I’m a designer who keeps finding new ways to make things.

My name is Toniloba Jolayemi, though most people call me Tonnie. I’m a product designer drawn to thoughtful digital products, complex systems, interaction, and the increasingly blurry line between designing and building.

I’ve led and owned design across multiple products and platforms, from AI-powered experiences and admin tools to websites, mobile apps, internal systems, and broader product creative direction.

Much of that work has meant operating as the sole designer10 projects, solo, moving between product thinking, research, UX, visual direction, and development collaboration to take ideas from early exploration to what eventually ships.

I’ve always believed there’s very little you can’t learn when you care enough to keep trying.

When something genuinely interests me, I find it hard to leave alone. I research it, test it, fail at it, try again, and keep going until I can do something meaningful with it. I often research things far beyond what the task requires too, I studied History & International Studies, so it’s a hard habit to break.

That’s how I learned to bake, how I explored dance and illustration, how I started designing, and how I now build products with AI.

Ideas I turned into working products.

These started as ideas I wanted to use myself. I built them with the help of AI, and kept improving them until they became real products I could share.

Before I built products myself, I learned how to take them all the way.

Birthyay started as a competition idea that I kept building on, shaping the product, designing the experience, and working closely with a developer until we launched on the App Store and Google Play.

That collaboration later led to Lenaz, an educational platform where I designed the student, tutor, and web experiences and helped take the product through to launch.

Both projects shaped how I work today: staying close to the product through development, solving what comes up along the way, and seeing an idea become something real.

The things that shaped how I make.

Everything above explains how I work. Everything below explains what shaped me into the kind of designer and builder I am today.

Interested in working together?

I’m always interested in thoughtful products, and work that gives me something new to learn.
