I turn good ideas into websites and digital experiences with a point of view. Thoughtful on the inside. Hard to scroll past.
A closer look at the products, people and ideas I’m bringing to the web.

A premium storefront, practical POS and automatic daily stock reports for a working neighbourhood shop in Kutus, Kenya.

Event discovery, ticketing and planning with your people. A product built around the feeling of going out.
A hands-on experiment in validation and clear feedback.
A focused partner for the design, development and refinement of your next project.
A clear story, considered design and a responsive experience that makes your next step obvious.
Turn a useful idea into an interface people can understand, explore and return to.
Thoughtful APIs, data flows and integrations to bring the moving parts of your business together.
Refine an existing experience: mobile layouts, accessibility, interactions and the paths that matter.
Good design is a series of small decisions. Try a direction, shape the corners, and watch the whole feeling change.
A bold idea deserves a little volume.

I’m Kencalvin, a developer in Nairobi with an eye for design and an interest in how things work.
I like the space where a useful idea becomes something you can actually use. That means thinking about the interface, the systems behind it, and how the whole experience feels on a phone.
CALDEV is where I bring that work together: websites, product interfaces, engineering experiments and notes from the process.
A shared direction, tangible progress and room to get the details right.
We talk about your audience, what the project needs to do and the constraints. Then agree on a focused scope.
Design and development turn that direction into something you can try. Feedback shapes the next iteration.
Check the experience across screen sizes, work through the details and prepare a clear handover.
A new website, a product idea, or something that needs to work better.
