How a top works, and how we do

Balance

Simple where it can be

Architecture sized to the problem: no platform for a script, no script for a platform.

Momentum

Small steps, every week

Working software early and often. You always know where the project stands.

A fine point

One problem at a time

A top spins on a single point. We focus the same way, and measure before we optimise.

Built and run by us

We run our own products in production. It keeps our advice honest.

What clients say

“I have had the pleasure of working with Diyaz nearly a year now on our consumer software product. He is an exceptionally talented and experienced software developer and architect. We are a small company and resources are tight. Diyaz has been boundlessly creative in finding the best ways to improve our product and solve issues. He understands that compromises must be made and his recommendations are always well thought out and achievable. Above all he is a great person and will be the first I contact for future needs.”

Russell Wilson
Director, Innovation & Emerging Technology-Director, Akj Enterprises LLC United States

“Diyaz has a rare ability to make complex technical ideas sound simple without losing depth. Having worked with him as a software architect and later taking his communication course, I learned that his clarity isn’t just natural talent—it’s built on practical, learnable techniques. The course immediately improved how I structure my thoughts, persuade others, and spot communication gaps in real-time. I highly recommend it to any tech or business professional looking to elevate their impact.”

How it works

About

Hi, I'm Diyaz.

I've spent 15 years building software. Today I build AI systems as a Toptal AI Engineer, research Kubernetes at the edge at Tampere University, and run TopTop from Finland.

I like problems that need both a working system and a clear explanation of why it works.

Tell us what you're building.

A 30-minute call, no slides. You'll leave with a next step either way.
