USEFUL PRODUCTS, CAREFULLY BUILT

Full-stack, AI & Blockchain Dev.

I’m Omotosho David Ayomide, a full-stack, AI, and Web3 engineer based in Lagos. I build production-ready products across the entire stack—from interfaces and infrastructure to AI agents and smart contracts. I care about how they feel to use, how their parts fit together, and what happens when things go wrong.

What I build

I build marketplaces, dashboards, blockchain infrastructures, AI-powered applications, and developer tools. I built Beacon, a local-first tool that turns Git commits into reviewable social drafts; I also built RentLuxy end to end across its admin dashboards, backend, web app, and LLM integration. It’s a peer-to-peer home and car rental platform. I’m exploring natural-language wallet interactions with Ledgr on Sepolia, and I maintain streamkit, a vendor-agnostic library for streaming AI interfaces.

My work spans React and Next.js, backend systems in Node.js and Go, PostgreSQL, Solidity, and modern AI infrastructure.

How I work

I start by understanding the problem, then choose the simplest architecture that can support it well. I value readable code, clear boundaries, thoughtful testing, and interfaces that feel considered. Security and reliability shape those decisions from the beginning.

AI interests me because it brings new possibilities and new engineering questions around permissions, validation, memory, and human control. Blockchain raises its own questions about ownership and value. I enjoy working through those details and making the results useful and understandable.

When I’m not tinkering with blockchain or AI systems, you’ll find me listening to music or playing/watching football.

Here’s what I’ve been listening to lately.

TOOLS I REACH FOR

  • JavaScript
  • TypeScript
  • Golang
  • Solidity
  • Python
  • React
  • Next.js
  • TailwindCSS
