rest are products; I can walk you through them.

How do you work?

Plan on a board first, state how the result will be checked, build on a branch, verify with the real build, review, merge. Every number on this site was counted from a repository or a live read.

Where are you?

Ibadan, Nigeria, on West Africa Time (UTC+1). I work remotely.
