I build the whole system.

I'm Halis, an electronics engineer who also writes the software, runs the cloud, and ships the product. This page starts inside a copper wire. Scroll to zoom out.

Your cursor is a charge. Move it.

My first language wasn't code. It was electricity.

Electronics engineering was my first way of understanding the world. Transistors, embedded systems, FPGAs, robotics: things where a bad assumption can make smoke.

Software came later. I never saw it as a separate profession, just another material for making an idea real.

The ideas were never the weak part.

A smart-home system that reached TÜBİTAK-approved investment. An EEG-controlled wheelchair. Pressure-sensitive fabric for finding hardness in breast tissue. Visible-light communication for factory machines.

They did not die because the ideas were bad. They died because the inventor had no capital, no distribution, and no operator beside him.

Four builds from the bench

Then I built for the web, at scale.

I helped build Leesman into a serious global platform, back when writing the software was still the hard part. It taught me how systems behave under real users and real consequences.

Today I build web products, native mobile apps in Kotlin and Swift, and the AWS infrastructure behind them. Interface, API, data, deployment, and running cost belong in the same engineering conversation.

What is running now.

Products I designed, built, and operate today.

Mostly, I build because I like building. What feels hard to others is the fun part.

Still inventing. Now operating.

I run my products from saasappstudio and take on selected builds across web, cloud, and hardware. If you need a whole system built, from the circuit to the checkout, say hello.
