about

An engineer who builds, understands and explores.

I am Adekunle S. Omorotimi, a full-stack and AI engineer based in Nigeria, working remotely with teams in the US and beyond. I have spent six years shipping production software across AI platforms, fintech, healthtech, e-commerce and Web3.

I started on the frontend and still go deep there, but the work has pulled me steadily down the stack: into APIs and data models, into deployment and security, and lately into agents and voice AI. Until November 2026 I led engineering across Sumeru Tech's products (the company was called Age of AI until recently), and I co-founded HODL, a fintech and blockchain product. At Sumeru Tech I set standards, mentored engineers, and wrote the code that has to work when a customer is on the phone.

What I enjoy most is the seam between a model and a product: how an answer becomes an interface, how a tool call becomes a business action, and how you prove the whole thing behaves. That is why this site has a lab: I keep testing, measuring and writing down what I find.

Three ways of working

  • The engineer

    Build

    Production software, end to end: React and Next.js frontends, Node and Python backends, Postgres, and the deploy pipeline underneath.

  • The AI systems builder

    Understand

    Agents, tool-calling, voice AI and evals, plus the architecture, security and reliability work that keeps them trustworthy.

  • The technical explorer

    Explore

    Experiments, benchmarks and write-ups. What worked, what broke, and what the numbers actually said.

How I approach problems

  1. 01

    Say what will happen before it happens.

    Snapshots before a cutover, validation before a reload, rollback on failure. I like systems that make their own failure modes boring.

  2. 02

    Put guardrails in code, not in prompts.

    A model can be wrong in new ways every day. The checks that matter run as ordinary code, and the model is measured against them.

  3. 03

    Measure the claim.

    Core Web Vitals, adversarial test sets, endpoint-by-role matrices. If a number is on this site, it has a source and a context.

  4. 04

    Teach what you learn.

    My degree is in science and technology education, and teaching has run alongside engineering the whole way.
