Hi, I'm Berkay Çubuk. I build internal tools, dashboards and automations for small companies. You work directly with me from the first scoping call to handoff, and what I deliver keeps running without me.
AVAILABLE FOR NEW WORK — Q3 2026
Built to run without me.
Internal tools, dashboards and automations. Fixed price, delivered in two weeks, and yours to keep. No retainer, no lock-in.
WE SCOPE ON THE CALL · FIXED QUOTE WITHIN 24 HOURS
Internal tools, dashboards & automations for small companies.
Scoped in a free 20-minute call, quoted within 24 hours, delivered in two weeks. Projects typically start at $1,500 and the quote you get is the price you pay.
- 01
Internal tools
Admin panels, back-office apps and the small custom systems your spreadsheets are straining to become.
- 02
Dashboards & monitoring
Live views of your operations: sensors, machines and IoT fleets (MQTT a specialty), or plain business metrics.
- 03
Automations
The glue between systems you already use: syncs, reports, alerts and integrations that remove manual work.
- 01
A 20-minute call
You tell me what's slowing your team down. We define the scope together, on the call. Free, no obligation.
- 02
Fixed quote in 24 hours
One number, in writing. If the scope changes later, the new work gets its own quote. No surprise bills.
- 03
Built in two weeks
You see progress as it happens, and what lands is working software, not a deck or a prototype.

Handoff
Delivered documented and running. It keeps working without me, and you don't need a retainer to keep it alive.

You work directly with me.
I’m Berkay Çubuk, a software engineer. No handoffs, no juniors, no project managers: the person on the scoping call is the person who designs, builds, documents and delivers your software. I also run MQTT Studio, a live SaaS companies use to monitor their device fleets, so I operate production software every day instead of just building it.
- What does “fixed price” actually mean?
- The quote is the price. If you change the scope mid-project, the new work gets its own quote first, so you will never be surprise-billed.
- What fits in two weeks?
- A focused internal tool, a dashboard, or an automation with a clear job. Bigger systems are split into two-week deliveries, each with its own quote, so you see working software every two weeks instead of waiting until the end.
- What happens after delivery?
- The software is yours, documented, running and built to keep working without me. When you want more, the next round is scoped and quoted the same way.
- Can you work with what we already use?
- Yes. Most projects connect to the spreadsheets, databases and tools you already have rather than replacing them.
- How fast will you reply?
- Within one business day, usually much faster.
