Hi, I'm Berkay Çubuk. I build software that shows companies what their machines are doing when nobody's standing next to them. I work alone, so you deal with me from the first call to the handover, and what I build keeps running without me.

BERKAY ÇUBUK

I'M TAKING ON NEW WORK · Q3 2026

I build software that shows you what your machines are doing.

Factory floor, job site, someone else's yard. If your equipment is somewhere you aren't, you usually find out about problems too late. I fix that. Fixed price, two weeks, and then it's yours. No retainer, nothing tying you to me.

I'LL SEND YOU A FIXED QUOTE WITHIN 24 HOURS

WHAT I BUILD FIXED PRICE · TWO WEEKS

You shouldn’t have to drive out there to find out if it’s running.

When your machines are somewhere you aren’t, you hear about problems late, and usually from the customer. I build the thing that tells you first. We work out what you need on a free 20-minute call, I send you one number within a day, and you have it two weeks later. That number is what you pay.

  1. 01

    Monitoring and alerts

    A live view of your machines, sensors or vehicles, wherever they happen to be. Set a limit and you hear about it before your customer does. I’ve been doing MQTT and IoT work for years.

  2. 02

    Internal tools

    Job tracking, maintenance logs, service scheduling. Usually the things your spreadsheet stopped coping with a while ago.

  3. 03

    Automations

    Connecting up the systems you already have, so nobody on your team is retyping the same numbers into two of them.

HOW IT WORKS WE TALK → I QUOTE → I BUILD → YOU KEEP IT
  1. 01

    We talk for 20 minutes

    You tell me what’s slowing you down. We work out what to build right there on the call. Free, and I won’t chase you afterwards.

  2. 02

    I send you one number

    In writing, within a day. If you want something different later, I’ll price that separately. You won’t get a surprise bill from me.

  3. 03

    I build it in two weeks

    You see it coming together as I go. What you get at the end is software that runs, not a demo or a slide deck.

  4. 04

    You keep it

    Documented and running. It works without me, and you don’t have to pay me every month to keep it alive.

WHO YOU’RE HIRING JUST ME

It’s just me.

I’m Berkay, a software engineer, and I work on my own. So the person you talk to on the call is the person who designs it, writes it, and answers the email when something breaks two months later. I also run MQTT Studio, which companies use to watch their own device fleets. That means I’m running monitoring software in production every day, not just building it for other people.

GET IN TOUCH I HAVE ROOM THIS QUARTER

Tell me what’s going wrong.

Twenty minutes on a call, one number within a day, working software two weeks later.

I WON’T PITCH YOU · I REPLY WITHIN A DAY
