Hey, I'm Cay

I build digital products that scale

Full-stack and AI engineer shipping production software across geospatial intelligence, healthcare, fintech and public-service platforms. I work end to end, from architecture through Nuxt and Next frontends, NestJS and Nitro backends, LLM agents and retrieval layered on top of them, SQL, Docker and CI/CD. I care as much about the people using a system as the code behind it.

How I build

One product, three layers.

I work the whole stack rather than a slice of it. That means the screen someone touches, the services behind it, and the data underneath. Owning all three is what makes the trade-offs between them mine to solve.

  1. Interface

    The part people actually judge you on. It has to be accessible, fast, and built to survive a slow connection on a mid-range Android.

    • Nuxt
    • Next.js
    • Vue
    • Tailwind

  2. Services

    The API surface and the work behind it: auth, jobs, integrations, agent orchestration, and the boring reliability that keeps a product trusted.

    • Nitro
    • NestJS
    • Node.js
    • REST
    • LangGraph
    • vLLM

  3. Data

    Schemas designed before the first endpoint, migrations that are safe to run twice, and queries that stay fast as rows pile up, relational and vector alike.

    • Prisma
    • PostgreSQL
    • Docker
    • CI/CD
    • MySQL
    • Redis Vector Search

About

How I work

Four things show up in every project I take on, whether it is a satellite data platform for Mozambique or a booking system for a salon in Kumasi.

End-to-end delivery

From requirements and wireframes through to deployment and support. Nuxt, Next, NestJS, SQL, Docker and CI/CD, all handled by one engineer across the whole stack.

Premium UI/UX

Design-thinking led interfaces with real visual hierarchy, accessibility and responsiveness. Product feel is a requirement, not a polish pass.

Secure by default

Application hardening, access control and encryption strategies on platforms that handle whistleblowing reports and child-protection cases.

Impact first

e-Government, public health and education tooling aligned with Ghana's digital transformation agenda and the UN Sustainable Development Goals.

Experience

Where I have shipped

Client platforms, a company of my own, and volunteer work that put engineering behind child protection.
