I build digital products that solve real problems.
I’m Marvel Adeniyi, a full-stack software developer. I design and build websites, web applications and the systems behind them — frontend, API and database.

Frontend, API and database
SettleNG runs on a PostgreSQL schema with authentication, statement import and reporting — not just a storefront.
See it →What I do
Frontend, backend and the database between them.
I work across the stack, so a screen, an endpoint and a table are designed together instead of handed between three people.
Frontend engineering
Interfaces in React and Next.js: component architecture, responsive layouts and the small details that make a product feel finished.

Node and NestJS services, REST endpoints, authentication and the business logic behind the screens.

Relational models in PostgreSQL with Prisma, migrations, and the queries that keep records correct as a product grows.

About
An engineer who ships, not a designer who stops at mockups.
I studied Computer Engineering at Ekiti State University and chose software engineering as my specialisation. Since then I’ve built for law publishing, retail, fitness, photography and small-business finance.
I care about the whole product: the problem, the person using it, the data behind it and whether it still works six months after launch.
How I work
Four steps, no surprises.
The whole process, start to launch — played out scene by scene.

Scene 1 of 4: Understand. What the product must do, who uses it and what is already there.
The reel
Six frames. Six live products.
